Keep in mind there are many more humans that aren't as bright. If there are fewer and fewer ways for them to contribute then they'll find other ways to get what they need.
The corollary being that those people are already earning their bread doing things which an artificial intelligence can't replicate. I've seen many vast overestimates of how many of these jobs could even be replaced with a Jetsons robot, and we're nowhere close to deploying anything vaguely resembling one of those.
