I don't think the real problem is with the idea of auto-adaptiveness but with the implementations and their faulty assumptions. E.g. I have one computer that I bring out maybe once a month at parties. It should not think: "Okay, he hasn't used these playlists for a month, we can hide them." Some computers are also shared between many users (using the same account), so the adaptation logic would have to somehow realize that. And so on. I think Apple is wise in not trying to do something like this until it can be done right. When it's done right, the user will never even realize it. Everything will just seem even smoother and simpler than before.
