Defining creativity in the age of AI Display until July 1, 2025 Creativity MJ25-front_cover.indd 1 4/2/25 1:1 PM Sponsored Content The Agentic AI Advantage: Unlocking the next level of enterprise value I ntelligence versus agency. That’s the distinction between generative AI—which has already created tremendous disruption and opportunity across businesses— and agentic AI, its next evolution, says Swami Chandrasekaran, Global Head of AI and Data Labs at KPMG LLP. AI agents are powerful, controlled autonomous software entities that can fulfill goals by taking actions. They leverage the capabilities of large language models (LLMs) to reason, understand expressed goals (beyond simple promptresponse patterns), take actions using one or many tools, make decisions, dynamically adapt, learn from feedback, and interact with other agents to fulfill larger workflows. They are proactive and help achieve predefined goals while involving humans in and on the loop as necessary. How can AI agents unlock more value? AI agents can unlock greater enterprise value in at least three key ways. First, because agents are more powerful, independent, and not limited by working hours, they can automate more complex tasks and processes, expanding the number of hours per day that work gets done. Second, they require less effort to drive human adoption— a key barrier with GenAI— which allows organizations to scale more rapidly. Third, once several agents have been implemented within an enterprise, they can interact seamlessly while continuously learning from both human feedback and their own experiences. This enables them to not only improve existing processes but also 1 fundamentally transform how work gets accomplished through their collectively reinforced intelligence. By working seamlessly with human employees, the GenAI augmentation potential can be up to 4 percent to 18 percent of EBITDA, or 19 percent to 23 percent of salary cost annually, depending on the sector, according to KPMG research comprising analysis of 17 million companies and 3 billion data points.1 Agentic AI will unlock even greater enterprise value by automating complex tasks and embedding AI more easily into the workflow.” -Per Edin, AI Go-to-Market Leader – Global Advisory and US Tech, Media and Telecom Sector, KPMG LLP The KPMG TACO Framework™ To help organizations navigate the variety of agentic capabilities and match them to use cases, KPMG has developed the TACO framework, which classifies AI agents into four categories: Taskers, Automators, Collaborators, and Orchestrators. • Taskers execute well-defined, repetitive tasks with minimal complexity. The “human in the loop” supplies detailed instructions on what needs to be achieved, rather than how to achieve it. • Automators execute end-to-end processes, orchestrate related tasks, manage dependencies between tasks, and dynamically engage tools or APIs as needed. • Collaborators function as adaptive AI teammates, working interactively with humans to execute meaningful actions, while adapting dynamically to user feedback and changing contexts. • Orchestrators coordinate multiple agents and interdependent workflows, managing dynamic resource optimization and multi-agent choreography. Orchestrators are the most sophisticated form of AI agents. By intelligently coordinating complex agent ecosystems, they can unlock entirely new business models, dynamic pricing strategies, harness distributed knowledge networks, and enable resource optimization at unprecedented scale.” -Swami Chandrasekaran, Global Head of AI and Data Labs at KPMG LLP The art of moving quickly: Address challenges and concerns early To move at market speed in adopting agentic AI, organizations must address several challenges and concerns early: 1. Decide how to acquire agents Decide whether to build, buy, or partner to acquire AI agents, considering the needs, resources, and strategic goals of the organization. Building AI agents in-house allows for customization and control but requires deep expertise in AI, data science, and software Quantifying the GenAI opportunity, March 2025, KPMG U.S., https://kpmg.com/us/en/articles/2025/quantifying-the-genai-opportunity.html © 2025 KPMG LLP, a Delaware limited liability partnership and a member firm of the KPMG global organization of independent member firms affiliated with KPMG International Limited, a private English company limited by guarantee. USCS028154-1A Untitled-6 1 3/31/25 1 :11 M Sponsored Content development. Buying pre-built AI agents offers rapid execution and efficiency but may have limited customization options. Partnering with external vendors combines the benefits of both building and buying and allows for risk and cost sharing. 2. Elevate security, privacy, and ethics Develop robust security protocols to protect sensitive data and maintain the integrity of AI systems. Implement protocols for encryption, access controls, and continuous monitoring for potential threats. Conduct regular stress testing, bias detection, and fail-safe mechanisms to prevent errors and ensure the reliability of AI agents. Ensure transparency into how AI agents are built and monitored and that the data used to train AI agents is free of bias. 3. Consider the workforce impacts Build a skilled workforce capable of collaborating with AI agents by providing targeted training and upskilling programs on AI technologies, data science, and machine learning. Consider hiring new talent with expertise in AI to help design, implement, and manage AI agents effectively. Integrate AI agents into the organizational structure, defining their roles and responsibilities, and adapting performance and feedback processes. AI agents should be integrated into the team, with clear reporting lines and defined roles. How do we get started? An agentic-AI roadmap The integration of agentic AI into your organization can be transformative. To help you navigate this journey, we have outlined a series of first steps: 1. Articulate your vision Develop a comprehensive vision and strategy for AI integration that aligns with your organization's long-term goals. Identify areas where AI agents can address pain points and add the most value, such as routine tasks, complex workflows, or customer interactions. Extract tacit knowledge from domain experts to define agent goals, behaviors, and decision-making criteria. Use tools like the The KPMG TACO Framework™ to identify the types of AI agents that can best address your needs and determine which departments and processes are most appropriate for agentic-AI applications. 2. Progress from pilots to scaling Start with pilot projects to test the effectiveness of AI agents in specific areas of your business where they can have the most impact. Put metrics in place to evaluate the pilot outcomes, as well as mechanisms for gathering feedback and learnings. Once you complete several successful pilots, develop a plan to scale and operationalize AI agents across different departments and processes in your organization. 3. Develop an agentic-AI governance playbook Expand existing AI governance programs to account for the unique challenges and opportunities presented by agentic AI. Create a living catalog of AI agents to track their purposes, dependencies, and performance metrics for effective scaling and governance. Ensure compliance with legal and regulatory considerations by staying ahead of emerging regulations and industry standards. 4. Establish performance metrics Continuously measure and optimize agent performance to ensure the delivery of desired outcomes. Develop clear performance metrics to evaluate effectiveness, including error rates, processing times, and customer satisfaction. Continuously improve AI agent performance by refining algorithms, updating training data, and implementing new features. Balance tangible benefits, such as increased profitability and cost savings, with intangible benefits, such as improved employee experience and successful transition to new roles. Unlocking the full potential of agentic AI The transition to agentic AI represents a transformative leap forward for businesses. By embracing the proactive and dynamic capabilities of AI agents, organizations can drive significant new value in terms of increased revenue, productivity, and cost savings. By employing a structured agentic classification system, organizations will be well-equipped to align current agent types with appropriate use cases that drive short- and mid-term value. At the same time, organizations will be laying the groundwork to be well positioned for the transformative impact of more sophisticated AI agents that are on the horizon. These will create not only longerterm value in operations, but also entirely reinvented business models and industries. ********** Per Edin is the AI Go-To-Market Leader for KPMG Global Advisory and US Tech, Media and Telecom Sector, KPMG LLP.

Carrie Klein, Carly Kay, Matthew Ponsford, and Robin George Andrews. (If you’ve ever wanted to know how we might nuke an asteroid, this is the issue for you!) We’re also trying to get a little more creative ourselves. Over the next few issues, you’ll notice some changes coming to this magazine with the addition of some new regular items (see Caiwei Chen’s “3 Things” for one such example). Among those changes, we are planning to solicit and publish more regular reader feedback and answer questions you may have about technology. We invite you to get creative and email us: newsroom@ technologyreview.com. As always, thanks for reading. Mat Honan ROBYN KESSLER he reason you are reading this letter from me today is that I was bored 30 years ago. I was bored and curious about the world and so I wound up spending a lot of time in the university computer lab, screwing around on Usenet and the early World Wide Web, looking for interesting things to read. Soon enough I wasn’t content to just read stuff on the internet—I wanted to make it. So I learned HTML and made a basic web page, and then a better web page, and then a whole website full of web things. And then I just kept going from there. That amateurish collection of web pages led to a journalism internship with the online arm of a magazine that paid little attention to what we geeks were doing on the web. And that led to my first real journalism job, and then another, and, well, eventually this journalism job. But none of that would have been possible if I hadn’t been bored and curious. And more to the point: curious about tech. The university computer lab may seem at first like an unlikely center for creativity. We tend to think of creativity as happening more in the artist’s studio or writers’ workshop. But throughout history, very often our greatest creative leaps—and I would argue that the web and its descendants represent one such leap—have been due to advances in technology. There are the big easy examples, like photography or the printing press, but it’s also true of all sorts of creative inventions that we often take for granted. Oil paints. Theaters. Musical scores. Electric synthesizers! Almost anywhere you look in the arts, perhaps outside of pure vocalization, technology has played a role. But the key to artistic achievement has never been the technology itself. It has been the way artists have applied it to express our humanity. Think of the way we talk about the arts. We often compliment it with words that refer to our humanity, like soul, heart, and life; we often criticize it with descriptors such as sterile, clinical, or lifeless. (And sure, you can love a sterile piece of art, but typically that’s because the artist has leaned into sterility to make a point about humanity!) All of which is to say I think that AI can be, will be, and already is a tool for creative expression, but that true art will always be something steered by human creativity, not machines. I could be wrong. I hope not. This issue, which was entirely produced by human beings using computers, explores creativity and the tension between the artist and technology. You can see it on our cover illustrated by Tom Humberstone, and read about it in stories from James O’Donnell, Will Douglas Heaven, Rebecca Ackermann, Michelle Kim, Bryan Gardiner, and Allison Arieff. Yet of course, creativity is about more than just the arts. All of human advancement stems from creativity, because creativity is how we solve problems. So it was important to us to bring you accounts of that as well. You’ll find those in stories from 4/1/25 12:2 PM Services, solutions and platforms that use generative AI technologies.

MJ25-front_thedownload.indd 7 Over the winter, eggs suddenly became all but impossible to buy. As a bird flu outbreak rippled through dairy and poultry farms, grocery stores struggled to keep them on shelves. The shortages and record-high prices in February raised costs dramatically for restaurants and bakeries and led some shoppers to skip the breakfast staple entirely. But a team based at Washington University in St. Louis has developed a device that could help slow future outbreaks by detecting bird flu in air samples in just five minutes. Bird flu is an airborne virus that spreads between birds and other animals. Outbreaks on poultry and dairy farms are devastating; mass culling of exposed animals can be the only way to stem outbreaks. Some bird flu strains have also infected humans, though this is rare. As of early March, there had been 70 human cases and one confirmed death in the US, according to the Centers for Disease Control and Prevention. The most common way to detect bird flu involves swabbing potentially contaminated sites and sequencing the DNA that’s been collected, a process that can take up to 48 hours. 4/2/25 2:1 PM 08 The Download BY CARRIE KLEIN Data In mid-March, the US Centers for Disease Control and Prevention said there had been 70 confirmed human cases of avian influenza A(H5) in the US since April 2024, linking 26 to exposure to infected poultry. By that time, the US Department of Agriculture estimated, A(H5) had affected more than 90 million birds, from both commercial and backyard flocks. The CDC said the immediate risk to the general public from the virus was low. Carly Kay is a science writer based in Santa Cruz, California. MJ25-front_thedownload.indd 8 Coming to a spa near you: Heat by bitcoin Bitcoin enthusiasts are using a side effect of mining’s immense computational load to heat hot tubs, office buildings, and homes. At first glance, the Bathhouse spa in Brooklyn looks not so different from other highend spas. What sets it apart is out of sight: a closet full of cryptocurrency-mining computers that not only generate bitcoins but also heat the spa’s pools, marble hammams, and showers. When cofounder Jason Goodman opened Bathhouse’s first location in Williamsburg in 2019, he used conventional pool heaters. But after diving deep into the world of bitcoin, he realized he could fit cryptocurrency mining seamlessly into his business. That’s because the process, where special computers (called miners) make trillions of guesses per second to try to land on the string of numbers that will earn a bitcoin, consumes tremendous amounts of electricity—which in turn produces plenty of heat that usually goes to waste. “I thought, ‘That’s interesting—we need heat,’” Goodman says of Bathhouse. Mining facilities typically use fans or water to cool their computers. And pools of water, of course, are a prominent feature of the spa. It takes six miners, each roughly the size of an Xbox One console, to maintain a hot tub at 104 °F. At Bathhouse’s Williamsburg location, miners hum away quietly inside two large tanks, tucked in a storage closet among liquor bottles and teas. To keep them cool and quiet, the units are immersed directly in non-conductive oil, which absorbs the heat they give off and is pumped through tubes beneath Bathhouse’s hot tubs and hammams. Mining boilers, which cool the computers by pumping in cold water that comes back out at 170 °F, are now also being used at the site. A thermal battery stores excess heat for future use. Goodman says his spas aren’t saving energy by using bitcoin miners for heat, but they’re also not using any more than they would with conventional water heating. “I’m just inserting miners into that chain,” he says. Goodman isn’t the only one to see the potential in heating with crypto. In Finland, Marathon Digital Holdings turned fleets of bitcoin miners into a district heating system to warm the homes of 80,000 residents. HeatCore, an integrated energy service provider, DATA SOURCE: US CENTERS FOR DISEASE CONTROL AND PREVENTION The new device samples the air in real time, running the samples past a specialized biosensor every five minutes. The sensor has strands of genetic material called aptamers that were used to bind specifically to the virus. When that happens, it creates a detectable electrical change. The research, published in ACS Sensors in February, may help farmers contain future outbreaks. Part of the group’s work was devising a way to deliver airborne virus particles to the sensor. With bird flu, says Rajan Chakrabarty, a professor of energy, environmental, and chemical engineering at Washington University and lead author of the paper, “the bad apple is surrounded by a million or a billion good apples.” He adds, “The challenge was to take an airborne pathogen and get it into a liquid form to sample.” The team accomplished this by designing a microwave-size box that sucks in large volumes of air and spins it in a cyclone-like motion so that particles stick to liquid-coated walls. The process seamlessly produces a liquid drip that is pumped to the highly sensitive biosensor. Though the system is promising, its effectiveness in real-world conditions remains uncertain, says Sungjun Park, an associate professor of electrical and computer engineering at Ajou University in South Korea, who was not involved in the study. Dirt and other particles in farm air could hinder its performance. “The study does not extensively discuss the device’s performance in complex real-world air samples,” Park says. But Chakrabarty is optimistic that it will be commercially viable after further testing and is already working with a biotech company to scale it up. He hopes to develop a biosensor chip that detects multiple pathogens at once. ■ 4/2/25 2:1 PM JENNY KROIK The Download has used bitcoin mining to heat a commercial office building in China and to keep pools at a constant temperature for fish farming. This year it will begin a pilot project to heat seawater for desalination. On a smaller scale, bitcoin fans who also want some extra warmth can buy miners that double as space heaters. Crypto enthusiasts like Goodman think much more of this is coming—especially under the Trump administration, which has announced plans to create a bitcoin reserve. This prospect alarms environmentalists. The energy required for a single bitcoin transaction varies, but as of mid-March it was equivalent to the energy consumed by an average US household over 47.2 days, according to the Bitcoin Energy Consumption Index, run by the economist Alex de Vries. Among the various cryptocurrencies, bitcoin mining gobbles up the most energy by far. De Vries points out that others, like ethereum, have eliminated mining and implemented less energy-intensive algorithms. But bitcoin users resist any change to their currency, so de Vries is doubtful a shift away from mining will happen anytime soon. One key barrier to using bitcoin for heating, de Vries says, is that the heat can only be transported short distances before it dissipates. “I see this as something that is extremely niche,” he says. “It’s just not competitive, and you can’t make it work at a large scale.” The more renewable sources that are added to MJ25-front_thedownload.indd 9 electric grids to replace fossil fuels, the cleaner crypto mining will become. But even if bitcoin is powered by renewable energy, “that doesn’t make it sustainable,” says Kaveh Madani, director of the United Nations University Institute for Water, Environment, and Health. Mining burns through valuable resources that could otherwise be used to meet existing energy needs, Madani says. For Goodman, relaxing into bitcoin-heated water is a completely justifiable use of energy. 09 It soothes the muscles, calms the mind, and challenges current economic structures, all at the same time. ■ Carrie Klein is a freelance journalist based in New York City. 4/2/25 2:1 PM 10 The Download BY ARIEL ABERG-RIGER Changing channels AM radio has long served as a critical communication tool.

MJ25-front_thedownload.indd 12 On Thanksgiving weekend of 2013, Jeff Bezos, then Amazon’s CEO, took to 60 Minutes to make a stunning announcement: Amazon was a few years away from deploying drones that would deliver packages to homes in less than 30 minutes. It lent urgency to a problem that Parimal Kopardekar, director of the NASA Aeronautics Research Institute, had begun thinking about earlier that year. “How do you manage and accommodate largescale drone operations without overloading the air traffic control system?” Kopardekar, who goes by PK, recalls wondering. Busy managing all airplane takeoffs and landings, air traffic controllers clearly wouldn’t have the capacity to oversee the fleets of package-delivering drones Amazon was promising. The solution PK devised, which subsequently grew into a collaboration between federal agencies, researchers, and industry, is a system called unmannedaircraft-system traffic management, or UTM. Instead of verbally communicating with air traffic controllers, drone operators using UTM share their intended flight paths with each other via a cloud-based network. This highly scalable approach may finally open the skies to a host of commercial drone applications that have yet to materialize. Amazon Prime Air launched in 2022 but was put on hold after crashes at a testing facility, for example. On any given day, only 8,500 or so unmanned aircraft fly in US airspace, the vast majority of which are used for recreational purposes rather than for services like search and rescue missions, real estate inspections, video surveillance, or farmland surveys. One obstacle to wider use has been concern over possible midair drone-to-drone collisions. (Drones are typically restricted to airspace below 400 feet and their access to airports is limited, which significantly lowers the risk of drone-airplane collisions.) Under Federal Aviation Administration regulations, drones generally cannot fly beyond an operator’s visual line of sight, limiting flights to about a third of a mile. This prevents most collisions but also most use cases, such as delivering medication to a patient’s doorstep or dispatching a police drone to an active crime scene so first responders can better prepare before arriving. Now, though, drone operators are increasingly incorporating UTM into their flights. The system uses path planning algorithms, like those that run in Google Maps, to chart a course that considers not only weather and obstacles like buildings and trees but the flight paths of nearby drones. It’ll automatically reroute a flight before takeoff if another drone has reserved the same volume of airspace at the same time, making the new flight trajectory visible to subsequent pilots. Drones can then fly autonomously to and from their destination, and no air traffic controller is required. Over the past decade, NASA and industry have demonstrated to the FAA through a series of tests that drones can safely maneuver around each other by adhering to UTM. And last summer, the agency gave the go-ahead for multiple drone delivery companies using UTM to begin flying simultaneously in the same airspace above Dallas—a first in US aviation history. Drone operators without in-house UTM capabilities have also begun licensing UTM services from FAAapproved third-party providers. UTM only works if all participants abide by the same rules and agree to share data, and it’s enabled DOMINIC HART/NASA Air traffic control for drones is taking off Drones flying over Reno, Nevada, during one of NASA’s UTM tests in 2019. 4/2/25 2:1 PM The Download 13 3 Things BY CAIWEI CHEN COURTESY OF CAIWEI CHEN A new play about OpenAI a level of collaboration unusual for companies competing to gain a foothold in a young, hot field, notes Peter Sachs, head of airspace integration strategy at Zipline, a drone delivery company based in South San Francisco that’s approved to use UTM. “We all agree that we need to collaborate on the practical, behind-the-scenes nuts and bolts to make sure that this preflight deconfliction for drones works really well,” Sachs says. (“Strategic deconfliction” is the technical term for processes that minimize dronedrone collisions.) Zipline and the drone delivery companies Wing, Flytrex, and DroneUp all operate in the Dallas area and are racing to expand to more cities, yet they disclose where they’re flying to one another in the interest of keeping the airspace conflict-free. Greater adoption of UTM may be on the way. The FAA is expected to soon release a new rule called Part 108 that may allow operators to fly beyond visual line of sight if, among other requirements, they have some UTM capability, eliminating the need for the difficultto-obtain waiver the agency currently requires for these flights. To safely manage this additional drone traffic, drone companies will have to continue working together to keep their aircraft out of each other’s way.

MJ25-front_thedownload.indd 13 I recently saw Doomers, a new play by Matthew Gasda about the aborted 2023 coup at OpenAI, here represented by a fictional company called MindMesh. The action is set almost entirely in a meeting room; the first act follows executives immediately after the firing of company CEO Seth (a stand-in for Sam Altman), and the second re-creates the board negotiations that determined his fate. It’s a solid attempt to capture the zeitgeist of Silicon Valley’s AI frenzy and the world’s moral panic over artificial intelligence, but the rapid-fire, high-stakes exchanges mean it sometimes seems to get lost in its own verbosity. Themed dinner parties and culinary experiments The vastness of Chinese cuisine defies easy categorization, and even in a city with no shortage of options, I often find myself cooking—not just to recapture something closer to home, but to create a home unlike one that ever existed. Recently, I’ve been experimenting with a Chinese take on the charcuterie board—pairing toasted steamed buns, called mantou, with furu, a fermented tofu spread that is sharp, pungent, and full of umami. Sewing and copying my own clothes I started sewing three years ago, but only in the past year have I begun making clothes from scratch. As a lover of vintage fashion—especially ’80s silhouettes—I started out with old patterns I found on Etsy. But recently, I tried something new: copying a beloved dress I bought in a thrift store in Beijing years ago. Doing this is quite literally a process of reverseengineering—pinning the garment down, tracing its seams, deconstructing its logic, and rebuilding it. At times my brain feels like an old Mac hitting its GPU limit. But when it works, it feels like a small act of magic. It’s an exercise in certainty, the very thing that drew me to fashion in the first place—a chance to inhabit something that feels like an extension of myself. ■ Caiwei Chen is a reporter at MIT Technology Review focusing on China.

But these landforms, which circle the peaks of a mountain range that has vanished under the Indian Ocean, are far from inert. They’re the products of living processes—places where coral has grown toward the surface over hundreds of thousands of years. Shifting ocean currents have gradually pushed sand—made from broken-up bits of this same coral—into more than 1,000 other islands that poke above the surface. But these currents can also be remarkably transient, constructing new sandbanks or washing them away in a matter of weeks. In the coming decades, the daily lives of the half-million people who live on this archipelago—the world’s lowest-lying nation—will depend on finding ways to keep a solid foothold amid these shifting sands. More than 90% of the islands have experienced severe erosion, and climate change could make much of the country uninhabitable by the middle of the century. Off one atoll, just south of the Maldives’ capital, Malé, researchers are testing one way to capture sand in strategic locations—to grow islands, rebuild beaches, and protect coastal communities from sea-level rise. Swim 10 minutes out into the En’boodhoofinolhu Lagoon and you’ll find the Ramp Ring, an unusual structure made up of six toughskinned geotextile bladders. These submerged bags, part of a recent effort called the Growing Islands project, form a pair of parentheses separated by 90 meters (around 300 feet). The bags, each about two meters tall, were deployed in December 2024, and by February, underwater images showed that sand had climbed about a meter and a half up the surface of each one, demonstrating how passive structures can quickly replenish beaches and, in time, build a solid foundation for new land. “There’s just a ton of sand in there. It’s really looking good,” says Skylar Tibbits, an architect and founder of MJ25-front_thedownload.indd 14 the MIT Self-Assembly Lab, which is developing the project in partnership with the Malé-based climate tech company Invena. The Self-Assembly Lab designs material technologies that can be programmed to transform or “self-assemble” in the air or underwater, exploiting natural forces like gravity, wind, waves, and sunlight. Its creations include sheets of wood fiber that form into three-dimensional structures when splashed with water, which the researchers hope could be used for tool-free flat-pack furniture. Growing Islands is their largest-scale undertaking yet. Since 2017, the project has deployed 10 experiments in the Maldives, testing different materials, locations, and strategies, including inflatable structures and mesh nets. The Ramp Ring is many times larger than previous deployments and aims to overcome their biggest limitation. In the Maldives, the direction of the currents changes with the seasons. Past experiments have been able to capture only one seasonal flow, meaning they lie dormant for months of the year. By contrast, the Ramp Ring is “omnidirectional,” capturing sand year-round. “It’s basically a big ring, a big loop, and no matter which monsoon season and which wave direction, it accumulates sand in the same area,” Tibbits says. The approach points to a more sustainable way to protect the archipelago, whose growing population is supported by an economy that caters to 2 million annual tourists drawn by its white beaches and teeming coral reefs. Most of the country’s 187 inhabited islands have already had some form of human intervention to reclaim land or defend against erosion, such as concrete blocks, jetties, and breakwaters. Since the 1990s, dredging has become by far the most significant strategy. Boats equipped with high-power pumping systems vacuum up sand from one part of the seabed and spray it into a pile somewhere else. This temporary process allows resort developers and densely populated islands like Malé to quickly replenish beaches and build limitlessly customizable islands. But it also leaves behind dead zones where sand has been extracted—and plumes of sediment that cloud the water with a sort of choking marine smog. Last year, INVENA & SELF-ASSEMBLY LAB, MIT Building islands with ocean currents 4/3/25 :53 M The Ramp Ring, a set of six submerged bags, is deployed in the Maldives to test using current-driven sand to fight erosion. MJ25-front_thedownload.indd 15 the government placed a temporary ban on dredging to prevent damage to reef ecosystems, which were already struggling amid spiking ocean temperatures. Holly East, a geographer at the University of Northumbria, says Growing Islands’ structures offer an exciting alternative to dredging. But East, who is not involved in the project, warns that they must be sited carefully to avoid interrupting sand flows that already build up islands’ coastlines. To do this, Tibbits and Invena cofounder Sarah Dole are conducting long-term satellite analysis of the En’boodhoofinolhu Lagoon to understand how sediment flows move around atolls. On the basis of this work, the team is currently spinning out a predictive coastal intelligence platform called Littoral. The aim is for it to be “a global health monitoring system for sediment transport,” Dole says. It’s meant not only to show where beaches are losing sand but to “tell us where erosion is going to happen,” allowing government agencies and developers to know where new structures like Ramp Rings can best be placed. Growing Islands has been supported by the National Geographic Society, MIT, the Sri Lankan engineering group Sanken, and tourist resort developers. In 2023, it got a big bump from the US Agency for International Development: a $250,000 grant that funded the construction of the Ramp Ring deployment and would have provided opportunities to scale up the approach. But the termination of nearly all USAID contracts following the inauguration of President Trump means the project is looking for new partners. ■ Matthew Ponsford is a freelance reporter based in London. 4/2/25 2:1 PM 16 The Download Clamor: How Noise Took Over the World and How We Can Take It Back By Chris Berdik (W.W.

The first issue appeared in 1950 with scientific “SuspenStories” they “dared you to read.” The bimonthly issues that followed featured a gamut of what are now classic tropes of the genre: Martian invasions, murderous androids, glittering utopias, and all-female planets.

By Elissaveta M. Brandon Above: Arnhildur Pálmadóttir, an Icelandic architect, has designed buildings with half the typical carbon footprint and is hoping to use lava as a building material. Opposite: Set in 2150, her speculative film Lavaforming presents a fictional city built from molten lava. MJ25-front_profile.indd 18 Arnhildur Pálmadóttir was around three years old when she saw a red sky from her living room window. A volcano was erupting about 25 miles away from where she lived on the northeastern coast of Iceland. Though it posed no immediate threat, its ominous presence seeped into her subconscious, populating her dreams with streaks of light in the night sky. Fifty years later, these “gloomy, strange dreams,” as Pálmadóttir now describes them, have led to a career as an architect with an extraordinary mission: to harness molten lava and build cities out of it. Pálmadóttir today lives in Reykjavik, where she runs her own architecture studio, S.AP Arkitektar, and the Icelandic branch of the Danish architecture company Lendager, which specializes in reusing building materials. The architect believes the lava that flows from a single eruption could yield enough building material to lay the foundations of an entire city. She has been researching this possibility for more than five years as part of a project she calls Lavaforming. Together with her son and colleague Arnar Skarphéðinsson, she has identified three potential techniques: drill straight into magma pockets and extract the lava; channel molten lava into pre-dug COURTESY OF S.AP ARKITEKTAR The new hotness 3/2 /25 5:52 PM Profile trenches that could form a city’s foundations; or 3D-print bricks from molten lava in a technique similar to the way objects can be printed out of molten glass. Pálmadóttir and Skarphéðinsson first presented the concept during a talk at Reykjavik’s DesignMarch festival in 2022. This year they are producing a speculative film set in 2150, in an imaginary city called Eldborg. Their film, titled Lavaforming, follows the lives of Eldborg’s residents and looks back on how they learned to use molten lava as a building material. It will be presented at the Venice Biennale, a leading architecture festival, in May. Buildings and construction materials like concrete and steel currently contribute a staggering 37% of the world’s annual carbon dioxide emissions. Many architects are advocating for the use of natural or preexisting materials, but mixing earth and water into a mold is one thing; tinkering with 2,000 °F lava is another. Still, Pálmadóttir is piggybacking on research already being done in Iceland, which has 30 active volcanoes. Since 2021, eruptions have intensified in the Reykjanes Peninsula, which is close to the capital and to tourist hot spots like the Blue Lagoon. In 2024 alone, there were six volcanic eruptions in that area. This frequency has given volcanologists opportunities to study MJ25-front_profile.indd 19 19 how lava behaves after a volcano erupts. “We try to follow this beast,” says Gro Birkefeldt M. Pedersen, a volcanologist at the Icelandic Meteorological Office (IMO), who has consulted with Pálmadóttir on a few occasions. “There is so much going on, and we’re just trying to catch up and be prepared.” Pálmadóttir’s concept assumes that many years from now, volcanologists will be able to forecast lava flow accurately enough for cities to plan on using it in building. They will know when and where to dig trenches so that when a volcano erupts, the lava will flow into them and solidify into either walls or foundations. Today, forecasting lava flows is a complex science that requires remote sensing technology and tremendous amounts of computational power to run simulations on supercomputers. The IMO typically runs two simulations for every new eruption—one based on data from previous eruptions, and another based on additional data acquired shortly after the eruption (from various sources like specially outfitted planes). With every event, the team accumulates more data, which makes the simulations of lava flow more accurate. Pedersen says there is much research yet to be done, but she expects “a lot of advancement” in the next 10 years or so. 3/2 /25 5:52 PM Profile To design the speculative city of Eldborg for their film, Pálmadóttir and Skarphéðinsson used 3D-modeling software similar to what Pedersen uses for her simulations. The city is primarily built on a network of trenches that were filled with lava over the course of several eruptions, while buildings are constructed out of lava bricks. “We’re going to let nature design the buildings that will pop up,” says Pálmadóttir. The aesthetic of the city they envision will be less modernist and more fantastical—a bit “like [Gaudi’s] Sagrada Familia,” says Pálmadóttir. But the aesthetic output is not really the point; the architects’ goal is to galvanize architects today and spark an urgent discussion about the impact of climate change on our cities. She stresses the value of what can only be described as moonshot thinking. “I think it is important for architects not to be only in the present,” she told me. “Because if we are only in the present, working inside the system, we won’t change anything.” Pálmadóttir was born in 1972 in Húsavik, a town known as the whale-watching capital of Iceland. But she was more interested in space and technology and spent a lot of time flying with her father, a construction engineer who owned a small plane. She credits his job for the curiosity she developed about science and “how things were put together”—an inclination that proved useful later, when she started researching volcanoes. So was the fact that Icelanders “learn to live with volcanoes from birth.” At 21, she moved to Norway, where she spent seven years working in 3D visualization before returning to Reykjavik and enrolling in an architecture program at the Iceland University of the Arts. But things didn’t click until she moved to Barcelona for a master’s degree at the Institute for Advanced Architecture of Catalonia. “I remember being there and feeling, finally, like I was in the exact right place,” she says. Before, architecture had seemed like a commodity and architects like “slaves to investment companies,” she says. Now, it felt like a path with potential. She returned to Reykjavik in 2009 and worked as an architect until she founded S.AP (for “studio Arnhildur Pálmadóttir”) Arkitektar in 2018; her son started working with her in 2019 and officially joined her as an architect this year, after graduating from the Southern California Institute of Architecture. In 2021, the pair witnessed their first eruption up close, near the Fagradalsfjall volcano on the Reykjanes Peninsula. It was there that Pálmadóttir became aware of the sheer quantity of material coursing through the planet’s veins, and the potential to divert it into channels. Lava has already proved to be a strong, long-lasting building material—at least in its solid state. When it cools, it solidifies into volcanic rock like basalt or rhyolite. The type of rock depends on the composition of the lava, but basaltic lava—like the kind found in Iceland and Hawaii—forms one of the hardest rocks on Earth, which means that structures built from this type of lava would be durable and resilient. MJ25-front_profile.indd 20 For years, architects in Mexico, Iceland, and Hawaii (where lava is widely available) have built structures out of volcanic rock. But quarrying that rock is an energy-intensive process that requires heavy machines to extract, cut, and haul it, often across long distances, leaving a big carbon footprint. Harnessing lava in its molten state, however, could unlock new methods for sustainable construction. Jeffrey Karson, a professor emeritus at Syracuse University who specializes in volcanic activity and COURTESY OF S.AP ARKITEKTAR 20 3/2 /25 5:52 PM Lava has proved to be a strong, durable building material, at least in its solid state. To explore its potential,Pálmadóttir and Skarphéðinsson envision a city built on a network of trenches that have filled with lava over the course of several eruptions, while buildings are constructed with lava bricks. Profile 21 who cofounded the Syracuse University Lava Project, agrees that lava is abundant enough to warrant interest as a building material. To understand how it behaves, Karson has spent the past 15 years performing over a thousand controlled lava pours from giant furnaces. If we figure out how to build up its strength as it cools, he says, “that stuff has a lot of potential.” In his research, Karson found that inserting metal rods into the lava flow helps reduce the kind of uneven cooling that would lead to thermal cracking—and therefore makes the material stronger (a bit like rebar in concrete). Like glass and other molten materials, lava behaves differently depending on how fast it cools. When glass or lava cools slowly, crystals start forming, strengthening the material. Replicating this process—perhaps in a kiln—could slow down the rate of cooling and let the lava become stronger. This kind of controlled cooling is “easy to do on small things like bricks,” says Karson, so “it’s not impossible to make a wall.” Pálmadóttir is clear-eyed about the challenges before her. She knows the techniques she and Skarphéðinsson are exploring may not lead to anything tangible in their lifetimes, but they still believe that the ripple effect the projects could create in the architecture community is worth pursuing. Both Karson and Pedersen caution that more experiments are necessary to study this material’s potential. For Skarphéðinsson, that potential transcends the building industry. More than 12 years ago, Icelanders voted that the island’s natural resources, like its volcanoes and fishing waters, should be declared national property. That means any city built from lava flowing out of these volcanoes would be controlled not by deep-pocketed individuals or companies, but by the nation itself. (The referendum was considered illegal almost as soon as it was approved by voters and has since stalled.) For Skarphéðinsson, the Lavaforming project is less about the material than about the “political implications that get brought to the surface with this material.” “That is the change I want to see in the world,” he says. “It could force us to make radical changes and be a catalyst for something”—perhaps a social megalopolis where citizens have more say in how resources are used and profits are shared more evenly. Cynics might dismiss the idea of harnessing lava as pure folly. But the more I spoke with Pálmadóttir, the more convinced I became. It wouldn’t be the first time in modern history that a seemingly dangerous idea (for example, drilling into scalding pockets of underground hot springs) proved revolutionary. Once entirely dependent on oil, Iceland today obtains 85% of its electricity and heat from renewable sources. “[My friends] probably think I’m pretty crazy, but they think maybe we could be clever geniuses,” she told me with a laugh. Maybe she is a little bit of both. Elissaveta M. Brandon is a regular contributor to Fast Company and Wired.

These artists and musicians aren’t ceding their work to AI. Instead, they’re finding new ways to use it, injecting more friction, challenge, and serendipity into the creative process. By Will Douglas Heaven How AI can help supercharge creativity MJ25-feature_art.indd 24 Sometimes Lizzie Wilson shows up to a rave with her AI sidekick. One weeknight this past February, Wilson plugged her laptop into a projector that threw her screen onto the wall of a low-ceilinged loft space in East London. A small crowd shuffled in the glow of dim pink lights. Wilson sat down and started programming. Techno clicks and whirs thumped from the venue’s speakers. The audience watched, heads nodding, as Wilson tapped out code line by line on the projected screen—tweaking sounds, looping beats, pulling a face when she messed up. Wilson is a live coder. Instead of using purpose-built software like most electronic music producers, live coders create music by writing the code to generate it on the fly. It’s an improvised performance art known as algorave. “It’s kind of boring when you go to watch a show and someone’s just sitting there on their laptop,” she says. “You can enjoy the music, but there’s a performative aspect that’s missing. With live coding, everyone can see what it is that I’m typing. And when I’ve had my laptop crash, people really like that. They start cheering.” Taking risks is part of the vibe. And so Wilson likes to dial up her performances one more notch by riffing off what she calls a live-coding agent, a generative AI model that comes up with its own beats and loops to add to the mix. Often the model suggests sound combinations that Wilson hadn’t thought of. “You get these elements of surprise,” she says. “You just have to go for it.” Wilson, a researcher at the Creative Computing Institute at the University of the Arts London, is just one of many working on what’s known as co-creativity or more-than-human creativity. The idea is that AI can be used to inspire or critique creative projects, helping people make things that they would not have made by themselves. She and her colleagues built the live-coding agent to explore how artificial intelligence can be used to support human artistic endeavors—in Wilson’s case, musical improvisation. It’s a vision that goes beyond the promise of existing generative tools put out by companies like OpenAI and Google DeepMind. Those can automate a striking range of creative tasks and offer near-instant gratification—but at what cost? Some artists and researchers fear that such technology could turn us into passive consumers of yet more AI slop. 4/2/25 1 :11 M 25 Researcher Lizzie Wilson performs at an algorave in London. MJ25-feature_art.indd 25 4/2/25 1 :11 M 26 And so they are looking for ways to inject human creativity back into the process. The aim is to develop AI tools that augment our creativity rather than strip it from us—pushing us to be better at composing music, developing games, designing toys, and much more—and lay the groundwork for a future in which humans and machines create things together. Ultimately, generative models could offer artists and designers a whole new medium, pushing them to make things that couldn’t have been made before, and give everyone creative superpowers. Explosion of creativity There’s no one way to be creative, but we all do it. We make everything from memes to masterpieces, infant doodles to industrial designs. There’s a mistaken belief, typically among adults, that creativity is something you grow out of. But being creative—whether cooking, singing in the shower, or putting together super-weird TikToks— is still something that most of us do just for the fun of it. It doesn’t have to be high art or a world-changing idea (and yet it can be). Creativity is basic human behavior; it should be celebrated and encouraged. When generative text-to-image models like Midjourney, OpenAI’s DALL-E, and the popular opensource Stable Diffusion arrived, they sparked an explosion of what looked a lot like creativity. Millions of people were now able to create remarkable images of pretty much anything, in any style, with the click of a button. Text-to-video models came next. Now startups like Udio (see p. 36), are developing similar tools for music. Never before have the fruits of creation been within reach of so many. But for a number of researchers and artists, the hype around these tools has warped the idea of what creativity really is. “If I ask the AI to create something for me, that’s not me being creative,” says Jeba Rezwana, who works on co-creativity at Towson University in Maryland. “It’s a one-shot interaction: You click on it and it generates something and that’s it. You cannot say ‘I like this part, but maybe change something here.’ You cannot have a back-and-forth dialogue.” Rezwana is referring to the way most generative models are set up. You can give the tools feedback and ask them to have another go. But each new result is generated from scratch, which can make it hard to nail exactly what you want. As the filmmaker Walter Woodman put it last year after his art collective Shy Kids made a short film with OpenAI’s text-to-video MJ25-feature_art.indd 26 4/2/25 1 :11 M PREVIOUS SPREAD: JONATHAN REUS; DEVOLVER DIGITAL (OPPOSITE TOP); COURTESY OF MIKE COOK (PORTRAIT, OPPOSITE BOTTOM) 27 model for the first time: “Sora is a slot machine as to what you get back.” What’s more, the latest versions of some of these generative tools do not even use your submitted prompt as is to produce an image or video (at least not on their default settings). Before a prompt is sent to the model, the software edits it—often by adding dozens of hidden words—to make it more likely that the generated image will appear polished. “Extra things get added to juice the output,” says Mike Cook, a computational creativity researcher at King’s College London. “Try asking Midjourney to give you a bad drawing of something—it can’t do it.” These tools do not give you what you want; they give you what their designers think you want. All of which is fine if you just need a quick image and don’t care too much about the details, says Nick BryanKinns, also at the Creative Computing Institute: “Maybe you want to make a Christmas card for your family or a flyer for your community cake sale. These tools are great for that.” In short, existing generative models have made it easy to create, but they have not made it easy to be creative. And there’s a big difference between the two. For Cook, relying on such tools could in fact harm people’s creative development in the long run. “Although many of these creative AI systems are promoted as making creativity more accessible,” he wrote in a paper published last year, they might instead have “adverse effects on their users in terms of restricting their ability to innovate, ideate, and create.” Given how much generative models have been championed for putting creative abilities at everyone’s fingertips, the suggestion that they might in fact do the opposite is damning. He’s far from the only researcher worrying about the cognitive impact of these technologies. In February a team at Microsoft Research Cambridge published a report concluding that generative AI tools “can inhibit critical engagement with work and can potentially lead to long-term overreliance on the tool and diminished skill for independent problem-solving.” The researchers found that with the use of generative tools, people’s effort “shifts from task execution to task stewardship.” MJ25-feature_art.indd 27 Cook is concerned that generative tools don’t let you fail—a crucial part of learning new skills. We have a habit of saying that artists are gifted, says Cook. But the truth is that artists work at their art, developing skills over months and years. “If you actually talk to artists, they say, ‘Well, I got good by doing it over and over and over,’” he says. “But failure sucks. And we’re always looking at ways to get around that.” Generative models let us skip the frustration of doing a bad job. “Unfortunately, we’re removing the one thing that you have to do to develop creative skills for yourself, which is fail,” says Cook. “But absolutely nobody wants to hear that.” Surprise me Mike Cook, a computational creativity researcher, used an AI tool to design a new level for the game Disc Room (opposite, above), in which players navigate a room of moving buzz saws. The result was a room where none of the discs actually moved (below). And yet it’s not all bad news. Artists and researchers are buzzing at the ways generative tools could empower creators, pointing them in surprising new directions and steering them away from dead ends. Cook thinks the real promise of AI will be to help us get better at what we want to do rather than doing it for us. For that, he says, we’ll need to create new tools, different from the ones we have now. “Using Midjourney does not do anything for me—it doesn’t change anything about me,” he says. “And I think that’s a wasted opportunity.” Ask a range of researchers studying creativity to name a key part of the creative process and many will say: reflection. It’s hard to define exactly, but reflection is a particular type of focused, deliberate thinking. It’s what happens when a new idea hits you. Or when an assumption you had turns out to be wrong and you need to rethink your approach. It’s the opposite of a one-shot interaction. Looking for ways that AI might support or encourage reflection—asking it to throw new ideas into the mix or challenge ideas you already hold—is a common thread across co-creativity research. If generative tools like DALL-E make creation frictionless, the aim here is to add friction back in. “How can we make art without friction?” asks Elisa Giaccardi, who studies design at the Polytechnic University of Milan in Italy. “How can we engage in a truly creative process without material that pushes back?” 4/2/25 1 :11 M Take Wilson’s live-coding agent. She claims that it pushes her musical improvisation in directions she might not have taken by herself. Trained on public code shared by the wider live-coding community, the model suggests snippets of code that are closer to other people’s styles than her own. This makes it more likely to produce something unexpected. “Not because you couldn’t produce it yourself,” she says. “But the way the human brain works, you tend to fall back on repeated ideas.” Last year, Wilson took part in a study run by BryanKinns and his colleagues in which they surveyed six experienced musicians as they used a variety of generative models to help them compose a piece of music. The researchers wanted to get a sense of what kinds of interactions with the technology were useful and which were not. The participants all said they liked it when the models made surprising suggestions, even when those were the result of glitches or mistakes. Sometimes the results were simply better. Sometimes the process felt fresh and exciting. But a few people struggled with giving up control. It was hard to direct the models to produce specific results or to repeat results that the musicians had liked. “In some ways it’s the same as being in a band,” says Bryan-Kinns. “You need to have that sense of risk and a sense of surprise, but you don’t want it totally random.” Alternative designs Cook comes at surprise from a different angle: He coaxes unexpected insights out of AI tools that he has developed to co-create video games. One of his tools, Puck, which was first released in 2022, generates designs for simple shape-matching puzzle games like Candy Crush or Bejeweled. A lot of Puck’s designs are experimental and clunky—don’t expect it to come up with anything you are ever likely to play. But that’s not the point: Cook uses Puck—and a newer tool called Pixie—to explore what kinds of interactions people might want to have with a co-creative tool. Pixie can read computer code for a game and tweak certain lines to come up with alternative designs. Not long ago, Cook was working on a copy of a popular game called Disc Room, in which players have to cross MJ25-feature_art.indd 28 Researcher Anne Arzberger developed experimental AI tools to come up with genderneutral toy designs (opposite). a room full of moving buzz saws. He asked Pixie to help him come up with a design for a level that skilled and unskilled players would find equally hard. Pixie designed a room where none of the discs actually moved. Cook laughs: It’s not what he expected. “It basically turned the room into a minefield,” he says. “But I thought it was really interesting. I hadn’t thought of that before.” Pushing back on assumptions, or being challenged, is part of the creative process, says Anne Arzberger, a researcher at the Delft University of Technology in the Netherlands. “If I think of the people I’ve collaborated with best, they’re not the ones who just said ‘Yes, great’ to every idea I brought forth,” she says. “They were really critical and had opposing ideas.” She wants to build tech that provides a similar sounding board. As part of a project called Creating Monsters, Arzberger developed two experimental AI tools that help designers find hidden biases in their designs. “I was interested in ways in which I could use this technology to access information that would otherwise be difficult to access,” she says. For the project, she and her colleagues looked at the problem of designing toy figures that would be gender neutral. She and her colleagues (including Giaccardi) used Teachable Machine, a web app built by Google researchers in 2017 that makes it easy to train your own machine-learning model to classify different inputs, such as images. They trained this model with a few dozen images that Arzberger had labeled as being masculine, feminine, or gender neutral. Arzberger then asked the model to identify the genders of new candidate toy designs. She found that quite a few designs were judged to be feminine even when she had tried to make them gender neutral. She felt that her views of the world—her own hidden biases—were being exposed. But the tool was often right: It challenged her assumptions and helped the team improve the designs. The same approach could be used to assess all sorts of design characteristics, she says. Arzberger then used a second model, a version of a tool made by the generative image and video startup Runway, to come up with gender-neutral toy designs of its own. First the researchers trained the model to generate and classify designs for male- and female-looking COURTESY OF ANNE ARZBERGER 28 4/2/25 1 :11 M 29 MJ25-feature_art.indd 29 4/2/25 1 :11 M toys. They could then ask the tool to find a design that was exactly midway between the male and female designs it had learned. Generative models can give feedback on designs that human designers might miss by themselves, she says: “We can really learn something.” Taking control The history of technology is full of breakthroughs that changed the way art gets made, from recipes for vibrant new paint colors to photography to synthesizers. In the 1960s, the Stanford researcher John Chowning spent years working on an esoteric algorithm that could manipulate the frequencies of computer-generated sounds. Stanford licensed the tech to Yamaha, which built it into its synthesizers—including the DX7, the cool new sound behind 1980s hits such as Tina Turner’s “The Best,” A-ha’s “Take On Me,” and Prince’s “When Doves Cry.” Bryan-Kinns is fascinated by how artists and designers find ways to use new technologies. “If you talk to artists, most of them don’t actually talk about these AI generative models as a tool—they talk about them as a material, like an artistic material, like a paint or something,” he says. “It’s a different way of thinking about what the AI is doing.” He highlights the way some people are pushing the technology to do weird things it wasn’t designed to do. Artists often appropriate or misuse these kinds of tools, he says. Bryan-Kinns points to the work of Terence Broad, another colleague of his at the Creative Computing Institute, as a favorite example. Broad employs techniques like network bending, which involves inserting new layers into a neural network to produce glitchy visual effects in generated images, and generating images with a model trained on no data, which produces almost Rothko-like abstract swabs of color. But Broad is an extreme case. Bryan-Kinns sums it up like this: “The problem is that you’ve got this gulf between the very commercial generative tools that produce super-high-quality outputs but you’ve got very little control over what they do—and then you’ve got this other end where you’ve got total control over what they’re doing but the barriers to use are high because MJ25-feature_art.indd 30 Researcher Terence Broad creates dynamic images using a model trained on no data, which produces almost Rothko-like abstract color fields (opposite). you need to be somebody who’s comfortable getting under the hood of your computer.” “That’s a small number of people,” he says. “It’s a very small number of artists.” Arzberger admits that working with her models was not straightforward. Running them took several hours, and she’s not sure the Runway tool she used is even available anymore. Bryan-Kinns, Arzberger, Cook, and others want to take the kinds of creative interactions they are discovering and build them into tools that can be used by people who aren’t hardcore coders. Finding the right balance between surprise and control will be hard, though. Midjourney can surprise, but it gives few levers for controlling what it produces beyond your prompt. Some have claimed that writing prompts is itself a creative act. “But no one struggles with a paintbrush the way they struggle with a prompt,” says Cook. Faced with that struggle, Cook sometimes watches his students just go with the first results a generative tool gives them. “I’m really interested in this idea that we are priming ourselves to accept that whatever comes out of a model is what you asked for,” he says. He is designing an experiment that will vary single words and phrases in similar prompts to test how much of a mismatch people see between what they expect and what they get. But it’s early days yet. In the meantime, companies developing generative models typically emphasize results over process. “There’s this impressive algorithmic progress, but a lot of the time interaction design is overlooked,” says Rezwana. For Wilson, the crucial choice in any co-creative relationship is what you do with what you’re given. “You’re having this relationship with the computer that you’re trying to mediate,” she says. “Sometimes it goes wrong, and that’s just part of the creative process.” When AI gives you lemons—make art. “Wouldn’t it be fun to have something that was completely antagonistic in a performance—like, something that is actively going against you—and you kind of have an argument?” she says. “That would be interesting to watch, at least.” Will Douglas Heaven is senior editor for AI at MIT Technology Review.

BY ILLUSTRATION MJ25-feature_Q&A.indd 33 Bryan Gardiner Tom Humberstone Americans don’t agree on much these days. Yet even at a time when consensus reality seems to be on the verge of collapse, there remains at least one quintessentially modern value we can all still get behind: creativity. We teach it, measure it, envy it, cultivate it, and endlessly worry about its death. And why wouldn’t we? Most of us are taught from a young age that creativity is the key to everything from finding personal fulfillment to achieving career success to solving the world’s thorniest problems. Over the years, we’ve built creative industries, creative spaces, and creative cities and populated them with an entire class of people known simply as “creatives.” We read thousands of books and articles each year that teach us how to unleash, unlock, foster, boost, and hack our own personal creativity. Then we read even more to learn how to manage and protect this precious resource. Given how much we obsess over it, the concept of creativity can feel like something that has always existed, a thing philosophers and artists have pondered and debated throughout the ages. While it’s a reasonable assumption, it’s one that turns out to be very wrong. As Samuel Franklin explains in his recent book, The Cult of Creativity, the first known written use of creativity didn’t actually occur until 1875, “making it an infant as far as words go.” What’s more, he writes, before about 1950, “there were approximately zero articles, books, essays, treatises, odes, classes, encyclopedia entries, or anything of the sort dealing explicitly with the subject of ‘creativity.’” This raises some obvious questions. How exactly did we go from never talking about creativity to always talking about it? What, if anything, distinguishes creativity from other, older words, like ingenuity, cleverness, imagination, and artistry? Maybe most important: How did everyone from kindergarten teachers to mayors, CEOs, designers, engineers, activists, and starving artists come to believe that creativity isn’t just good—personally, socially, economically—but the answer to all life’s problems? Thankfully, Franklin offers some potential answers in his book. A historian and design researcher at the Delft University of Technology in the Netherlands, he argues that the concept of creativity as we now know it emerged during the post–World War II era in America as a kind of cultural salve—a way to ease the tensions and anxieties caused by increasing conformity, bureaucracy, and suburbanization. “Typically defined as a kind of trait or process vaguely associated with artists and geniuses but theoretically possessed by anyone and applicable to any field, [creativity] provided a way to unleash individualism within order,” he writes, “and revive the spirit of the lone inventor within the maze of the modern corporation.” I spoke to Franklin about why we continue to be so fascinated by creativity, how Silicon Valley became the supposed epicenter of it, and what role, if any, technologies like AI might have in reshaping our relationship with it. 3/2 /25 5:55 PM 34 Below: Brainstorming, a new method for encouraging creative thinking, swept corporate America in the 1950s. A response to pressure for new products and new ways of marketing them, as well as a panic over conformity, it inspired passionate debate about whether true creativity should be an individual affair or could be systematized for corporate use. Opposite: Staff members at the University of California’s Institute of Personality Assessment and Research simulate a situational procedure involving group interaction, called the Bingo Test. Researchers of the 1950s hoped to learn how factors in people’s lives and environments shaped their creative aptitude. I’m curious what your personal relationship to creativity was growing up. What made you want to write a book about it? When did you start thinking about creativity as a kind of cult—one that we’re all a part of? already eminent in fields that were deemed creative—writers like Truman Capote and Norman Mailer, architects like Louis Kahn and Eero Saarinen—and just give them a battery of cognitive and psychoanalytic tests and then write up the results. This was mostly done by an outfit called the Institute of Personality Assessment and Research (IPAR) at Berkeley. Frank Barron and Don MacKinnon were the two biggest researchers in that group. Another way psychologists went about it was to say, all right, that’s not going to be Like a lot of kids, I grew up thinking that creativity was this inherently good thing. For me—and I imagine for a lot of other people who, like me, weren’t particularly athletic or good at math and science— being creative meant you at least had some future in this world, even if it wasn’t clear what that future would entail. By the time I got into college and beyond, the conventional wisdom among the TED Talk register of thinkers—people like Daniel Pink and Richard Florida—was that creativity was actually the most important trait to have for the future. Basically, the creative people were going to inherit the Earth, and society desperately needed them if we were going to solve all of these compounding problems in the world. On the one hand, as someone who liked to think of himself as creative, it was hard not to be flattered by this. On the other hand, it all seemed overhyped to me. What was being sold as the triumph of the creative class wasn’t actually resulting in a more inclusive or creative world order. What’s more, some of the values embedded in what I call the cult of creativity seemed increasingly problematic— specifically, the focus on self-realization, doing what you love, and following your passion. Don’t get me wrong—it’s a beautiful vision, and I saw it work out for some people. But I also started to feel like it was just a cover for what was, economically speaking, a pretty bad turn of events for many people. Nowadays, it’s quite common to bash the “follow your passion,” “hustle culture” idea. But back when I started this project, the whole move-fast-and-break-things, disrupter, innovation-economy stuff was very much unquestioned. In a way, the idea for the book came from recognizing that creativity was playing this really interesting role in connecting two worlds: this world of innovation and entrepreneurship and this more soulful, bohemian side of our culture. I wanted to better understand the history of that relationship. MJ25-feature_Q&A.indd 34 Similar to something like the “cult of domesticity,” it was a way of describing a historical moment in which an idea or value system achieves a kind of broad, uncritical acceptance. I was finding that everyone was selling stuff based on the idea that it boosted your creativity, whether it was a new office layout, a new kind of urban design, or the “Try these five simple tricks” type of thing. You start to realize that nobody is bothering to ask, “Hey, uh, why do we all need to be creative again? What even is this thing, creativity?” It had become this unimpeachable value that no one, regardless of what side of the political spectrum they fell on, would even think to question. That, to me, was really unusual, and I think it signaled that something interesting was happening. Your book highlights midcentury efforts by psychologists to turn creativity into a quantifiable mental trait and the “creative person” into an identifiable type. How did that play out? The short answer is: not very well. To study anything, you of course need to agree on what it is you’re looking at. Ultimately, I think these groups of psychologists were frustrated in their attempts to come up with scientific criteria that defined a creative person. One technique was to go find people who were practical for coming up with a good scientific standard. We need numbers, and lots and lots of people to certify these creative criteria. This group of psychologists theorized that something called “divergent thinking” was a major component of creative accomplishment. You’ve heard of the brick test, where you’re asked to come up with many creative uses for a brick in a given amount of time? They basically gave a version of that test to Army officers, schoolchildren, rank-and-file engineers at General Electric, all kinds of people. It’s tests like those that ultimately became stand-ins for what it means to be “creative.” Are they still used? When you see a headline about AI making people more creative, or actually being 3/2 /25 5:55 PM 35 engineer working for a large R&D lab of a brick-and-mortar manufacturing corporation and instead raise up the idea of a rebellious counterculture type tinkering in a garage making weightless products and experiences. That, I think, has saved it from a lot of public scrutiny. Up until recently, we’ve tended to think of creativity as a human trait, maybe with a few exceptions from the rest of the animal world. Is AI changing that? IMAGES COURTESY INSTITUTE OF PERSONALITY AND SOCIAL RESEARCH, UNIVERSITY OF CALIFORNIA, BERKELEY/THE MONACELLI PRESS The question of “Can machines be ‘truly creative’?” is not that interesting, but the questions of “Can they be wise, honest, caring?” are more important. more creative than humans, the tests they are basing that assertion on are almost always some version of a divergent thinking test. It’s highly problematic for a number of reasons. Chief among them is the fact that these tests have never been shown to have predictive value—that’s to say, a third grader, a 21-year-old, or a 35-year-old who does really well on divergent thinking tests doesn’t seem to have any greater likelihood of being successful in creative pursuits. The whole point of developing these tests in the first place was to both identify and predict creative people. None of them have been shown to do that. Reading your book, I was struck by how vague and, at times, contradictory the concept of “creativity” was from the beginning. You characterize that as “a feature, not a bug.” How so? Ask any creativity expert today what they mean by “creativity,” and they’ll tell you it’s the ability to generate something new and useful. That something could be an idea, a product, an academic paper—whatever. But the focus on novelty has remained an aspect of creativity from the beginning. It’s also what distinguishes it from other similar words, like imagination or cleverness. But you’re right: Creativity is a flexible enough MJ25-feature_Q&A.indd 35 concept to be used in all sorts of ways and to mean all sorts of things, many of them contradictory. I think I write in the book that the term may not be precise, but that it’s vague in precise and meaningful ways. It can be both playful and practical, artsy and technological, exceptional and pedestrian. That was and remains a big part of its appeal. Is that emphasis on novelty and utility a part of why Silicon Valley likes to think of itself as the new nexus for creativity? Absolutely. The two criteria go together. In techno-solutionist, hypercapitalist milieus like Silicon Valley, novelty isn’t any good if it’s not useful (or at least marketable), and utility isn’t any good (or marketable) unless it’s also novel. That’s why they’re often dismissive of boring-but-important things like craft, infrastructure, maintenance, and incremental improvement, and why they support art—which is traditionally defined by its resistance to utility—only insofar as it’s useful as inspiration for practical technologies. At the same time, Silicon Valley loves to wrap itself in “creativity” because of all the artsy and individualist connotations. It has very self-consciously tried to distance itself from the image of the buttoned-down When people started defining creativity in the ’50s, the threat of computers automating white-collar work was already underway. They were basically saying, okay, rational and analytical thinking is no longer ours alone. What can we do that the computers can never do? And the assumption was that humans alone could be “truly creative.” For a long time, computers didn’t do much to really press the issue on what that actually meant. Now they’re pressing the issue. Can they do art and poetry? Yes. Can they generate novel products that also make sense or work? Sure. I think that’s by design. The kinds of LLMs that Silicon Valley companies have put forward are meant to appear “creative” in those conventional senses. Now, whether or not their products are meaningful or wise in a deeper sense, that’s another question. If we’re talking about art, I happen to think embodiment is an important element. Nerve endings, hormones, social instincts, morality, intellectual honesty— those are not things essential to “creativity” necessarily, but they are essential to putting things out into the world that are good, and maybe even beautiful in a certain antiquated sense. That’s why I think the question of “Can machines be ‘truly creative’?” is not that interesting, but the questions of “Can they be wise, honest, caring?” are more important if we’re going to be welcoming them into our lives as advisors and assistants. This interview is based on two conversations and has been edited and condensed for clarity. Bryan Gardiner is a writer based in Oakland, California. 3/2 /25 5:55 PM 36 Replication and creation Artificial intelligence was barely a term in 1956, when top scientists from the field of computing arrived at Dartmouth College for a summer conference. The computer scientist John McCarthy had coined the phrase in the funding proposal for the event, a gathering to work through how to build machines that could use language, solve problems like humans, and improve themselves. But it was a good choice, one that captured the organizers’ founding premise: Any feature of human intelligence could “in principle be so precisely described that a machine can be made to simulate it.” In their proposal, the group had listed several “aspects of the artificial intelligence problem.” The last item on their list, and in hindsight perhaps the most difficult, was building a machine that could exhibit creativity and originality. At the time, psychologists were grappling with how to define and measure creativity in humans. The prevailing theory—that creativity was a product of intelligence and high IQ—was fading, but psychologists weren’t sure what to replace it with. The Dartmouth organizers had one of their own. “The difference between creative thinking and unimaginative competent thinking lies in the injection of some randomness,” they wrote, adding that such randomness “must be guided by intuition to be efficient.” Nearly 70 years later, following a number of boom-and-bust cycles in the field, we now have AI models that more or less follow that recipe. While large language models that generate text have exploded in the last three years, a different type of AI, based on what are called diffusion models, is having an unprecedented impact on creative domains. By transforming random noise into coherent patterns, diffusion models can generate new images, videos, or speech, guided by text prompts or other input data. The best ones can create outputs indistinguishable from the work of people, as well as bizarre, surreal results that feel distinctly nonhuman. Now these models are marching into a creative field that is arguably more vulnerable to disruption than any other: music. AI-generated creative works—from orchestra performances to heavy metal—are poised to suffuse our lives more thoroughly than any other product of AI has done yet. The songs are likely to blend into our streaming platforms, party and wedding playlists, soundtracks, and more, whether or not we notice who (or what) made them. For years, diffusion models have stirred debate in the visual-art world about whether what they produce reflects true creation or mere replication. Now this debate has come for music, an art form that is deeply embedded in our experiences, memories, and social lives. Music models can now create songs capable of eliciting real emotional responses, presenting a stark example of how difficult it’s becoming to define authorship and originality in the age of AI. The courts are actively grappling with this murky territory. Major record labels are suing the top AI music generators, alleging that diffusion models do little more than replicate human art without compensation to artists. The model makers counter that their tools are made to assist in human creation. In deciding who is right, we’re forced to think hard about our own human creativity. Is creativity, whether in artificial neural networks or biological ones, merely the result of vast statistical learning and drawn connections, with a sprinkling of randomness? If so, then authorship is a slippery concept. If not—if there is some distinctly human element to creativity—what is it? What does it mean to be moved by something without a human creator? I had to wrestle with these questions the first time I heard an AI-generated song that was genuinely fantastic—it was unsettling to know that someone merely wrote a prompt and clicked “Generate.” That predicament is coming soon for you, too. Diffusion AI models, and the machine-made music they create, are complicating our ability to define authorship and originality. By James O’Donnell MJ25-feature_music.indd 36 Illustrations by Stuart Bradford 4/2/25 1 :14 M 37 MJ25-feature_music.indd 37 4/2/25 1 :14 M 38 Making connections After the Dartmouth conference, its participants went off in different research directions to create the foundational technologies of AI. At the same time, cognitive scientists were following a 1950 call from J.P. Guilford, president of the American Psychological Association, to tackle the question of creativity in human beings. They came to a definition, first formalized in 1953 by the psychologist Morris Stein in the Journal of Psychology: Creative works are both novel, meaning they present something new, and useful, meaning they serve some purpose to someone. Some have called for “useful” to be replaced by “satisfying,” and others have pushed for a third criterion: that creative things are also surprising. Later, in the 1990s, the rise of functional magnetic resonance imaging made it possible to study more of the neural mechanisms underlying creativity in many fields, including music. Computational methods in the past few years have also made it easier to map out the role that memory and associative thinking play in creative decisions. What has emerged is less a grand unified theory of how a creative idea originates and unfolds in the brain and more an ever-growing list of powerful observations. We can first divide the human creative process into phases, including an ideation or proposal step, followed by a more critical and evaluative step that looks for merit in ideas. A leading theory on what guides these two phases is called the associative theory of creativity, which posits that the most creative people can form novel connections between distant concepts. “It could be like spreading activation,” says Roger Beaty, a researcher who leads the Cognitive Neuroscience of Creativity Laboratory at Penn State. “You think of one thing; it just kind of activates related concepts to whatever that one concept is.” These connections often hinge specifically on semantic memory, which stores concepts and facts, as opposed to episodic memory, which stores memories from a particular time and place. Recently, more sophisticated computational models have been used to study how people make connections between concepts across great “semantic distances.” For example, the word apocalypse is more closely related to nuclear power than to celebration. Studies have shown that highly creative people may perceive very semantically distinct concepts as close together. Artists have been found to generate word associations across greater distances than non-artists. Other research has supported the idea that creative people have “leaky” attention—that is, they often notice information that might not be particularly relevant to their immediate task. Neuroscientific methods for evaluating these processes do not suggest that creativity unfolds in a particular area of the brain. “Nothing in the brain produces creativity like a gland secretes a hormone,” Dean Keith Simonton, a leader in creativity research, wrote in the Cambridge Handbook of the Neuroscience of Creativity. The evidence instead points to a few dispersed networks of activity during creative thought, Beaty says—one to support the initial generation of ideas through associative thinking, another involved in identifying promising ideas, and another for evaluation and modification. A new study, led by researchers at Harvard Medical School and published in February, suggests that creativity might even involve the suppression of particular brain networks, like ones involved in self-censorship. So far, machine creativity— if you can call it that—looks quite different. Though at the time of the Dartmouth conference AI researchers were interested in machines inspired by human brains, that focus had shifted by the time diffusion models were invented, about a decade ago. The best clue to how they work is in the name. If you dip a paintbrush loaded with red ink into a glass jar of water, the ink will diffuse and swirl into the water seemingly at random, eventually yielding a pale pink liquid. Diffusion models simulate this process in reverse, reconstructing legible forms from randomness. For a sense of how this works for images, picture a photo of an elephant. To train the model, you make a copy of the photo, adding a layer of random black-and-white static on top. Make a second copy and add a bit more, and so on hundreds of times until the last image is pure static, with no elephant in sight. For each image in between, a statistical model predicts how much of the image is noise and how much is really the elephant. It compares its guesses with the right answers and learns from its mistakes. Over millions of these examples, the model gets better at “de-noising” the images and connecting these patterns to descriptions like “male Borneo elephant in an open field.” Now that it’s been trained, generating a new image means reversing this process. If you give the model a prompt, like “a The results of Udio and Suno so far suggest there’s a sizable audience of people who may not care whether the music they listen to is made by humans or machines. MJ25-feature_music.indd 38 4/2/25 1 :14 M 39 happy orangutan in a mossy forest,” it generates an image of random white noise and works backward, using its statistical model to remove bits of noise step by step. At first, rough shapes and colors appear. Details come after, and finally (if it works) an orangutan emerges, all without the model “knowing” what an orangutan is. Musical images The approach works much the same way for music. A diffusion model does not “compose” a song the way a band might, starting with piano chords and adding vocals and drums. Instead, all the elements are generated at once. The process hinges on the fact that the many complexities of a song can be depicted visually in a single waveform, representing the amplitude of a sound wave plotted against time. Think of a record player. By traveling along a groove in a piece of vinyl, a needle mirrors the path of the sound waves engraved in the material and transmits it into a signal for the speaker. The speaker simply pushes out air in these patterns, generating sound waves that convey the whole song. From a distance, a waveform might look as if it just follows a song’s volume. But if you were to zoom in closely enough, you could see patterns in the spikes and valleys, like the 49 waves per second for a bass guitar playing a low G. A waveform contains the summation of the frequencies of all different instruments and textures. “You see certain shapes start taking place,” says David Ding, cofounder of the AI music company Udio, “and that kind of corresponds to the broad melodic sense.” Since waveforms, or similar charts called spectrograms, can be treated like images, you can create a diffusion model out of them. A model is fed millions of clips of existing songs, each labeled with a description. To generate a new song, it starts with pure random noise and works backward to create a new waveform. The path it takes to do so is shaped by what words someone puts into the prompt. Ding worked at Google DeepMind for five years as a senior research engineer on diffusion models for images and videos, but he left to found Udio, based in New York, in 2023. The company and its competitor Suno, based in Cambridge, Massachusetts, are now leading the race for music generation models. Both aim to build AI tools that enable nonmusicians to make music. Suno MJ25-feature_music.indd 39 is larger, claiming more than 12 million users, and raised a $125 million funding round in May 2024. The company has partnered with artists including Timbaland. Udio raised a seed funding round of $10 million in April 2024 from prominent investors like Andreessen Horowitz as well as musicians Will.i.am and Common. The results of Udio and Suno so far suggest there’s a sizable audience of people who may not care whether the music they listen to is made by humans or machines. Suno has artist pages for creators, some with large followings, who generate songs entirely with AI, often accompanied by AI-generated images of the artist. These creators are not musicians in the conventional sense but skilled prompters, creating work that can’t be attributed to a single composer or singer. In this emerging space, our normal definitions of authorship—and our lines between creation and replication—all but dissolve. The music industry is pushing back. Both companies were sued by major record labels in June 2024, and the lawsuits are ongoing. The labels, including Universal and Sony, allege that the AI models have been trained on copyrighted music “at an almost unimaginable scale” and generate songs that “imitate the qualities of genuine human sound recordings” (the case against Suno cites one ABBAadjacent song called “Prancing Queen,” for example). Suno did not respond to requests for comment on the litigation, but in a statement responding to the case posted on Suno’s blog in August, CEO Mikey Shulman said the company trains on music found on the open internet, which “indeed contains copyrighted materials.” But, he argued, “learning is not infringing.” A representative from Udio said the company would not comment on pending litigation. At the time of the lawsuit, Udio released a statement mentioning that its model has filters to ensure that it “does not reproduce copyrighted works or artists’ voices.” Complicating matters even further is guidance from the US Copyright Office, released in January, that says AI-generated works can be copyrighted if they involve a considerable amount of human input. A month later, an artist in New York received what might be the first copyright for a piece of visual art made with the help of AI. The first song could be next. 4/2/25 1 :14 M 40 Novelty and mimicry These legal cases wade into a gray area similar to one explored by other court battles unfolding in AI. At issue here is whether training AI models on copyrighted content is allowed, and whether generated songs unfairly copy a human artist’s style. But AI music is likely to proliferate in some form regardless of these court decisions; YouTube has reportedly been in talks with major labels to license their music for AI training, and Meta’s recent expansion of its agreements with Universal Music Group suggests that licensing for AI-generated music might be on the table. If AI music is here to stay, will any of it be any good? Consider three factors: the training data, the diffusion model itself, and the prompting. The model can only be as good as the library of music it learns from and the descriptions of that music, which must be complex to capture it well. A model’s architecture then determines how well it can use what’s been learned to generate songs. And the prompt you feed into the model—as well as the extent to which the model “understands” what you mean by “turn down that saxophone,” for example—is pivotal too. Arguably the most important issue is the first: How extensive and diverse is the training data, and how well is it labeled? Neither Suno nor Udio has disclosed what music has gone into its training set, though these details will likely have to be disclosed during the lawsuits. Udio says the way those songs are labeled is essential to the model. “An area of active research for us is: How do we get more and more refined descriptions of music?” Ding says. A basic description would identify the genre, but then you could also say whether a song is moody, uplifting, or calm. More technical descriptions might mention a two-five-one chord progression or a specific scale. Udio says it does this through a combination of machine and human labeling. “Since we want to target a broad range of target users, that also means that we need a broad range of music annotators,” he says. “Not just people with music PhDs who can describe the music on a very technical level, but also music enthusiasts who have their own informal vocabulary for describing music.” Competitive AI music generators must also learn from a constant supply of new songs made by people, or else their outputs will be stuck in time, sounding stale and dated. For this, today’s MJ25-feature_music.indd 40 AI-generated music relies on human-generated art. In the future, though, AI music models may train on their own outputs, an approach being experimented with in other AI domains. Because models start with a random sampling of noise, they are nondeterministic; giving the same AI model the same prompt will result in a new song each time. That’s also because many makers of diffusion models, including Udio, inject additional randomness through the process—essentially taking the waveform generated at each step and distorting it ever so slightly in hopes of adding imperfections that serve to make the output more interesting or real. The organizers of the Dartmouth conference themselves recommended such a tactic back in 1956. According to Udio cofounder and chief operating officer Andrew Sanchez, it’s this randomness inherent in generative AI programs that comes as a shock to many people. For the past 70 years, computers have executed deterministic programs: Give the software an input and receive the same response every time. “Many of our artists partners will be like, ‘Well, why does it do this?’” he says. “We’re like, well, we don’t really know.” The generative era requires a new mindset, even for the companies creating it: that AI programs can be messy and inscrutable. Is the result creation or simply replication of the training data? Fans of AI music told me we could ask the same question about human creativity. As we listen to music through our youth, neural mechanisms for learning are weighted by these inputs, and memories of these songs influence our creative outputs. In a recent study, Anthony Brandt, a composer and professor of music at Rice University, pointed out that both humans and large language models use past experiences to evaluate possible future scenarios and make better choices. Indeed, much of human art, especially in music, is borrowed. This often results in litigation, with artists alleging that a song was copied or sampled without permission. Some artists suggest that diffusion models should be made more transparent, so we could know that a given song’s inspiration is three parts David Bowie and one part Lou Reed. Udio says there is ongoing research to achieve this, but right now, no one can do it reliably. 4/2/25 1 :14 M 41 For great artists, “there is that combination of novelty and influence that is at play,” Sanchez says. “And I think that that’s something that is also at play in these technologies.” But there are lots of areas where attempts to equate human neural networks with artificial ones quickly fall apart under scrutiny. Brandt carves out one domain where he sees human creativity clearly soar above its machine-made counterparts: what he calls “amplifying the anomaly.” AI models operate in the realm of statistical sampling. They do not work by emphasizing the exceptional but, rather, by reducing errors and finding probable patterns. Humans, on the other hand, are intrigued by quirks. “Rather than being treated as oddball events or ‘one-offs,’” Brandt writes, the quirk “permeates the creative product.” He cites Beethoven’s decision to add a jarring offkey note in the last movement of his Symphony no. 8. “Beethoven could have left it at that,” Brandt says. “But rather than treating it as a one-off, Beethoven continues to reference this incongruous event in various ways. In doing so, the composer takes a momentary aberration and magnifies its impact.” One could look to similar anomalies in the backward loop sampling of late Beatles recordings, pitched-up vocals from Frank Ocean, or the incorporation of “found sounds,” like recordings of a crosswalk signal or a door closing, favored by artists like Charlie Puth and by Billie Eilish’s producer Finneas O’Connell. If a creative output is indeed defined as one that’s both novel and useful, Brandt’s interpretation suggests that the machines may have us matched on the second criterion while humans reign supreme on the first. To explore whether that is true, I spent a few days playing around with Udio’s model. It takes a minute or two to generate a 30-second sample, but if you have paid versions of the model you can generate whole songs. I decided to pick 12 genres, generate a song sample for each, and then find similar songs made by people. I built a quiz to see if people in our newsroom could spot which songs were made by AI. The average score was 46%. And for a few genres, especially instrumental ones, listeners were wrong more often than not. When I watched people do the test in front of me, I noticed that the qualities they confidently flagged as a sign of composition by AI—a fake-sounding instrument, a weird lyric—rarely proved them right. Predictably, people did worse in genres they were less familiar with; some did okay on country or soul, but many stood no chance against jazz, classical piano, or pop. Beaty, the creativity researcher, scored 66%, while Brandt, the composer, finished at 50% (though he answered correctly on the orchestral and piano sonata tests). Remember that the model doesn’t deserve all the credit here; these outputs could not have been created without the work of human artists whose work was in the training data. But with just a few prompts, the model generated songs that few people would pick out as machinemade. A few could easily have been played at a party without raising objections, and I found two I genuinely loved, even as a lifelong musician and generally picky music person. But sounding real is not the same thing as sounding original. The songs did not feel driven by oddities or anomalies—certainly not on the level of Beethoven’s “jump scare.” Nor did they seem to bend genres or cover great leaps between themes. In my test, people sometimes struggled to decide whether a song was AI-generated or simply bad. How much will this matter in the end? The courts will play a role in deciding whether AI music models serve up replications or new creations—and how artists are compensated in the process—but we, as listeners, will decide their cultural value. To appreciate a song, do we need to picture a human artist behind it—someone with experience, ambitions, opinions? Is a great song no longer great if we find out it’s the product of AI? Sanchez says people may wonder who is behind the music. But “at the end of the day, however much AI component, however much human component, it’s going to be art,” he says. “And people are going to react to it on the quality of its aesthetic merits.” In my experiment, though, I saw that the question really mattered to people—and some vehemently resisted the idea of enjoying music made by a computer model. When one of my test subjects instinctively started bobbing her head to an electro-pop song on the quiz, her face expressed doubt. It was almost as if she was trying her best to picture a human rather than a machine as the song’s composer. “Man,” she said, “I really hope this isn’t AI.” It was. Is the result creation or simply replication of the training data? We could ask the same question about human creativity.

But preparing for that day without testing nukes in space means getting creative. A T O M S F O R ASTEROIDS By Robin George Andrews MJ25-feature_asteroids.indd 42 Illustrations by MCKIBILLO 4/1/25 3:5 PM MJ25-feature_asteroids.indd 43 4/1/25 3:5 PM 44 One day, in the near or far future, an asteroid about the length of a football stadium will find itself on a collision course with Earth. If we are lucky, it will land in the middle of the vast ocean, creating a good-size but innocuous tsunami, or in an uninhabited patch of desert. But if it has a city in its crosshairs, one of the worst natural disasters in modern times will unfold. As the asteroid steams through the atmosphere, it will begin to fragment— but the bulk of it will likely make it to the ground in just a few seconds, instantly turning anything solid into a fluid and excavating a huge impact crater in a heartbeat. A colossal blast wave, akin to one unleashed by a large nuclear weapon, will explode from the impact site in every direction. Homes dozens of miles away will fold like cardboard. Millions of people could die. Fortunately for all 8 billion of us, planetary defense—the science of preventing asteroid impacts—is a highly active field of research. Astronomers are watching the skies, constantly on the hunt for new near-Earth objects that might pose a threat. And others are actively working on developing ways to prevent a collision should we find an asteroid that seems likely to hit us. We already know that at least one method works: ramming the rock with an uncrewed spacecraft to push it away from Earth. In September 2022, NASA’s Double Asteroid Redirection Test, or DART, showed it could be done when a semiautonomous spacecraft the size of a small car, with solar panel wings, was smashed into an (innocuous) asteroid named Dimorphos at 14,000 miles per hour, successfully changing its orbit around a larger asteroid named Didymos. But there are circumstances in which giving an asteroid a physical shove might not be enough to protect the planet. If that’s the case, MJ25-feature_asteroids.indd 44 we could need another method, one that is notoriously difficult to test in real life: a nuclear explosion. Scientists have used computer simulations to explore this potential method of planetary defense. But in an ideal world, researchers would ground their models with cold, hard, practical data. Therein lies a challenge. Sending a nuclear weapon into space would violate international laws and risk inflaming political tensions. What’s more, it could do damage to Earth: A rocket malfunction could send radioactive debris into the atmosphere. Over the last few years, however, scientists have started to devise some creative ways around this experimental limitation. The effort began in 2023, with a team of scientists led by Nathan Moore, a physicist and chemical engineer at the Sandia National Laboratories in Albuquerque, New Mexico. Sandia is a semi-secretive site that serves as the engineering arm of America’s nuclear weapons program. And within that complex lies the Z Pulsed Power Facility, or Z machine, a cylindrical metallic labyrinth of warning signs and wiring. It’s capable of summoning enough energy to melt diamond. The researchers reckoned they could use the Z machine to re-create the x-ray blast of a nuclear weapon— the radiation that would be used to knock back an asteroid—on a very small and safe scale. It took a while to sort out the details. But by July 2023, Moore and his team were ready. They waited anxiously inside a control room, monitoring the thrumming contraption from afar. Inside the machine’s heart were two small pieces of rock, stand-ins for asteroids, and at the press of a button, a maelstrom of x-rays would thunder toward them. If they were knocked back by those x-rays, it would prove something that, until now, was purely theoretical: You can deflect an asteroid from Earth using a nuke. This experiment “had never been done before,” says Moore. But if it About 25,000 asteroids more than 460 feet long—a size range that starts with midsize “city killers” and goes up in impact from there—are thought to exist close to Earth. Just under half of them have been found. succeeded, its data would contribute to the safety of everyone on the planet. Would it work? Monoliths and rubble piles Asteroid impacts are a natural disaster like any other. You shouldn’t lose sleep over the prospect, but if we get unlucky, an errant space rock may rudely ring Earth’s doorbell. “The probability of an asteroid striking Earth during my lifetime is very small. But what if one did? What would we do about it?” says Moore. “I think that’s worth being curious about.” 4/1/25 3:5 PM 45 Forget about the gigantic asteroids you know from Hollywood blockbusters. Space rocks over twothirds of a mile (about one kilometer) in diameter—those capable of imperiling civilization—are certainly out there, and some hew close to Earth’s own orbit. But because these asteroids are so elephantine, astronomers have found almost all of them already, and none pose an impact threat. Rather, it’s asteroids a size range down—those upwards of 460 feet (140 meters) long—that are of paramount concern. About 25,000 of those are thought to exist close to our planet, and just under half have been found. The day-to-day odds of an impact are extremely low, but even one of the smaller ones in that size range could do significant damage if it found Earth and hit a populated area—a capacity that has led astronomers to dub such midsize asteroids “city killers.” If we find a city killer that looks likely to hit Earth, we’ll need a way to stop it. That could be technology to break or “disrupt” the asteroid into fragments that will either miss the planet entirely or harmlessly ignite in the atmosphere. Or it could be something that can deflect the asteroid, pushing it onto a path that will no longer intersect with our blue marble. Because disruption could accidentally turn a big asteroid into multiple smaller, but still deadly, shards bound for Earth, it’s often considered to be a strategy of last resort. Deflection is seen as safer and more elegant. One way to achieve it is to deploy a spacecraft known as a kinetic impactor—a battering ram that collides with an asteroid and transfers its momentum to the rocky interloper, nudging it away from Earth. NASA’s DART mission demonstrated that this can work, but there are some important MJ25-feature_asteroids.indd 45 4/1/25 3:5 PM 46 caveats: You need to deflect the asteroid years in advance to make sure it completely misses Earth, and asteroids that we spot too late—or that are too big—can’t be swatted away by just one DART-like mission. Instead, you’d need several kinetic impactors—maybe many of them— to hit one side of the asteroid perfectly each time in order to push it far enough to save our planet. That’s a tall order for orbital mechanics, and not something space agencies may be willing to gamble on. In that case, the best option might instead be to detonate a nuclear weapon next to the asteroid. This would irradiate one hemisphere of the asteroid in x-rays, which in a few millionths of a second would violently shatter and vaporize the rocky surface. The stream of debris spewing out of that surface and into space would act like a rocket, pushing the asteroid in the opposite direction. “There are scenarios where kinetic impact is insufficient, and we’d have to use a nuclear explosive device,” says Moore. This idea isn’t new. Several decades ago, Peter Schultz, a planetary geologist and impacts expert at Brown University, was giving a planetary defense talk at the Lawrence Livermore National Laboratory in California, another American lab focused on nuclear deterrence and nuclear physics research. Afterwards, he recalls, none other than Edward Teller, the father of the hydrogen bomb and a key member of the Manhattan Project, invited him into his office for a chat. “He wanted to do one of these near-Earth-asteroid flybys and wanted to test the nukes,” Schultz says. What, he wondered, would happen if you blasted an asteroid with a nuclear weapon’s x-rays? Could you forestall a spaceborne disaster using weapons of mass destruction? MJ25-feature_asteroids.indd 46 But Teller’s dream wasn’t fulfilled—and it’s unlikely to become a reality anytime soon. The United Nations’ 1967 Outer Space Treaty states that no nation can deploy or use nuclear weapons off-world (even if it’s not clear how long certain spacefaring nations will continue to adhere to that rule). Even raising the possibility of using nukes to defend the planet can be tricky. “There’re still many folks that don’t want to talk about it at all … even if that were the only option to prevent an impact,” says Megan Bruck Syal, a physicist and planetary defense researcher at Lawrence Livermore. Nuclear weapons have long been a sensitive subject, and with relations between several nuclear nations currently at a new nadir, anxiety over the subject is understandable. But in the US, there are groups of scientists who “recognize that we have a special responsibility as a spacefaring nation and as a nuclearcapable nation to look at this,” Syal says. “It isn’t our preference to use a nuclear explosive, of course. But we are still looking at it, in case it’s needed.” But how? Mostly, researchers have turned to the virtual world, using supercomputers at various US laboratories to simulate the asteroid-agitating physics of a nuclear blast. To put it mildly, “this is very hard,” says Mary Burkey, a physicist and planetary defense researcher at Lawrence Livermore. You cannot simply flick a switch on a computer and get immediate answers. “When a nuke goes off in space, there’s just x-ray light that’s coming out of it. It’s shining on the surface of your asteroid, and you’re tracking those little photons penetrating maybe a tiny little bit into the surface, and then somehow you have to take that micrometer worth of resolution and then The Z Pulsed Power Facility, or Z machine, at Sandia National Laboratories in Albuquerque, New Mexico, concentrates electricity into short bursts of intense energy that can be used to create x-rays and gamma rays and compress matter to high densities. 4/1/25 3:5 PM RANDY MONTOYA/SANDIA NATIONAL LABORATORY 47 propagate it out onto something that might be on the order of hundreds of meters wide, watching that shock wave propagate and then watching fragments spin off into space. That’s four different problems.” Mimicking the physics of x-ray rock annihilation with as much verisimilitude as possible is difficult work. But recent research using these high-fidelity simulations does suggest that nukes are an effective planetary defense tool for both disruption and deflection. The thing is, though, no two asteroids are alike; each is mechanically and geologically unique, meaning huge uncertainties remain. A more monolithic asteroid might respond in a straightforward way to a nuclear deflection campaign, whereas a rubble pile asteroid—a weakly bound fleet of boulders barely held together by their own gravity—might respond in a chaotic, uncontrollable way. Can you be sure the explosion wouldn’t accidentally shatter the asteroid, turning a cannonball into a hail of bullets still headed for Earth? Simulations can go a long way toward answering these questions, but they remain virtual re-creations of reality, with built-in assumptions. “Our models are only as good as the physics that we understand and that we put into them,” says Angela Stickle, a hypervelocity impact physicist at the Johns Hopkins University Applied Physics Laboratory in Maryland. To make sure the simulations are reproducing the correct physics and delivering realistic data, physical experiments are needed to ground them. Researchers studying kinetic impactors can get that sort of realworld data. Along with DART, they can use specialized cannons— like the Vertical Gun Range at NASA’s Ames Research Center in California—to fire all sorts of MJ25-feature_asteroids.indd 47 projectiles at meteorites. In doing so, they can find out how tough or fragile asteroid shards can be, effectively reproducing a kinetic impact mission on a small scale. Battle-testing nuke-based asteroid defense simulations is another matter. Re-creating the physics of these confrontations on a small scale was long considered to be exceedingly difficult. Fortunately, those keen on fighting asteroids are as persistent as they are creative—and several teams, including Moore’s at Sandia, think they have come up with a solution. Every firing of the Z machine carries the energy of more than 1,000 lightning bolts, and each shot lasts a few millionths of a second. X-ray scissors The prime mission of Sandia, like that of Lawrence Livermore, is to help maintain the nation’s nuclear weapons arsenal. “It’s a national security laboratory,” says Moore. “Planetary defense affects the entire planet,” he adds—making it, by default, a national security issue as well. And that logic, in part, persuaded the powers that be in July 2022 to try a brand-new kind of experiment. Moore took charge of the project in January 2023—and with the shot scheduled for the summer, he had only a few months to come up with the specific plan for the experiment. There was “lots of scribbling on my whiteboard, running computer simulations, and getting data to our engineers to design the test fixture for the several months it would take to get all the parts machined and assembled,” he says. Although there were previous and ongoing experiments that showered asteroid-like targets with x-rays, Moore and his team were frustrated by one aspect of them. Unlike actual asteroids floating freely in space, the micro-asteroids on Earth were fixed in place. To truly test whether x-rays could deflect asteroids, targets would have to be suspended in a vacuum—and it wasn’t immediately clear how that could be achieved. Generating the nuke-like x-rays was the easy part, because Sandia had the Z machine, a hulking mass of diodes, pipes, and wires interwoven with an assortment of walkways that circumnavigate a vacuum chamber at its core. When it’s powered up, electrical currents are channeled into capacitors— and, when commanded, blast that energy at a target or substance to create radiation and intense magnetic pressures. Flanked by klaxons and flashing lights, it’s an intimidating sight. “It’s the size of a building—about three stories tall,” says Moore. Every firing of the Z machine carries the energy of more than 1,000 lightning bolts, and each shot lasts a few millionths of a second: “You can’t even blink that fast.” The Z machine is named for the axis along which its energetic particles cascade, but the Z could easily stand for “Zeus.” The original purpose of the Z machine, whose first form was built half a century ago, was nuclear fusion research. But over time, it’s been tinkered with, upgraded, and used for all kinds of science. “The Z machine has been used to compress matter to the same densities [you’d find at] the centers of planets. And we can do experiments like that to better understand how planets form,” Moore says, as an example. And the machine’s preternatural energies could easily be used to generate x-rays—in this case, by electrifying and collapsing a cloud of argon gas. “The idea of studying asteroid deflection is completely different for us,” says Moore. And the machine “fires just once a day,” he adds, “so all the experiments are planned more than a year in advance.” In other words, the researchers had to be 4/1/25 3:5 PM 48 near certain their one experiment would work, or they would be in for a long wait to try again—if they were permitted a second attempt. For some time, they could not figure out how to suspend their micro-asteroids. But eventually, they found a solution: Two incredibly thin bits of aluminum foil would hold their targets in place within the Z machine’s vacuum chamber. When the x-ray blast hit them and the targets, the pieces of foil would be instantly vaporized, briefly leaving the targets suspended in the chamber and allowing them to be pushed back as if they were in space. “It’s like you wave your magic wand and it’s gone,” Moore says of the foil. He dubbed this technique “x-ray scissors.” In July 2023, after considerable planning, the team was ready. Within the Z machine’s vacuum chamber were two fingernail-size targets—a bit of quartz and some fused silica, both frequently found on real asteroids. Nearby, a pocket of argon gas swirled away. Satisfied that the gigantic gizmo was ready, everyone left and went to stand in the control room. For a moment, it was deathly quiet. Stand by. Fire. It was over before their ears could even register a metallic bang. A tempest of electricity shocked the argon gas cloud, causing it to implode; as it did, it transformed into a plasma and x-rays screamed out of it, racing toward the two targets in the chamber. The foil vanished, the surfaces of both targets erupted outward as supersonic sprays of debris, and the targets flew backward, away from the x-rays, at 160 miles per hour. Moore wasn’t there. “I was in Spain when the experiment was run, because I was celebrating my anniversary with my wife, and there was no way I was going to MJ25-feature_asteroids.indd 48 miss that,” he says. But just after the Z machine was fired, one of his colleagues sent him a very concise text: IT WORKED. “We knew right away it was a huge success,” says Moore. The implications were immediately clear. The experimental setup was complex, but they were trying to achieve something extremely fundamental: a real-world demonstration that a nuclear blast could make an object in space move. Patrick King, a physicist at the Johns Hopkins University Applied Physics Laboratory, was impressed. Previously, pushing back objects using x-ray vaporization had been extremely difficult to demonstrate in the lab. “They were able to get a direct measurement of that momentum transfer,” he says, calling the x-ray scissors an “elegant” technique. Sandia’s work took many in the community by surprise. “The Z machine experiment was a bit of a newcomer for the planetary defense field,” says Burkey. But she notes that we can’t overinterpret the results. It isn’t clear, from the deflection of the very small and rudimentary asteroid-like targets, how much a genuine nuclear explosion would deflect an actual asteroid. As ever, more work is needed. King leads a team that is also working on this question. His NASA-funded project involves the Omega Laser Facility, a complex based at the University of Rochester in upstate New York. Omega can generate x-rays by firing powerful lasers at a target within a specialized chamber. Upon being irradiated, the target generates an x-ray flash, similar to the one produced during a nuclear explosion in space, which can then be used to bombard various objects—in this case, some Earth rocks acting as asteroid mimics, and (crucially) some bona fide meteoritic material too. King’s Omega experiments have tried to answer a basic question: “How much material actually gets removed from the surface?” says King. The amount of material that flies off the pseudo-asteroids, and the vigor with which it’s removed, will differ from target to target. The hope is that these results—which the team is still considering— will hint at how different types of asteroids will react to being nuked. Although experiments with Omega cannot produce the kickback seen in “We’re genuinely looking at this from the standpoint of ‘This is a technology that could save lives.’” the Z machine, King’s team has used a more realistic and diverse series of targets and blasted them with x-rays hundreds of times. That, in turn, should clue us in to how effectively, or not, actual asteroids would be deflected by a nuclear explosion. “I wouldn’t say one [experiment] has definitive advantages over the other,” says King. “Like many things in science, each approach can yield insight along different ‘axes,’ if you will, and no experimental setup gives you the whole picture.” Experiments like Moore’s and King’s may sound technologically 4/1/25 3:5 PM 49 baroque—a bit like lightning-fast Rube Goldberg machines overseen by wizards. But they are likely the first in a long line of increasingly sophisticated tests. “We’ve just scratched the surface of what we can do,” Moore says. As with King’s experiments, Moore hopes to place a variety of materials in the Z machine, including targets that can stand in for the wetter, more fragile carbon-rich asteroids that astronomers commonly see in near-Earth space. “If we could get our hands on real asteroid material, we’d do it,” he says. And it’s expected that all this experimental data will be fed back into those nuke-versus-asteroid computer simulations, helping to verify the virtual results. Although these experiments are perfectly safe, planetary defenders remain fully cognizant of the taboo around merely discussing the use of nukes for any reason—even if that reason is potentially saving the world. “We’re genuinely looking at this from the standpoint of ‘This is a technology that could save lives,’” King says. Inevitably, Earth will be imperiled by a dangerous asteroid. And the hope is that when that day arrives, it can be dealt with using something other than a nuke. But comfort should be taken from the fact that scientists are researching this scenario, just in case it’s our only protection against the firmament. “We are your taxpayer dollars at work,” says Burkey. There’s still some way to go before they can be near certain that this asteroid-stopping technique will succeed. Their progress, though, belongs to everyone. “Ultimately,” says Moore, “we all win if we solve this problem.” Robin George Andrews is an award-winning science journalist based in London and the author, most recently, of How to Kill an Asteroid: The Real Science of Planetary Defense. MJ25-feature_asteroids.indd 49 4/1/25 3:5 PM 50 Artificial intelligence is painting pictures, writing novels, making videos, and composing symphonies. Can it push the limits of what we build? By Allison Arieff Karl Daubmann College of Architecture and Design at Lawrence Technological University “The way I have been working with generative AI has been to mix multiple images together from vast libraries I have from architecture, construction, history, fashion, biology, etc.,” says Daubmann. “Very often the new synthetic image that comes from a tool like Midjourney or Stable Diffusion feels new, infused by each of the multiple tools but rarely completely derived from them.” Daubmann’s Instagram account “Robot Historian,” a daily account of a unique postindustrial, postrobotic landscape, has become a document for tracking the evolution of generative AI. MJ25-feature_architecture.indd 50 Architecture often assumes a binary between built projects and theoretical ones. What physics allows in actual buildings, after all, is vastly different from what architects can imagine and design (often referred to as “paper architecture”). That imagination has long been supported and enabled by design technology, but the latest advancements in artificial intelligence have prompted a surge in the theoretical. “Transductions: Artificial Intelligence in Architectural Experimentation,” a recent exhibition at the Pratt Institute in Brooklyn, brought together works from over 30 practitioners exploring the experimental, generative, and collaborative potential of artificial intelligence to open up new areas of architectural inquiry—something they’ve been working on for a decade or more, since long before AI became mainstream. Architects and exhibition co-curators Jason VigneriBeane, Olivia Vien, Stephen Slaughter, and Hart Marlow explain that the works in “Transductions” emerged out of feedback loops among architectural discourses, techniques, formats, and media that range from imagery, text, and animation to mixed-reality media and fabrication. The aim isn’t to present projects that are going to break ground anytime soon; architects already know how to build things with the tools they have. Instead, the show attempts to capture this very early stage in architecture’s exploratory engagement with AI. Technology has long enabled architecture to push the limits of form and function. As early as 1963, Sketchpad, one of the first architectural software programs, allowed architects and designers to move and change objects on screen. Rapidly, traditional hand drawing gave way to an ever-expanding suite of programs—Revit, SketchUp, and BIM, among many others— that helped create floor plans and sections, track buildings’ energy usage, enhance sustainable construction, and aid in following building codes, to name just a few uses. The architects exhibiting in “Transductions” view newly evolving forms of AI “like a new tool rather than a professionending development,” says Vigneri-Beane, despite what some of his peers fear about the technology. He adds, “I do appreciate that it’s a somewhat unnerving thing for people, [but] I feel a familiarity with the rhetoric.” After all, he says, AI doesn’t just do the job. “To get something interesting and worth saving in AI, an enormous amount of time is required,” he says. “My architectural vocabulary has gotten much more precise and my visual sense has gotten an incredible workout, exercising all these muscles which have atrophied a little bit.” Vien agrees: “I think these are extremely powerful tools for an architect and designer. Do I think it’s the entire future of architecture? No, but I think it’s a tool and a medium that can expand the long history of mediums and media that architects can use not just to represent their work but as a generator of ideas.” Allison Arieff is editorial director of MIT Technology Review.

The story of the Arm atro n By Jon Keegan Photographs by Jim Golden As a child of an electronic engineer, I spent a lot of time in our local Radio Shack as a kid. While my dad was locating capacitors and resistors, I was in the toy section. It was there, in 1984, that I discovered the best toy of my childhood: the Armatron robotic arm. Described as a “robot-like arm to aid young masterminds in scientific and laboratory experiments,” it was the rare toy that lived up to the hype printed on the front of the box. This was a legit robotic arm. You could rotate the arm to spin around its base, tilt it up and down, bend it at the “elbow” joint, rotate the “wrist,” and open and close the bright-orange articulated hand in elegant chords of movement, all using only the twistable twin joysticks. Anyone who played with this toy will also remember the sound it made. Once you slid the power button to the On position, you heard a MJ25-back_armatron.indd 58 3/2 /25 :5 M 59 MJ25-back_armatron.indd 59 3/2 /25 :5 M constant whirring sound of plastic gears turning and twisting. And if you tried to push it past its boundaries, it twitched and protested with a jarring “CLICK … CLICK … CLICK.” It wasn’t just kids who found the Armatron so special. It was featured on the cover of the November/ December 1982 issue of Robotics Age magazine, which noted that the $31.95 toy (about $96 today) had “capabilities usually found only in much more expensive experimental arms.” A few years ago I found my Armatron, and when I opened the case to get it working again, I was startled to find that other than the compartment for the pair of D-cell batteries, a switch, and a tiny threevolt DC motor, this thing was totally devoid of any electronic components. It was purely mechanical. Later, I found the patent drawings for the Armatron online and saw how incredibly complex the schematics of the gearbox were. This design was the work of a genius—or a madman. The man behind the arm A drawing from the patent application for the Armatron robotic arm. MJ25-back_armatron.indd 60 I needed to know the story of this toy. I reached out to the manufacturer, Tomy (now known as Takara Tomy), which has been in business in Japan for over 100 years. It put me in touch with Hiroyuki Watanabe, a 69-year-old engineer and toy designer living in Tokyo. He’s retired now, but he worked at Tomy for 49 years, building many classic handheld electronic toys of the ’80s, including Blip, Digital Diamond, Digital Derby, and Missile Strike. Watanabe’s name can be found on 44 patents, and he was involved in bringing between 50 and 60 products to market. Watanabe answered emailed questions via video, and his responses were translated from Japanese. “I didn’t have a period where I studied engineering professionally. Instead, I enrolled in what Japan would call a technical high school that trains technical engineers, and I actually [entered] the electrical department there,” he told me. Afterward, he worked at Komatsu Manufacturing—because, he said, he liked bulldozers. But in 1974, he saw that Tomy was hiring, and he wanted to make toys. “I was told that it was the No. 1 toy company in Japan, so I decided [it was worth a look],” he said. “I took a night train from Tohoku to Tokyo to take a job exam, and that’s how I ended up joining the company.” The inspiration for the Armatron came from a newspaper clipping that Watanabe’s boss brought to him one day. “It showed an image of a [mechanical arm] holding an egg with three fingers. I think we started out thinking, ‘This is where things are heading these days, so let’s make this,’” he recalled. As the lead of a small team, Watanabe briefly turned his attention to another project, and by the time he returned to the robotic arm, the team had a prototype. But it was quite different from the Armatron’s final form. “The hand stuck out from the main body to the side and could only move about 90 degrees. The control panel also had six movement positions, and they were switched using six switches. I personally didn’t like that,” said Watanabe. So he went back to work. Watanabe’s breakthrough was inspired by the radio-controlled helicopters he operated as a hobby. Holding up a radio remote controller with dual joystick controls, he told me, “This stick operation allows you to perform four movements with two arms, but I thought that if you twist this part, you can use six movements.” “I had always wanted to create a system that could rotate 360 degrees, so I thought about how to make that system work,” he added.

A designer created the case, colors, and logo, adding touches to mimic features seen on industrial robots of the time, such as the rubber tubes (which are just for looks). When the Armatron first came out, in 1981, robotics engineers started contacting Watanabe. “I wasn’t so much hearing from people at toy stores, but rather from researchers at university laboratories, factories, and companies that were making industrial robots,” he said. “They were quite encouraging, and we often talked together.” The long reach of the robot at Radio Shack The bold look and function of Armatron made quite an impression on many young kids who would one day have a career in robotics. One of them was Adam Burrell, a mechanical design engineer who has been building robots for 15 years at Boston Dynamics, including Petman, the YouTube-famous Atlas, and the dog-size quadruped called Spot. Burrell grew up a few blocks away from a Radio Shack in New York City. “If I was going to the subway station, we would walk right by Radio Shack. I would stop in and play with it and set the timer, do the challenges,” he says. “I know it was a toy, but that was a real robot.” The Armatron was the hook that lured him into Radio Shack and then sparked his lifelong interest in engineering: “I would roll pennies and use them to buy soldering irons and solder at Radio Shack.” Burrell had a fateful reunion with the toy while in grad school for engineering. “One of my office mates had an Armatron at his desk,” he recalls, “and it was broken. We took it apart together, and that was the first time I had seen the guts of it. MJ25-back_armatron.indd 62 Clockwise from top left: The Armatron’s inventor, Hiroyuki Watanabe, in Tokyo, 2025.

And it was really fascinating that it had done so much— the one little motor. And that sort of got me back thinking about industrial robot arms again.” Eric Paulos, a professor of electrical engineering and computer science at the University of California, Berkeley, recalls nagging his parents about what an educational gift Armatron would make. Ultimately, he succeeded in his lobbying. “It was just endless exploration of picking stuff up and moving it around and even just watching it move. It was mesmerizing to me. I felt like I really owned my own little robot,” he recalls. “I cherish this thing. I still have it to this day, and it’s still working.” Today, Paulos builds robots and teaches his students how to build their own. He challenges them to solve problems within constraints, such as building with cardboard or “There’s research to this day using AI to try to figure out optimal ways to grab objects that [a robot] sees in a bin or out in the world.” MJ25-back_armatron.indd 63 Play-Doh; he believes the restrictions facing Watanabe and his team ultimately forced them to be more creative in their engineering. It’s not very hard to draw connections between the Armatron—an impossibly analog robot—and highly advanced machines that are today learning to move in incredible new ways, powered by AI advancements like computer vision and reinforcement learning. Paulos sees parallels between the problems he tackled as a kid with his Armatron and those that researchers are still trying to deal with today: “What happens when you pick things up and they’re too heavy, but you can sort of pick it up if you approach it from different angles? Or how do you grip things? There’s research to this day using AI to try to figure out optimal ways to grab objects that [a robot] sees in a bin or out in the world.” While AI may be taking over the world of robotics, the field still requires engineers—builders and tinkerers who can problem-solve in the physical world. The Armatron encouraged kids to explore these analog mechanics, a reminder that not all breakthroughs happen on a computer screen. And that hands-on curiosity hasn’t faded. Today, a new generation of fans are rediscovering the Armatron through online communities and DIY modifications. Dozens of Armatron videos are on YouTube, including one where the arm has been modified to run on steam power. “I’m very happy to see people who love mechanisms are amazed,” Watanabe told me. “I’m really happy that there are still people out there who love our products in this way.” Jon Keegan writes about technology and AI and publishes Beautiful Public Data, a curated collection of government data sets (beautifulpublicdata.com). 3/2 /25 :5 M Fighting drug overdoses with science Could NIST’s early warning system for new adulterants in street drugs help save lives? By Adam Bluestein MJ25-back_NIST.indd 64 In 2021, the Maryland Department of Health and the state police were confronting a crisis: Fatal drug overdoses in the state were at an all-time high, and authorities didn’t know why. There was a general sense that it had something to do with changes in the supply of illicit drugs—and specifically of the synthetic opioid fentanyl, which has caused overdose deaths in the US to roughly double over the past decade, to more than 100,000 per year. But Maryland officials were flying blind when it came to understanding these fluctuations in anything close to real time. The US Drug Enforcement Administration reported on the purity of drugs recovered in enforcement operations, but the DEA’s data offered limited detail and typically came back six to nine months after the seizures. By then, the actual drugs on the street had morphed many times over. Part of the investigative challenge was that fentanyl can be some 50 times more potent than heroin, and inhaling even a small amount can be deadly. This made conventional methods of analysis, which required handling the contents of drug packages directly, incredibly risky. Seeking answers, Maryland officials turned to scientists at the National Institute of Standards and Technology, the national metrology institute for the United States, which defines and maintains standards of measurement essential to a wide range of industrial sectors and health and security applications. There, a research chemist named Ed Sisco and his team had developed methods for detecting trace amounts of drugs, explosives, and other dangerous materials—techniques that could protect law enforcement officials and others who had to collect these samples. Essentially, Sisco’s lab had fine-tuned a technology called DART (for “direct analysis in real time”) mass spectrometry—which the US Transportation Security Administration uses to test for explosives by swiping your hand—to enable the detection of even tiny traces of chemicals collected from an investigation site. This meant that nobody had to open a bag or handle unidentified powders; a usable residue sample could be obtained by simply swiping the outside of the bag. Sisco realized that first responders or volunteers at needle exchange sites could use these same methods to safely collect drug Left: Ed Sisco’s lab at NIST developed a test that gives law enforcement and public health officials vital information about what substances are present in street drugs. B. HAYES/NIST (PORTRAIT); ANGELA WEISS/AFP VIA GETTY IMAGES 64 Right: A field researcher with the New York City Department of Health tests a heroin sample for xylazine. 3/2 /25 : 1 M 65 MJ25-back_NIST.indd 65 3/2 /25 : 1 M 66 residue from bags, drug paraphernalia, or used test strips—which also meant they would no longer need to wait for law enforcement to seize drugs for testing. They could then safely mail the samples to NIST’s lab in Maryland and get results back in as little as 24 hours, thanks to innovations in Sisco’s lab that shaved the time to generate a complete report from 10 to 30 minutes to just one or two. This was partly enabled by algorithms that allowed them to skip the time-consuming step of separating the compounds in a sample before running an analysis. The Rapid Drug Analysis and Research (RaDAR) program launched as a pilot in October 2021 and uncovered new, critical information almost immediately. Early analysis found xylazine—a veterinary sedative that’s been associated with gruesome wounds in users—in about 80% of opioid samples they collected. This was a significant finding, Sisco says: “Forensic labs care about things that are illegal, not things that are not illegal but do potentially cause harm. Xylazine is not a scheduled compound, but it leads to wounds that can lead to amputation, and it makes the other drugs more dangerous.” In addition to the compounds that are known to appear in high concentrations in street drugs—xylazine, fentanyl, and the veterinary sedative medetomidine—NIST’s technology can pick out trace amounts of dozens of adulterants that swirl through the street-drug supply and can make it more dangerous, including acetaminophen, rat poison, and local anesthetics like lidocaine. What’s more, the exact chemical formulation of fentanyl on the street is always changing, and differences in molecular structure can make the drugs deadlier. So Sisco’s team has developed new methods for spotting these “analogues”— compounds that resemble known chemical structures of fentanyl and related drugs. The RaDAR program has expanded to work with partners in public health, city and state law enforcement, forensic science, and customs agencies at about 65 sites in 14 states. Sisco’s lab processes 700 to 1,000 samples a month. About 85% come from public health organizations that focus on harm reduction (an approach to minimizing negative impacts of drug use for people who are not ready to quit). Results are shared at these collection points, which also collect survey data about the effects of the drugs. Jason Bienert, a wound-care nurse at Johns Hopkins who formerly volunteered with a nonprofit harm reduction organization in rural northern Maryland, started participating in the RaDAR program in spring 2024. “Xylazine hit like a storm here,” he says. “Everyone I took care of wanted to know what was in their drugs because they wanted to know if there was xylazine in it.” When the data started coming back, he says, “it almost became a race to see how many samples we could collect.” Bienert sent in about 14 samples weekly and created a chart on a dry-erase board, with drugs identified by the logos on their bags, sorted into columns according to the compounds found in them: heroin, fentanyl, xylazine, and everything else. MJ25-back_NIST.indd 66 “It was a super useful tool,” Bienert says. “Everyone accepted the validity of it.” As people came back to check on the results of testing, he was able to build rapport and offer additional support, including providing wound care for about 50 people a week. The breadth and depth of testing under the RaDAR program allow an eagle’s-eye view of the national street-drug landscape— and insights about drug trafficking. “We’re seeing distinct fingerprints from different states,” says Sisco. NIST’s analysis shows that fentanyl has taken over the opioid market—except for pockets in the Southwest, there is very little heroin on the streets anymore. But the fentanyl supply varies dramatically as you cross the US. “If you drill down in the states,” says Sisco, “you also see different fingerprints in different areas.” Maryland, for example, has two distinct fentanyl supplies—one with xylazine and one without. In summer 2024, RaDAR analysis detected something really unusual: the sudden appearance of an industrial-grade chemical called BTMPS, which is used to preserve plastic, in drug samples nationwide. In the human body, BTMPS acts as a calcium channel blocker, which lowers blood pressure, and mixed with xylazine or medetomidine, can make overdoses harder to treat. Exactly why and how BTMPS showed up in the drug supply isn’t clear, but it continues to be found in fentanyl samples at a sustained level since it was initially detected. “This was an example of a compound we would have never thought to look for,” says Sisco. To Sisco, Bienert, and others working on the public health front of the drug crisis, the ever-shifting chemical composition of the street-drug supply speaks to the futility of the “war on drugs.” They point out that a crackdown on heroin smuggling is what gave rise to fentanyl. And NIST’s data shows how in June 2024—the month after Pennsylvania governor Josh Shapiro signed a bill to make possession of xylazine illegal in his state— it was almost entirely replaced on the East Coast by the next veterinary drug, medetomidine. Over the past year, for reasons that are not fully understood, drug overdose deaths nationally have been falling for the first time in decades. One theory is that xylazine has longer-lasting effects than fentanyl, which means people using drugs are taking them less often. Or it could be that more and better information about the drugs themselves is helping people make safer decisions. “It’s difficult to say the program prevents overdoses and saves lives,” says Sisco. “But it increases the likelihood of people coming in to needle exchange centers and getting more linkages to wound care, other services, other education.” Working with public health partners “has humanized this entire area for me,” he says. “There’s a lot more gray than you think—it’s not black and white. And it’s a matter of life or death for some of these people.” Adam Bluestein writes about innovation in business, science, technology, and the creative economy. 3/2 /25 : 1 M Robert Blumofe Janel Thamkul Asha Sharma Vijay Badrinarayanan Executive Vice President & CTO, Akamai Deputy General Counsel, Anthropic Corporate Vice President, AI Platform, Microsoft VP of AI, Wayve Experience EmTech AI 2025 Live from Anywhere MIT Technology Review’s premier conference exploring AI’s real-world impact on business and innovation.

MJ25-back_comics.indd 68 4/2/25 1:15 PM 69 COURTESY OF THE PUBLISHER Generative AI is reshaping South Korea’s web comics industry “My mind is still sharp and my hands work just fine, so I have no interest in getting help from AI to draw or write stories,” says Lee Hyun-se, a legendary South Korean cartoonist best known for his seminal series A Daunting Team, a 1983 manhwa about the coming-of-age of heroic underdog baseball players. “Still, I’ve joined hands with AI to immortalize my characters Kkachi, Umji, and Ma Dong-tak.” By embracing generative AI, Lee is charting a new creative frontier in South Korea’s web comics industry. Since comics magazines faded at the turn of the century, web comics—serialized comics that read from top to bottom on digital platforms—have gone from niche subculture to global entertainment powerhouse, drawing in hundreds of millions of readers around the world. Lee has long been at its forefront, pushing the boundaries of his craft. Lee drew inspiration for his renegade baseball avengers from the Sammi Superstars, one of South Korea’s first professional baseball teams, whose journey of perseverance captivated a country stifled by military dictatorship. The series gained a cult following among readers seeking a creative escape from political repression, mesmerized by his bold brushstrokes and cinematic compositions that defied the conventions of cartoons. Kkachi, the rebellious protagonist in A Daunting Team, is an alter ego of Lee himself. A scrappy outcast with untamed, spiky hair, he is a fan favorite who challenges the world with unrelenting passion and a brave conscience. He has reappeared throughout Lee’s signature works, painted with a new layer of pathos each time—a supernatural warrior who saves Earth from an alien attack in Armageddon and a rogue police officer battling a powerful criminal syndicate in Karon’s Dawn. Over decades, Kkachi has become a cultural icon in South Korea. But Lee worries about Kkachi’s future. “In South Korea, when an author dies, his characters also get buried in his grave,” he says, drawing contrasts with enduring The technology is unlocking new creative possibilities while fueling anxieties over artistic agency and authorship. By Michelle Kim MJ25-back_comics.indd 69 4/2/25 1:15 PM 70 MJ25-back_comics.indd 70 to human expressions. The grand vision of his experimental AI project is to create a “Lee Hyun-se simulation agent”—an advanced generation of his AI model that replicates his creative mind. The model would be trained on digital archives of Lee’s essays, interviews, and texts from his comics—the subject of an exhibit at the National Library of Korea last year— to encode his philosophy, personality, and values. “It’s going to take a long time for AI to learn my myriad worldviews because I’ve published so much work,” he says. The digital clone of Lee would generate new comics with his artistic intuition, perceiving its environment and making creative choices as he would—perhaps even publishing a series far in the future starring Kkachi as a post-human protagonist. “Fifty years from now, what kinds of comics would Lee Hyun-se create if he saw the world then?” Lee asks. “The question fascinates me.” L ee’s quest for a lasting artistic legacy is part of a broader creative evolution driven by technology. In the decades since their emergence, web comics have transformed the art of storytelling, offering an infinite digital canvas that integrates music, animation, and interactive visuals with the effects of new tools like automated coloring programs. The addition of AI is spurring the next wave of innovation. But even as it unlocks new creative possibilities, it is fueling anxieties over artistic agency and authorship. Last year the South Korean startup Onoma AI, named after the Greek word for “name” (a signal of its ambition to redefine creative storytelling), launched an AI-powered web comic generator called TooToon. The software allows users to create synopses, characters, and storyboards with simple text prompts and convert rough sketches into polished illustrations that reflect their personal artistic style. TooToon claims to streamline the laborintensive creative process by cutting down the production time between concept development and line art from six months to just two weeks. Companies like Onoma AI champion the idea that AI can help anyone be an artist—even if you can’t draw or afford to hire an army of assistants to keep up with the industry’s insane production demands. In their vision, artists would emerge as directors of their own AI-powered solo studios, automating the grunt work of drawing and channeling their creative energy into storytelling and art direction. The productivity breakthrough, they say, would help artists brainstorm more experimental ideas, take on big-scale productions, and disrupt the studio monopolies that dominate the market. “AI would expand the web comic ecosystem,” says Song Min, the founder and CEO of Onoma AI. Song describes the industry in South Korea as a “pyramid”— powerhouse platforms like Naver Webtoon and Kakao Webtoon at the top, followed by big-shot studios, where artists collaborate to mass-produce web comics. “The rest of the artists, those outside the studio system, can’t create alone,” he explains. “AI would empower more artists to emerge as independent artists.” Last year, Onoma AI partnered with a group of young web comic artists to create Tarot: A Tale of Seven Pages, a mystery thriller unraveling the twisted fates of strangers cursed by a hand of tarot cards. Through these collaborations, Song uses the artists’ feedback to refine TooToon. Still, even as a champion of AI-generated art, he questions whether it’s “a good thing for AI to be perfect.” Just as engineers need to keep coding to hone their skills, he wonders if AI should leave room for artists to keep drawing to nurture their craft. COURTESY OF THE PUBLISHER American comic characters like Superman and Spider-Man. Lee craves artistic immortality. He wants his characters to stay alive not just in the memories of readers, but also on their web comic platforms. “Even after I die, I want my worldviews and characters to communicate and resonate with the people of a new era,” he says. “That’s the kind of immortality I want.” Lee believes that AI can help him realize his vision. In partnership with Jaedam Media, a web comics production company based in Seoul, he developed the “Lee Hyun-se AI model” by fine-tuning the open-source AI art generator Stable Diffusion, created by the UK-based startup Stability AI. Using a data set of 5,000 volumes of comics that he has published over 46 years, the resulting model generates comics in his signature style. This year, Lee is preparing to publish his first AI-assisted web comic, a remake of his 1994 manhwa Karon’s Dawn. Writers at Jaedam Media are adapting the story into a modernized crime drama starring Kkachi as a police officer in present-day Seoul and his love interest Umji as a daring prosecutor. Students at Sejong University, where Lee teaches comics, are creating the artwork using his AI model. The creative process unfolds in several stages. First, Lee’s AI model generates illustrations based on text prompts and reference images, like 3D anatomy models and hand-drawn sketches that provide cues for different movements and gestures. Lee’s students then curate and edit the illustrations, adjusting the characters’ poses, tailoring their facial expressions, and integrating them into cartoonish compositions that AI can’t engineer. After many rounds of refinement and regeneration, Lee steps in to orchestrate the final product, adding his distinct artistic edge. “Under my direction, a character might glare with sad eyes even when they’re angry or ferocious eyes when they’re happy,” he says. “It’s a subversive expression, a nuance that AI struggles to capture. Those delicate details I need to direct myself.” Ultimately, Lee wants to build an AI system that embodies his meticulous approach In AI companies’ vision, artists could automate the grunt work of drawing and channel their creative energy into storytelling and art direction. 4/2/25 1:15 PM 71 Oh Hye-seong is the protagonist of Karon’s Dawn, an AI-assisted web comic series by the South Korean cartoonist Lee Hyun-se, which will be released later this year. MJ25-back_comics.indd 71 4/2/25 1:15 PM “AI is an inevitable tour de force, but for now, the big hurdles lie in artists’ perception and copyright,” he says. Onoma AI built Illustrious, the large language model powering TooToon, by fine-tuning Stable Diffusion on the Danbooru2023 data set, a public image bank of anime-style illustrations. But Stable Diffusion, along with other popular image generators built on the model, has come under fire for indiscriminately scraping images from the internet, sparking a barrage of lawsuits over copyright infringement. In turn, web comic generators are facing intense backlash from artists who fear that the programs are being trained on their art without their consent. As companies silo their training data, artists and readers have launched a digital campaign to boycott AI-generated web comics. In May 2023, readers bombarded The Knight King Returns with the Gods on Naver Webtoon with blazingly low ratings after discovering that AI had been used to refine portions of the artwork. The following month, artists flooded the platform with anonymous posts protesting “AI web comics created from theft,” sharply criticizing Naver’s contract policy requiring artists who publish on the platform to consent to having their works used as AI training data. To settle the standoff, the Korea Copyright Commission issued a set of guidelines in December 2023, urging AI developers to obtain permission from copyright holders before using their works as training data; articulate the purpose, scope, and duration of use; and provide fair compensation. A year later, amid growing calls from AI companies for access to more data, the South Korean government proposed carving out an exemption to copyright laws that would allow AI models to be trained on copyrighted works under the doctrine of fair use. But no legislation or regulation has yet established a clear legal framework, leaving artists in limbo. Above, a strip from A Daunting Team, a 1983 baseball manhwa made by Lee Hyun-se.

Who knows?” property to AI, younger artists see it as a threat. They fear that AI will steal their artwork and, more important, their identity as artists. “Drawing is the most difficult and the most fun part of making comics,” says Park So-won, a young web comic artist based in Seoul. Park grew up dreaming of becoming a cartoonist, watching her mother, an animator, bring characters to life. After years of juggling gigs as an artist assistant at a web comics studio, interrupted by a brief creative hiatus, she made her breakthrough on the platform Lezhin Comics with Legs That Won’t Walk, a queer romance noir about a boxer who falls in love with a loan shark chasing after him over his alcoholic father’s debt. As an independent artist, Park is constantly at work. She publishes a new episode every 10 days, often pulling all-nighters to produce up to 80 cuts of drawing, even with the help of assistants handling background art and coloring. Occasionally she finds herself in a flow state, working 30 hours straight without a break. Still, Park can’t imagine outsourcing her drawings, which she sees as the heart of her comics, to AI. “The crux of a comic, however important the story, is the drawing. If the story were written in words, people wouldn’t have read it, would they? The story is just a thought—the execution is the drawing,” she says. “The grammar of comics is the drawing.” Handing over her drawing would mean surrendering her artistic agency. Park thinks algorithmic art lacks soul— like “objects that exist in a void”—and isn’t worried about whether AI can draw better than she does. Her drawings have evolved over the years, shaped by her shifting outlook on the world and breaking new creative ground over time—an artistic progression that she thinks an algorithm trained to emulate existing works could MJ25-back_comics.indd 73 never make. “I’ll keep charting new territory as an artist, while AI will stay the same,” she says. To Park, art is supreme indulgence: “I’ve come this far because I love to draw. If AI takes away my favorite thing to do in the world, what would I do?” But other comic artists, whose strengths lie in storytelling, welcome the innovation. Bae Jin-soo was an aspiring screenwriter before debuting as an artist on Naver Webtoon’s amateur comics page in 2010. To turn his screenplay into a comic, Bae taught himself to draw by photographing different compositions and tracing them on paper. “I can’t draw, so I’ll bet on my writing,” he thought. After his debut series Friday: Forbidden Tales took off, Bae rose to stardom with his three-part series Money Game, Pie Game, and Funny Game—brainy psychological thrillers packed with plot twists and witty, thought-provoking narratives about a group of contestants playing eccentric games to win a cash prize. They have even inspired a popular Netflix adaptation, The 8 Show. “I still have so many more stories I want to tell,” Bae says. A prolific writer, he keeps a running list of new ideas in a pocket notepad, the genre-bending plots spanning horror, politics, and black comedy. But with his mind racing ahead of his hand, breathing life into all his ideas would require commissioning a studio to execute the illustrations. For Bae, an AI-powered web comic generator could be a game changer. “If AI could handle my artwork, I would create an endless stream of new comics,” he says. Bae is also eager to explore AI as a “backup battery for story ideas,” like a writer’s assistant. Even so, to hold his ground as an artist, he plans to dig deeper into his imagination to generate original and experimental ideas that could be found nowhere else. “That’s the domain of [human] creators,” he says. Still, Bae wonders if his own creative edge would slowly erode through extensive collaboration with AI: “Would my own colors start to fade?” Meanwhile, comics students at Sejong University in Seoul are learning to integrate AI into their tool kits. The budding artists are being trained as “creative coders,” turning strips of comics into data sets by meticulously annotating their content, and as prompt engineers who can guide AI to produce characters that align with their aesthetic sensibilities. “Creativity takes time—to reflect and contemplate on your work,” says Han Chang-wan, a professor of comics and animation at Sejong University, who teaches a class on AI-generated web comics. Han says that’s what AI will buy for his students: the time to “create more diverse characters, more kaleidoscopic plots, and more eclectic genres” that challenge the formulaic comics mass-produced by studios. Ultimately, he hopes, they’ll “tap into an entirely new readership.” As artists navigate this uncharted future, generative AI is raising profound questions about what powers creativity. “AI could be a technical assistant to artists,” says Shin Il-sook, the president of the Korea Cartoonist Association and the renowned cartoonist behind the historical fantasy romance The Four Daughters of Armian, which follows a brave-hearted princess exiled from a matriarchal kingdom as she embarks on a journey of survival and self-discovery through war, love, and political power battles. Still, she wonders if AI can really be a creative companion. “Creativity is about making something never seen before, driven by a desire to share it with other people,” Shin says. “It’s deeply intertwined with the human experience and its afflictions. That’s why an artist who has walked through life’s suffering and honed their craft produces remarkable art,” she says. “Can you create without a soul? Who knows?” Michelle Kim is a freelance journalist and lawyer based in Seoul. 4/2/25 1:15 PM 74 The AI is present In 2021, 20 years after the death of her older sister, Vauhini Vara was still unable to tell the story of her loss. “I wondered,” she writes in Searches, her new collection of essays on AI technology, “if Sam Altman’s machine could do it for me.” So she tried ChatGPT. But as it expanded on Vara’s prompts in sentences ranging from the stilted to the unsettling to the sublime, the thing she’d enlisted as a tool stopped seeming so mechanical. “Once upon a time, she taught me to exist,” the AI model wrote of the young woman Vara had idolized. Vara, a journalist and novelist, called the resulting essay “Ghosts,” and in her opinion, the best lines didn’t come from her: “I found myself irresistibly attracted to GPT-3—to the way it offered, without judgment, to deliver words to a writer who has found MJ25-back_books.indd 74 herself at a loss for them … as I tried to write more honestly, the AI seemed to be doing the same.” The rapid proliferation of AI in our lives introduces new challenges around authorship, authenticity, and ethics in work and art. But it also offers a particularly human problem in narrative: How can we make sense of these machines, not just use them? And how do the words we choose and stories we tell about technology affect the role we allow it to take on (or even take over) in our creative lives? Both Vara’s book and The Uncanny Muse, a collection of essays on the history of art and automation by the music critic David Hajdu, explore how humans have historically and personally wrestled with the ways in which machines relate to our own bodies, brains, and creativity. At the Three books examine what we gain and lose when we let machines create.

NORTON & COMPANY, 2025 The Mind Electric: A Neurologist on the Strangeness and Wonder of Our Brains Pria Anand WASHINGTON SQUARE PRESS, 2025 3/2 /25 : 4 M MJ25-back_books.indd 75 3/2 /25 : 4 M 76 same time, The Mind Electric, a new book by a neurologist, Pria Anand, reminds us that our own inner workings may not be so easy to replicate. Searches is a strange artifact. Part memoir, part critical analysis, and part AI-assisted creative experimentation, Vara’s essays trace her time as a tech reporter and then novelist in the San Francisco Bay Area alongside the history of the industry she watched grow up. Tech was always close enough to touch: One college friend was an early Google employee, and when Vara started reporting on Facebook (now Meta), she and Mark Zuckerberg became “friends” on his platform. In 2007, she published a scoop that the company was planning to introduce ad targeting based on users’ personal information—the first shot fired in the long, gnarly data war to come. In her essay “Stealing Great Ideas,” she talks about turning down a job reporting on Apple to go to graduate school for fiction. There, she wrote a novel about a tech founder, which was later published as The Immortal King Rao. Vara points out that in some ways at the time, her art was “inextricable from the resources [she] used to create it”— products like Google Docs, a MacBook, an iPhone. But these pre-AI resources were tools, plain and simple. What came next was different. Interspersed with Vara’s essays are chapters of back-and-forths between the author and ChatGPT about the book itself, where the bot serves as editor at Vara’s prompting. ChatGPT obligingly summarizes and critiques her writing in a corporate-shaded tone that’s now familiar to any knowledge worker. “If there’s a place for disagreement,” it offers about the first few chapters on tech companies, “it might be in the balance of these narratives. Some might argue that the benefits—such as job creation, innovation in various sectors like AI and logistics, and contributions to the global economy—can outweigh the negatives.” Vara notices that ChatGPT writes “we” and “our” in these responses, pulling it into the human story, not the tech one: MJ25-back_books.indd 76 “Earlier you mentioned ‘our access to information’ and ‘our collective experiences and understandings.’” When she asks what the rhetorical purpose of that choice is, ChatGPT responds with a numbered list of benefits including “inclusivity and solidarity” and “neutrality and objectivity.” It adds that “using the first-person plural helps to frame the discussion in terms of shared human experiences and collective challenges.” Does the bot believe it’s human? Or at least, do the humans who made it want other humans to believe it does? “Can corporations use these [rhetorical] tools in their products too, to subtly make people identify with, and not in opposition to, them?” Vara asks. ChatGPT replies, “Absolutely.” curtain. The GPT models and others are trained through human labor, in sometimes exploitative conditions. And much of the training data was the creative work of human writers before her. “I’d conjured artificial language about grief through the extraction of real human beings’ language about grief,” she writes. The creative ghosts in the model were made of code, yes, but also, ultimately, made of people. Maybe Vara’s essay helped cover up that truth too. In the book’s final essay, Vara offers a mirror image of those AI call-and-response exchanges as an antidote. After sending out an anonymous survey to women of various ages, she presents the replies to each question, one after the other. “Describe something that doesn’t exist,” she prompts, The rapid proliferation of AI in our lives introduces new challenges around authorship, authenticity, and ethics in work and art. How can we make sense of these machines, not just use them? Vara has concerns about the words she’s used as well. In “Thank You for Your Important Work,” she worries about the impact of “Ghosts,” which went viral after it was first published. Had her writing helped corporations hide the reality of AI behind a velvet curtain? She’d meant to offer a nuanced “provocation,” exploring how uncanny generative AI can be. But instead, she’d produced something beautiful enough to resonate as an ad for its creative potential. Even Vara herself felt fooled. She particularly loved one passage the bot wrote, about Vara and her sister as kids holding hands on a long drive. But she couldn’t imagine either of them being so sentimental. What Vara had elicited from the machine, she realized, was “wish fulfillment,” not a haunting. The machine wasn’t the only thing crouching behind that too-good-to-be-true and the women respond: “God.” “God.” “God.” “Perfection.” “My job. (Lost it.)” Real people contradict each other, joke, yell, mourn, and reminisce. Instead of a single authoritative voice—an editor, or a company’s limited style guide—Vara gives us the full gasping crowd of human creativity. “What’s it like to be alive?” Vara asks the group. “It depends,” one woman answers. David Hajdu, now music editor at The Nation, and previously a music critic for The New Republic, goes back much further than the early years of Facebook to tell the history of how humans have made and used machines to express ourselves. Player pianos, microphones, synthesizers, and electrical instruments were all assistive technologies that faced skepticism before acceptance and, sometimes, elevation in music and popular culture. 3/2 /25 : 4 M Expand your knowledge beyond the classroom.

Electrical amplification, for instance, allowed singers to use a wider vocal range and still reach an audience. The synthesizer introduced a new lexicon of sound to rock music. “What’s so bad about being mechanical, anyway?” Hajdu asks in The Uncanny Muse. And “what’s so great about being human?” But Hajdu is also interested in how intertwined the history of man and machine can be, and how often we’ve used one as a metaphor for the other. Descartes saw the body as empty machinery for consciousness, he reminds us. Hobbes wrote that “life is but a motion of limbs.” Freud described the mind as a steam engine. Andy Warhol told an interviewer that “everybody should be a machine.” And when computers entered the scene, humans used them as metaphors for themselves too. “Where the machine model had once helped us understand the human body … a new category of machines led us to imagine the brain (how we think, what we know, even how we feel or how we think about what we feel) in terms of the computer,” Hajdu writes. But what is lost with these one-toone mappings? What happens when we imagine that the complexity of the brain— an organ we do not even come close to fully understanding—can be replicated in 1s and 0s? Maybe what happens is we get a world full of chatbots and agents, computer-generated artworks and AI DJs, that companies claim are singular creative voices rather than remixes of a million human inputs. And perhaps we also get projects like the painfully named Painting Fool—an AI that paints, developed by Simon Colton, a scholar at Queen Mary University of London. He told Hajdu that he wanted to “demonstrate the potential of a computer program to be taken seriously as a creative artist in its own right.” What Colton means is not just a machine that makes art but one that expresses its own worldview: “Art that communicates what it’s like to be a machine.” MJ25-back_books.indd 78 Hajdu seems to be curious and optimistic about this line of inquiry. “Machines of many kinds have been communicating things for ages, playing invaluable roles in our communication through art,” he says. “Growing in intelligence, machines may still have more to communicate, if we let them.” But the question that The Uncanny Muse raises at the end is: Why should we art-making humans be so quick to hand over the paint to the paintbrush? Why do we care how the paintbrush sees the world? Are we truly finished telling our own stories ourselves? Pria Anand might say no. In The Mind Electric, she writes: “Narrative is universally, spectacularly human; it is as unconscious as breathing, as essential along seams that few can find, and— yes—see and hear ghosts. In fact, Anand cites one study of 375 college students in which researchers found that nearly three-quarters “had heard a voice that no one else could hear.” These were not diagnosed schizophrenics or sufferers of brain tumors—just people listening to their own uncanny muses. Many heard their name, others heard God, and some could make out the voice of a loved one who’d passed on. Anand suggests that writers throughout history have harnessed organic exchanges with these internal apparitions to make art. “I see myself taking the breath of these voices in my sails,” Virginia Woolf wrote of her own experiences with ghostly sounds. “I am a porous vessel afloat on sensation.” What happens when we imagine that the complexity of the brain—an organ we do not even come close to fully understanding—can be replicated in 1s and 0s? as sleep, as comforting as familiarity. It has the capacity to bind us, but also to other, to lay bare, but also obscure.” The electricity in The Mind Electric belongs entirely to the human brain—no metaphor necessary. Instead, the book explores a number of neurological afflictions and the stories patients and doctors tell to better understand them. “The truth of our bodies and minds is as strange as fiction,” Anand writes—and the language she uses throughout the book is as evocative as that in any novel. In personal and deeply researched vignettes in the tradition of Oliver Sacks, Anand shows that any comparison between brains and machines will inevitably fall flat. She tells of patients who see clear images when they’re functionally blind, invent entire backstories when they’ve lost a memory, break The mind in The Mind Electric is vast, mysterious, and populated. The narratives people construct to traverse it are just as full of wonder. Humans are not going to stop using technology to help us create anytime soon—and there’s no reason we should. Machines make for wonderful tools, as they always have. But when we turn the tools themselves into artists and storytellers, brains and bodies, magicians and ghosts, we bypass truth for wish fulfillment. Maybe what’s worse, we rob ourselves of the opportunity to contribute our own voices to the lively and loud chorus of human experience. And we keep others from the human pleasure of hearing them too.

It is a foggy February weekend. Both are disappointed about how little sun there is on the California beach. They are two graduate students—Sophie in her sixth and final year, Martin in his fourth—who have traveled from different East Coast cities to present posters on their work. Martin’s shows health data collected from supercentenarians compared with the general Medicare population, capturing the diseases that are less and more common in the populations. Sophie is presenting on her recently accepted first-author paper in Aging Cell on two specific genes that, when activated, extend lifespan in C. elegans roundworms, the model organism of her research. 1 Sophie walks by Martin’s poster after she is done presenting her own. She is not immediately impressed by his work. It is not published, for one thing. But she sees how it is attention-grabbing and relevant, even necessary. He has a little crowd listening to him. He notices her—a frowning girl— standing in the back and begins to talk louder, hoping she hears. “Supercentenarians are much less likely to have seven diseases,” he says, pointing to his poster. “Alzheimer’s, heart failure, diabetes, depression, prostate cancer, hip fracture, and chronic kidney disease. Though they have higher instances of four diseases, which are arthritis, cataracts, osteoporosis, and glaucoma. These aren’t linked to mortality, but they do affect quality of life.” What stands out to Sophie is the confidence in Martin’s voice, despite the unsurprising nature of the findings. She admires that sound, its sturdiness. She makes note of his name and plans to seek him out. 2 They find one another in the hotel bar among other graduate students. The students are talking about the logistics of their futures: Who is going for a postdoc, who will opt for industry, do any have job offers already, where will their research have the most impact, is it worth spending years working toward something so uncertain? They stay up too late, dissecting journal articles they’ve read as if they were debating politics. They enjoy the freedom away from their labs and PIs. Martin says, again with that confidence, that he will become a professor. Sophie says she likely won’t go down that path. She has received an offer to start as a scientist at an aging research startup called Abyssinian Bio, after she defends. Martin says, “Wouldn’t your work make more sense in an academic setting, where you have more freedom and power over what you do?” She says, “But that could be years from now and I want to start my real life, so …” US FOOD & DRUG ADMINISTRATION 3 MJ25-back_fiction.indd 81 Martin is enamored with Sophie. She is not only brilliant; she is helpful. She strengthens his papers with precise edits and grounds his arguments with stronger evidence. Sophie is enamored with Martin. He is not only ambitious; he is 4-18 4/1/25 12:3 PM 82 Fiction supportive and adventurous. He encourages her to try new activities and tools, both in and out of work, like learning to ride a motorcycle or using CRISPR. Martin visits Sophie in San Francisco whenever he can, which amounts to a weekend or two every other month. After two years, their long-distance relationship is taking its toll. They want more weekends, more months, more everything together. They make plans for him to get a postdoc near her, but after multiple rejections from the labs where he most wants to work, his resentment toward academia grows. “They don’t see the value of my work,” he says. “Join Abyssinian,” Sophie offers. The company is growing. They want more researchers with data science backgrounds. He takes the job, drawn more by their future together than by the science. taking the task of living longer seriously enough. He does not want her to die. He does not want to die. Nobody at Abyssinian is taking the task of living longer seriously enough. Of all the aging bio startups he could have ended up at, how has he ended up at one with such modest— no, lazy—goals? He begins publicly dismissing basic research as “too slow” and “too limited,” which offends many of his and Sophie’s colleagues. Sophie defends him, says he is still doing good work, despite the evidence. She is busy, traveling often for conferences, and mistakenly misclassifies the changes in Martin’s attitude as temporary outliers. 19 20-35 For a long time, they are happy. They marry. They do their research. They travel. Sophie visits Martin’s extended family in France. Martin goes with Sophie to her cousin’s wedding in Taipei. They get a dog. The dog dies. They are both devastated but increasingly motivated to better understand the mechanisms of aging. Maybe their next dog will have the opportunity to live longer. They do not get a next dog. Sophie moves up at Abyssinian. Despite being in industry, her work is published in well-respected journals. She collaborates well with her colleagues. Eventually, she is promoted to executive director of research. Martin stalls at the rank of principal scientist, and though Sophie is technically his boss—or his boss’s boss—he genuinely doesn’t mind when others call him “Dr. Sophie Xie’s husband.” At dinner on his 35th birthday, a friend jokes that Martin is now middle-aged. Sophie laughs and agrees, though she is older than Martin. Martin joins in the laughter, but this small comment unlocks a sense of urgency inside him. What once felt hypothetical—his own death, the death of his wife— now appears very close. He can feel his wrinkles forming. First come the subtle shifts in how he talks about his research and Abyssinian’s work. He wants to “defeat” and “obliterate” aging, which he comes to describe as humankind’s “greatest adversary.” One day, during a meeting, Martin says to Jerry, a wellrespected scientist at Abyssinian and in the electron microscopy imaging community at large, that EM is an outdated, old, crusty technology. Martin says it is stupid to use it when there are more advanced, cutting-edge methods, like cryo-EM and super-resolution microscopy. Martin has always been outspoken, but this instance veers into rudeness. At home, Martin and Sophie argue. Initially, they argue about whether tools of the past can be useful to their work. Then the argument morphs. What is the true purpose of their research? Martin says it’s called anti-aging research for a reason: It’s to defy aging! Sophie says she’s never called her work anti-aging research; she calls it aging research or research into the biology of aging. And Abyssinian’s overarching mission is more simply to find druggable targets for chronic and age-related diseases. Occasionally, the company’s marketing arm will push out messaging about extending the human lifespan by 20 years, but that has nothing to do with scientists like them in R&D. Martin seethes. Only 20 years! What about hundreds? Thousands? 44 40 He begins taking supplements touted by tech influencers. He goes on a calorie-restricted diet. He gets weekly vitamin IV sessions. He looks into blood transfusions from young donors, but Sophie tells him to stop with all the fake science. She says he’s being ridiculous, that what he’s doing could be dangerous. Martin, for the first time, sees Sophie differently. Not without love, but love burdened by an opposing weight, what others might recognize as resentment. Sophie is dedicated to the demands of her growing department. Martin thinks she is not 43 MJ25-back_fiction.indd 82 45-49 They continue to argue and the arguments are round- about, typically ending with Sophie crying, absconding to her sister’s house, and the two of them not speaking for short periods of time. What hurts Sophie most is Martin’s persistent dismissal of death as merely an engineering problem to be solved. Sophie thinks of the ways the C. elegans she observes regulate their lifespans in response to environmental stress. The complex dance of genes and proteins that orchestrates their aging process. In the previous month’s experiment, a seemingly simple mutation produced unexpected effects across three generations of worms. Nature’s complexity still humbles her daily. There is still so much unknown. 50 Martin blames the past. He realizes he should have tried harder to become a professor. Let Sophie make the industry money—he could have had academic clout. Professor Warwick. It would have had a nice sound to it. To his dismay, everyone in 50 4/1/25 12:3 PM Fiction 83 his lab calls him Martin. Abyssinian has a first-name policy. Something about flat hierarchies making for better collaboration. Good ideas could come from anyone, even a lowly, unintelligent senior associate scientist in Martin’s lab who barely understands how to process a data set. A great idea could come from anyone at all—except him, apparently. Sophie has made that clear. They live in a tenuous peace for some time, perfecting the art of careful scheduling: separate coffee times, meetings avoided, short conversations that stick to the day-to-day facts of their lives. 51-59 Sophie thinks of the ways the C. elegans she observes regulate their lifespans in response to environmental stress. The complex dance of genes and proteins that orchestrates their aging process. Then Martin stands up to interrupt a presentation by the VP of research to announce that studying natural aging is pointless since they will soon eliminate it entirely. While Jerry may have shrugged off Martin’s aggressiveness, the VP does not. This leads to a blowout fight between Martin and many of his colleagues, in which Martin refuses to apologize and calls them all shortsighted idiots. Sophie watches with a mixture of fear and awe. Martin thinks: Can’t she, my wife, just side with me this once? 60 Back at home: Martin at the kitchen counter, methodically crushing his evening supplements into powder. “I’m trying to save humanity.” He taps the powder into his protein shake with the precision of a scientist measuring reagents. “And all you want to do is sit in the lab to watch worms die.” Sophie observes his familiar movements, now foreign in their desperation. The kitchen light catches the silver spreading at his temples and on his chin—the very evidence of aging he is trying so hard to erase. “That’s not true,” she says. Martin gulps down his shake. “What about us? What about children?” Martin coughs, then laughs, a sound that makes Sophie flinch. “Why would we have children now? You certainly don’t have the time. But if we solve aging, which I believe we can, we’d have all the time in the world.” “We used to talk about starting a family.” “Any children we have should be born into a world where we already know they never have to die.” “We could both make the time. I want to grow old together—” All Martin hears are promises that lead to nothing, nowhere. “You want us to deteriorate? To watch each other decay?” “I want a real life.” “So you’re choosing death. You’re choosing limitation. Mediocrity.” 61 Martin doesn’t hear from his wife for four days, despite texting her 16 times—12 too many, by his count. He finally breaks down enough to call her in the evening, after a couple of 64 MJ25-back_fiction.indd 83 4/1/25 12:3 PM 84 Fiction glasses of aged whisky (a gift from a former colleague, which Martin has rarely touched and kept hidden in the far back of a desk drawer). Voicemail. And after this morning’s text, still no glimmering ellipsis bubble to indicate Sophie’s typing. Forget her, he thinks, leaning back in his Steelcase chair, adjusted specifically for his long runner’s legs and shorterthan-average torso. At 39, Martin’s spreadsheets of vitals now show an upward trajectory; proof of his ability to reverse his biological age. Sophie does not appreciate this. He stares out his office window, down at the employees crawling around Abyssinian Bio’s main quad. How small, he thinks. How significantly unaware of the future’s true possibilities. Sophie is like them. 66 Forget her, he thinks again as he turns down a bay toward Robert, one of his struggling postdocs, who is sitting at his bench staring at his laptop. As Martin approaches, Robert minimizes several windows, leaving only his home screen behind. “Where are you at with the NAD+ data?” Martin asks. Robert shifts in his chair to face Martin. The skin of his neck grows red and splotchy. Martin stares at it in disgust. “Well?” he asks again. “Oh, I was told not to work on that anymore?” The boy has a tendency to speak in the lilt of questions. “By who?” Martin demands. “Uh, Sophie?” “I see. Well, I expect new data by end of day.” “Oh, but—” Martin narrows his eyes. The red splotches on Robert’s neck grow larger. “Um, okay,” the boy says, returning his focus to the computer. Martin decides a response is called for … 67 Immortality Promise I am immortal. This doesn’t make me special. In fact, most people on Earth are immortal. I am 6,000 years old. Now, 6,000 years of existence give one a certain perspective. I remember back when genetic engineering and knowledge about the processes behind aging were still in their infancy. Oh, how people argued and protested. “It’s unethical!” “We’ll kill the Earth if there’s no death!” “Immortal people won’t be motivated to do anything! We’ll become a useless civilization living under our AI overlords!” I believed back then, and now I know. Their concerns had no ground to stand on. Eternal life isn’t even remarkable anymore, but being among its architects and early believers still garners respect from the world. The elegance of my team’s solution continues to fill me with pride. We didn’t just halt aging; we mastered it. My cellular 70 MJ25-back_fiction.indd 84 machinery hums with an efficiency that would make evolution herself jealous. Those early protesters—bless their mortal, no-longerbeating hearts—never grasped the biological imperative of what we were doing. Nature had already created functionally immortal organisms—the hydra, certain jellyfish species, even some plants. We simply perfected what evolution had sketched out. The supposed ethical concerns melted away once people understood that we weren’t defying nature. We were fulfilling its potential. Today, those who did not want to be immortal aren’t around. Simple as that. Those who are here do care about the planet more than ever! There are almost no diseases, and we’re all very productive people. Young adults—or should I say young-looking adults—are naturally restless and energetic. And with all this life, you have the added benefit of not wasting your time on a career you might hate! You get to try different things and find out what you’re really good at and where you’re appreciated! Life is not short! Resources are plentiful! Of course, biological immortality doesn’t equal invincibility. People still die. Just not very often. My colleagues in materials science developed our modern protective exoskeletons. They’re elegant solutions, though I prefer to rely on my enhanced reflexes and reinforced skeletal structure most days. The population concerns proved mathematically unfounded. Stable reproduction rates emerged naturally once people realized they had unlimited time to start families. I’ve had four sets of children across 6,000 years, each born when I felt truly ready to pass on another iteration of my accumulated knowledge. With more life, people have much more patience. Now we are on to bigger and more ambitious projects. We conquered survival of individuals. The next step: survival of our species in this universe. The sun’s eventual death poses an interesting challenge, but nothing we can’t handle. We have colonized five planets and two moons in our solar system, and we will colonize more. Humanity will adapt to whatever environment we encounter. That’s what we do. My ancient motorcycle remains my favorite indulgence. I love taking it for long cruises on the old Earth roads that remain intact. The neural interface is state-of-the-art, of course. But mostly I keep it because it reminds me of earlier times, when we thought death was inevitable and life was limited to a single planet. The future stretches out before us like an infinity I helped create—yet another masterpiece in the eternal gallery of human evolution. Martin feels better after writing it out. He rereads it a couple times, feels even better. Then he has the idea to send his writing to the department administrator. He asks her to create a new tab on his lab page, titled “Immortality Promise,” and to post his piece there. That will get his message across to Sophie and everyone at Abyssinian. 71 4/1/25 12:3 PM Real-time tech conversations with the experts. “Like having coffee with Einstein” Subscribers have full access to our awardwinning journalism with Roundtables, a subscriber-only online events series that keeps you informed on what’s next in emerging tech in just 30 minutes.

Untitled-3 1 /5/24 11: 3 M 86 Fiction Sophie’s boss, Ray, is the first to email her. The subject line: “martn” [sic]. No further words in the body. Ray is known to be short and blunt in all his communications, but his meaning is always clear. They’ve had enough conversations about Martin by then. She is already in the process of slowly shutting down his projects, has been ignoring his texts and calls because of this. Now she has to move even faster. 72 Sophie leaves her office and goes into the lab. As an executive, she is not expected to do experiments, but watching a thousand tiny worms crawl across their agar plates soothes her. Each of the ones she now looks at carries a fluorescent marker she designed to track mitochondrial dynamics during aging. The green glow pulses with their movements, like stars blinking in a microscopic galaxy. She spent years developing this strain of C. elegans, carefully selecting for longevity without sacrificing health. The worms that lived longest weren’t always the healthiest—a truth about aging that seemed to elude Martin. Those worms taught her more about the genuine complexity of aging. Just last week, she observed something unexpected: The mitochondrial networks in her long-lived strains showed subtle patterns of reorganization never documented before. The discovery felt intimate, like being trusted with a secret. “How are things looking?” Jerry appears beside her. “That new strain expressing the dual markers?” Sophie nods, adjusting the focus. “Look at this network pattern. It’s different from anything in the literature.” She shifts aside so Jerry can see. This is what she loves about science: the genuine puzzles, the patient observation, the slow accumulation of knowledge that, while far removed from a specific application, could someday help people age with dignity. “Beautiful,” Jerry murmurs. He straightens. “I heard about Martin’s … post.” Sophie closes her eyes for a moment, the image of the mitochondrial networks still floating in her vision. She’s read Martin’s “Immortality Promise” piece three times, each more painful than the last. Not because of its grandiose claims—those were comically disconnected from reality—but because of what it’s revealed about her husband. The writing pulsed with a frightening certainty, a complete absence of doubt or wonder. Gone was the scientist who once spent many lively evenings debating with her about the evolutionary purpose of aging, who delighted in being proved wrong because it meant learning something new. 73 She sees in his words a man who has abandoned the fundamental principles of science. His piece reads like a religious text or science fiction story, casting himself as the hero. He isn’t pursuing research anymore. He hasn’t been for a long time. She wonders how and when he arrived there. The change in Martin didn’t take place overnight. It was gradual, almost imperceptible—not unlike watching someone age. It wasn’t easy to notice if you saw the person every day; Sophie feels guilty for 74 MJ25-back_fiction.indd 86 not noticing. Then again, she read a new study out a few months ago from Stanford researchers that found people do not age linearly but in spurts—specifically, around 44 and 60. Shifts in the body lead to sudden accelerations of change. If she’s honest with herself, she knew this was happening to Martin, to their relationship. But she chose to ignore it, give other problems precedence. Now it is too late. Maybe if she’d addressed the conditions right before the spike—but how? wasn’t it inevitable?—he would not have gone from scientist to fanatic. “You’re giving the keynote at next month’s Gordon conference,” Jerry reminds her, pulling her back to reality. “Don’t let this overshadow that.” She manages a small smile. Her work has always been methodical, built on careful observation and respect for the fundamental mysteries of biology. The keynote speech represents more than five years of research: countless hours of guiding her teams, of exciting discussions among her peers, of watching worms age and die, of documenting every detail of their cellular changes. It is one of the biggest honors of her career. There is poetry in it, she thinks—in the collisions between discoveries and failures. 75 The knock on her office door comes at 2:45. Linda from HR, right on schedule. Sophie walks with her to conference room B2, two floors below, where Martin’s group resides. Through the glass walls of each lab, they see scientists working at their benches. One adjusts a microscope’s focus. Another pipettes clear liquid into rows of tubes. Three researchers point at data on a screen. Each person is investigating some aspect of aging, one careful experiment at a time. The work will continue, with or without Martin. In the conference room, Sophie opens her laptop and pulls up the folder of evidence. She has been collecting it for months. Martin’s emails to colleagues, complaints from collaborators and direct reports, and finally, his “Immortality Promise” piece. The documentation is thorough, organized chronologically. She has labeled each file with dates and brief descriptions, as she would for any other data. 76 Martin walks in at 3:00. Linda from HR shifts in her chair. Sophie is the one to hand the papers over to Martin; this much she owes him. They contain words like “termination” and “effective immediately.” Martin’s face complicates itself when he looks them over. Sophie hands over a pen and he signs quickly. He stands, adjusts his shirt cuffs, and walks to the door. He turns back. “I’ll prove you wrong,” he says, looking at Sophie. But what stands out to her is the crack in his voice on the last word. Sophie watches him leave. She picks up the signed papers and hands them to Linda, and then walks out herself. 77 Alexandra Chang is the author of Days of Distraction and Tomb Sweeping and is a National Book Foundation 5 under 35 honoree.

Untitled-4 1 3/2 /25 12:22 PM China’s disillusioned youth look to DeepSeek to tell them what the future holds. Major buzz surrounds China’s Manus, allegedly the world’s first general AI agent. The tiny village where DeepSeek founder Liang Wenfeng grew up has become a major tourist destination in China. Robotruck startup Waabi says its simulations are now accurate enough to prove the safety of its driverless big rigs without extensive testing on real roads. A new Google AI is designed to help scientists research complex topics, but experts aren’t convinced that it’s trustworthy enough to use. DOOM Donald Trump shared an AI-generated video reimagining Gaza as a beach resort, complete with voluptuous, bearded belly dancers. Good news— Stanford researchers have developed new benchmarks to help reduce bias in AI models, potentially making them fairer and less likely to cause harm. OpenAI calls for a US ban on models from the People’s Republic of China— including those made by archrival DeepSeek. Google’s new model Gemini Robotics could make robots more useful by getting them to respond to verbal commands. Novelists, beware: OpenAI claims to have created a new model with a flair for creative writing. Elon Musk’s DOGE claims that its workautomating chatbot eliminates the need for many federal employees. The days of obsessing over manually writing and debugging are over; it’s time to start “vibe coding” instead. Checkmate! The more sophisticated an AI reasoning model, the more likely it is to cheat at chess. AI companion site Botify is hosting underage celebrity chatbots that engage in sexually charged conversations. Israel has created a powerful AI spying tool trained on intercepted Palestinian data. HYPE REALITY The AI Hype Index Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-aglance summary of everything you need to know about the state of the industry. While AI models are certainly capable of creating interesting and sometimes entertaining material, their output isn’t necessarily useful. Google DeepMind is hoping that its new robotics model could make machines more receptive to verbal commands, paving the way for us to simply speak orders to them aloud. Elsewhere, the Chinese startup Monica has created Manus, which it claims is the very first general AI agent to complete truly useful tasks. And burnt-out coders are allowing AI to take the wheel entirely in a new practice dubbed “vibe coding.” MIT Technology Review (ISSN 1099-274X), May/June 2025 issue, Reg.
