I think we've been in the trance of possibility—of just doing things that are possible because they're possible—for a while now.
When it comes to intelligence, maybe there's a scenario where humans are useful, and they herd us like cattle, or they have us as pets because we happen to be pleasant. Maybe we're not pleasant. Maybe we're like cockroaches. Your guess is as good as mine. But just thinking of the power relationship should give you an idea that it might not be what we would call a good human life.
