My point is that due to its representation of human knowledge, Cyc is particularly interesting (to me, obviously) and a good idea; it has produced useful and interesting results and is something that is sorely needed for work with natural language. >But we would probably learn more about the fundamental principles underlying >intelligence PER SE if we could model a beetle. Might be useful for certain applications, e.g. entomology, ecology, biosystem dynamics. A major problem with AI systems to date has been their highly specialized nature, the worst example being "expert systems" which solve specialized problems quite well, but are really shallow and brittle: the information encoded in them is highly specialized and lacks connections to more generalized information. As a result, they perform poorly outside their specific domain, and do not interact synergistically with other, similar, specialized systems. Cyc provides a framework of general knowledge and common-sense reasoning, which more specialized systems could be built on top of and into. Such systems would be able to handle problems in a variety of domains, at multiple levels, and translate between them. > Having done that, we >can then move on to a Beatle, say Ringo. Cyc probably has the advantage, because it already has information on the domain of human general knowledge. The Beetle-system would have information on the insect world (e.g. insect foods, predators, smells, self-defense, mound construction, etc.) which would not be terribly useful to Ringo (even if he has been reduced to doing Sun Country wine-cooler ads...) It's possible that some of the thought processes (e.g. eat when you're hungry, fight or flee) might be useful to him, but more sophisticated reasoning (e.g. sue people who violate your copyright :-)) would have to be incorporated to make the Beatle system useful.
