Capilano University The Intelligent Machine Can Computer Think? Rio Jeremy 100022638 Philosophy 102 Dr. Martin Godwyn March 31, 2012 1511 Words Jeremy 2 Can a computer think? One might says it cannot since it is only a machine. However I argue that it is correct to think that computer can actually think like human does. To do that I will appropriately argue first by defining the word ‘think’ as we understand it, then address the skeptic argument with the three-stage model, followed by the common examples of intelligence within a computer nowadays, and finally talks about Alan Turing and the impact of his paper whiles at the same time providing enough examples to back the claim that computer indeed can think. Today, we have advance machines or computers that can play tennis, translate language, have conversation with a human, solve mathematical problems, and so much more. This phenomenon begs the question that been around us for a while, “In principle, can a digital computer think?” I believe that yes indeed, in principle they can think. In this paper, I will explain thoroughly while raising certain points about why I believe that computer can think. First, we will define what is the meaning of the word ‘think’ for our base argument, then we will look at the three-stage model I developed, address the issue of the skeptic, and finally we will talk about Alan Turing and how his test prove to be relevant while at the same time giving examples of nowadays technology. Using Merriam-Webster dictionary, to ‘think’ is to have a mind. So when somebody ask “What is two multiply by two?” one tend to ‘think’ by calculating inside the head and answer “four”. When one ask the same question to a computer, it will be able to answer just as quickly if not quicker. So does the computer can also think? The skeptic might says no because the computer can answer that simply because it was programmed to answer that. But how about one self? How can one answer the question in the first place without being ‘programmed’ by the teacher teaching mathematics? It is practically the same. Another example would be a new-born baby. Can such a being survives without getting supervised by an adult who is more ‘advance’ in Jeremy 3 terms of development and survival skill? A baby will certainly feel hunger and will show it in tears and cry however they do not know why they are crying and how to overcome this feeling of hunger. By constant feeding from the parents, the baby soon realized the key aspects of life. This whole process of learning is similar if not the same by principle to a computer program. When the baby does not know why they are hungry, they are like error messages in a computer. They do not know how to solve it until they encounter it, and could not find the solution by itself (for human, the parents must taught the baby how to tackle the problem of hunger by giving food and for computer, the developer must intervene to let the computer knows what is the solution for the problem). People experienced with computers might say that computer cannot think and only be able to follow a rule book. The outline for a computer is brought to a simple three-stage model: input, process, and output. If we are able to see computers using this simplistic model, we ought to accept a simple model of the human mind as well. For computer, the input devices are keyboard, mouse, and many other devices. For human, our sensory inputs of touch, hearing, sight, taste, and smell are our input devices, without these there are nothing for our mind to consider. From these input devices, information is supplied to the central processing unit, or to the mind respectively. Then the processing unit for the computer and the mind for human, analyzes the information given by the inputs and concludes to determine what action is necessary. For example, if one see and smell a peanut, one must determine whether to eat it or not given the circumstances based on the surrounding and already known knowledge such as an allergy, then in the end one decides not to. This is the output that the processing unit in a computer or the mind in a human generates. It could be a physical means, using the power of the Jeremy 4 body, or just storing the conclusion in the databank (memory) for future use. Using this simple three-stage model, the mind essentially operates in exactly the same way as the computer. We can assume that when a computer process an input into an output, it is the same way as a human thinking whether or not to eat the peanut as previously mentioned, in other words we can safely say that we are able to tell when a computer thinks. Does this means we can simulate human beings by using the simple three-stage model? The skeptic would probably say no because the complexity of human being in terms of intelligent cannot be perform by artificial intelligent. However, the car manufacturer Honda build a humanoid robot as early as in 1986, it is called ASIMO. Since then, Honda keep developing the robot as we speak right now. ASIMO can run, walk on uneven slopes and surfaces, climb stairs, and comprehend many questions as would a normal human being can (Hornyak 104). What is significant about ASIMO is its ability to recognize objects, gestures, and sound; ASIMO will give a handshake to an outstretched hand, respond when its called, and more importantly, work out the identity of an unfamiliar object by comparing it to similar items in its memory banks. Does playing chess require intelligence? Many would argue that intelligence is needed to be able to play chess let alone good at it. Gary Kasparov is a former world champion in chess, he won the 1984 world championship and successfully defended his title until 1993 (Kasparov 1). The giant American computing company IBM developed a chess-playing computer called the Deep Blue. In 1997, Kasparov was beaten by the Deep blue in chess match showing its intelligence at chess. There are many more examples for this type of intelligence in a computer based program that shows the level of intelligence in a computer. For example, an intelligent person might be able to translate a language, but so does Google Translate. Intelligent acquired by human are Jeremy 5 thought to be earned from studying the patterns over time and actually becomes better at that particular thing, however if the computers can do all those things mentioned above, we should consider that a computer might have the intelligence within it. Alan Turing is a well-known scientist that wrote his radical paper “Computing Machinery and Intelligence” and came up with a test called the Turing Test. In a nutshell, the Turing Test was a simple test which shows a computer having a conversation with a human being. The objective of the test was to show that if the computer could make the interrogator thinks that he was talking to another human being instead of a machine, then the artificial intelligence pass the test. However, Turing is very careful to explain that his test is about imitating human mind, not the human itself: “We do not wish to penalize the machine for its inability to shine in beauty competitions, nor to penalize a man for losing in a race against an aeroplane” (Turing 2). When Turing wrote his paper in 1950, he believes that in 50 year time, approximately at the turn of the century, future artificial intelligence will be able to pass the test. Indeed his prediction sort of came true when the bronze award won by an A.I named ALICE in the annual competition of Loebner Prize. Nowadays with technological advancement that we experienced, we as human has created many amazing computers that have human-like intelligence. Quick example comes to mind is Apple.Inc’s great software called Siri. Siri is a software capable of answering questions, make recommendation, and perform action within its device whiles at the same time adapt to the user’s personal preferences over time and personalized its result during its course (Sadun 1). From the development of computing based technology we can see that computer will prosper and develops even more rapidly to become one of the greatest invention of human kind. Jeremy 6 To conclude, being a functionalist I think that human mind is an advanced computer. We can see from our examples mentioned above, computers can perform just as human can. The human mind contains ‘hardware’ and ‘software’ just like a computer. The hardware for human is the electro chemical pathways and neurons in the brain whereas in the computer it is the wires, CPU, and motherboard to name a few. Both human mind and computer have the software which is the program within our brain. A computer takes and execute programs, this is what the human mind does eventually but on a more complex level. People will say that a computer lacks the capability to understand but how do we know it does not? Jack Copeland who wrote and edited books on Alan Turing says in his book Artificial Intelligence: A philosophical Introduction that machine as a whole will understand but take individual parts and it will not (209). This is the same in the our human brain, if one take a single neuron out of our brain, it will understand nothing when if one leave the single neuron to be part of nerve system as a whole it will understand. Having said that, I believe that computer are able to think just like human does and the human mind is just a complex computer to say the least. Jeremy Works Cited Copeland, Jack.
