In the evening we friends were discussing AI. As the black coffee from large beer mugs started to pour in, it was getting more and more interesting. A whole lot of different ideas and views surfaced. It was really a great time, one of the best coffee time chats in a long long time. Few of the points that I inferred..........
Intelligent machines may be within the technological reach of the next century. Over the next few generations we'll have to face the problems they pose. Unless some unforeseen obstacles appear, our mind-engineering skills could grow to the point of enabling us to construct accomplished artificial scientists, artists, composers, and personal companions. Is AI merely another advance in technology, or is it a turning point in human evolution that should be a focus of discussion and planning by all mankind? The prospect of intelligent machines is one that we're ill prepared to think about, because it raises such unusual moral, social, artistic, philosophical, and religious issues. Are we obliged to treat artificial intelligences as sentient beings? Should they have rights? And what should we do when there remains no real need for honest work, when artificial workers can do everything from mining, fanning, medicine, and manufacturing all the way to house cleaning? Must our lives then drift into pointless restlessness and all our social schemes disintegrate?
These questions have been discussed most thoughtfully in the literary works of such writers as Isaac Asimov, Gregory Benford, Arthur C. Clarke, Frederick Pohl, and Jack Williamson, who all tried to imagine how such presences might change the aspirations of humanity. Some optimistic futurists maintain that once we've satisfied all our worldly needs, we might then turn to the worlds of the mind. But consider how that enterprise itself would be affected by the presence of those artificial mindlike entities. That same AI technology would offer ways to modify the hardware of our brains and thus to endlessly extend the mental worlds we could explore.
You might ask why this essay mixes both computers and psychology. The reason is that though we'd like to talk about making intelligent machines, people are the only such intelligence we can imitate or study now. One trouble, though, is that we still don't know enough about how people work! Does this mean that we can't develop smart machines before we get some better theories of psychology? Not necessarily. There certainly could be ways to make very smart machines based on principles that our brains do not use, as in the case of those very fast, dumb chess machines. But since we're the first very smart machines to have evolved, we just might represent one of the simplest ways!
But, you might object, there's more to a human mind than merely intellect. What about emotion, intuition, courage, inspiration, creativity, and so forth. Surely it would be easier simply to understand intelligence than to try to analyze all those other aspects of our personalities! Not so, I maintain, because traditional distinctions like those between logic and intuition, between intellect and emotion, unwisely try to separate knowledge and meaning from purpose and intention. In The Society of Mind, I argue that little can be done without combining elements of both. Furthermore, when we put them together, it becomes easier, rather than harder, to understand such matters, because, though there are many kinds of questions, the answers to each of them illuminate the rest. Many people firmly believe that computers, by their nature, lack such admirable human qualities as imagination, sympathy, and creativity. Computers, so that opinion goes, can be only logical and literal. Because they can't make new ideas, intelligent machines lie, if at all, in futures too remote for concern. However, we have to be wary of such words as "creativity." We may only mislead ourselves when we ask our machines to do those things that we admire most. No one could deny that our machines, as we know them today, lack many useful qualities that we take for granted in ourselves. But it may be wrong to seek the sources of those qualities in the exceptional performances we see in our cultural heroes. Instead, we ought to look more carefully at what we ordinary people do: the things we call common sense and scarcely ever consider at all. Experience has shown that science frequently develops most fruitfully once we learn to examine the things that seem the simplest, instead of those that seem the most mysterious.
