There is no reason to expect human universal values to be identical to chimpanzee universal values.
Sure there is- "maximize inclusive genetic fitness."
Art, for example.
Are you familiar with the theory that the human brain is essentially a peacock's tail, and that language, creative endeavors, and so on were evolved primarily to attract mating partners?
It's possible that a chimp that gets a lot smarter won't start having more intellectual tastes, but the basic problem of "who do I have sex with, and how do I get them to agree?" is still around and it seems like they would try very similar methods to what we have.
Ah, it seems we have different ideas about what human values actually are.
"maximize inclusive genetic fitness."
Organisms are adaptation-executers, not fitness-maximizers. Art is a human terminal value. Maximizing inclusive genetic fitness is not. Even if the causal reason for us having this value were that artsy people get more sex, we would value art for its own sake.
I highly recommend the wiki article on the complexity of value and the articles linked from it.
Taken from some old comments of mine that never did get a satisfactory answer.
1) One of the justifications for CEV was that extrapolating from an American in the 21st century and from Archimedes of Syracuse should give similar results. This seems to assume that change in human values over time is mostly "progress" rather than drift. Do we have any evidence for that, except saying that our modern values are "good" according to themselves, so whatever historical process led to them must have been "progress"?
2) How can anyone sincerely want to build an AI that fulfills anything except their own current, personal volition? If Eliezer wants the the AI to look at humanity and infer its best wishes for the future, why can't he task it with looking at himself and inferring his best idea to fulfill humanity's wishes? Why must this particular thing be spelled out in a document like CEV and not left to the mysterious magic of "intelligence", and what other such things are there?
