The problem with humans are they don't intrepret thier perceptions right. A computor is said to be smart. Well if i look at it I'm convinced that if I give it a problem that it will give me the right answer. If I ask a human he will probably error.
There is a WORLD of difference between the answer to a mathematic equation and the feelings a human being experiences when listening to music. In terms of interpreting one's perceptions I say there is no right or wrong. I do not ask another to tell me what I should be feeling or what I should enjoy. It is not the simple solution to an equation. It is infinitely more complex, and layered, and dependent upon variables, both tangible (the space, the intruments, the temperature, etc.) and intangable (the baggage we each come with..the filters through which we perceive the world). It is a sad concept to want to break down those complexities into numbers and some concept of right and wrong.
Re: your example of cooking. Try to get a machine to prepare a gourmet meal. Again, probably someone already working on it, but I doubt it will be as effective as a master chef. Even if it were, and again, I go back to perception, how a group of individuals enjoy the final product (the food in this case) is entirely subjective and individual. There is no right or wrong there either, regardless of technique. Some folks like it, others may not.
