IV. What does it take to be human? The mind/body problem and artificial intelligence Intro: what is AI? AI is that part of computer science concerned with designing intelligent computer systems, i.e. systems that exhibit the characteristics which we associate with intelligence in human behavior e.g. understanding language, learning, reasoning, solving problems, etc. Rough definition: A system is artificially intelligent if the task the system is carrying out would require intelligence if performed by humans. In our stories, “an AI” refers to a system that is artificially intelligent 2 Main Camps in the current AI debate Proponents of strong-AI think real AI is possible Michael Arbib says, "AI programs really could exhibit understanding or intelligence, rather than simply simulate aspects of behaviors we construe as intelligent when performed by a human being." Proponents of weak-AI think the best we can do is build a computer that mimics real intelligence Can make it act as if it were sentient, although in fact it isn’t Let's start to outline the field of interest with famous argument against strong-AI: Searle’s Chinese Room Source: Argument and Analysis , 340-343. Locked in room with baskets of Chinese characters I do not understand Chinese Book of rules written in English for matching up symbols coming in through the slot Rules describe the shape of the symbols so I can pick them out of the appropriate baskets Outside there are 2 slots: In and Out Native Chinese speakers are outside They have no idea what’s going on within They slip pieces of paper with Chinese characters I check the rule book to determine which character(s) should be sent back Find the character in the baskets and send out through the other slot I don’t know it, but the people outside are putting questions through the In slot From their point of view, answers to these question are coming back This is what the writers of the rule book intended Perfect grammar and syntax for Chinese But I do not understand Chinese Analogy Chinese Room Computer You Central Processing Unit

computer housing English machine language In slot Keyboard Out slot Printer Instructions in manual Program Chinese English Rule book writers = programmers They are the only ones who know what’s going on both from the users perspective and within I.e., both inside and outside the Chinese room Point : If I don’t understand Chinese, then neither does a computer running a program Doesn’t matter how efficiently the computer responds to my questions In fact, it isn’t clear whether symbol manipulation has anything to do with true understanding at all Q: What do you think? Good argument against strong-AI?
