Social Implications of AI
• Elimination of jobs
• Replacing human judgment by machine
judgment
• Altering our understanding of ourselves

Consider Computers that are
More Intelligent than Humans
• Suppose it’s impossible
– establishing this would require some kind of scientific
proof that a computer cannot emulate a brain, or that a
brain is not sufficient for intelligence
– in either case, a major scientific breakthrough
• Suppose it’s possible
– could displace us in all intellectual activities
– if we had nothing to do, what would it mean to be
human?
– would/should humans be obsolete?

Promethean Fire
• “All technology is non-neutral”
• Computer technology has:
– social benefits
– social costs
• Often, issues are not peculiar to computers,
but are amplified by computer technology
• Sometimes problems arise from using
computers as they are intended to be used

Uses of Personal Data
• Marketing
• Decision making
• Other uses:
– secondary use
– invisible information gathering
– information from children

Simulation & Models
• Recall our discussion of models:
– a model is intended to address a certain class of
questions or issues
– models make simplifying assumptions
• Recall the omission of aerodynamic
stability from bridge models before the
Tacoma Narrows Bridge disaster
• Nevertheless, computer models &
simulations are essential

Evaluating Models
• How well is the underlying science
understood?
• What sorts of simplifying assumptions are
made?
• How well does the model agree with
experimental results?

Computer Crime
• Often just a new or “better” way to commit
traditional crimes
• Ampliative aspects of computer technology
– may allow committing crimes on a larger scale
• Reductive aspects of computer technology
– may make it harder to detect crimes, identify
criminals, etc.

Some Kinds of Computer Crime
• Fraud, embezzlement & theft
• Stealing (data)
• “Hacking” (system cracking)
– individual systems
– the information infrastructure
– benign hacking?
• Viruses & worms: reproduce selves
– virus: hides in another program
– worm: an independent program

Constitutional & Civil Liberties
Issues
• 1st Amendment protects freedom of speech
& press
• 4th Amendment protects against
unreasonable search & seizure
• Do they apply to electronic & other new
media?
• So far, the courts generally have held them
to apply, but there is much uncertainty

Communication Media
• Is the operator of a communication medium
responsible for the information it carries?
– analogy: telephone companies & post office
– analogy: a privately-owned meeting room
• Can the operator restrict this information?
– analogy: telephone companies & post office
– analogy: private presses

Encryption & Wiretapping
• Encryption can be used to ensure privacy &
authenticity
– may be used for legal/illegal purposes
• May be subject to export restrictions
• What provisions should be made for
government interception & recording of
communications?
• What limits should be imposed on the
government
