I think you might have misunderstood my point.

The OP was asking why, in a world where AI can think smarter and faster than humans and thus do everything a human could do but better, would humans do anything at all? I was pointing out that, pragmatically speaking, that’s already the case- plenty of people do activities they’re not the best at because the act itself is what brings enjoyment.

Using OP’s logic, because Michael Jordan is the greatest basketball player (or Chamberlain, or Bryant, or James, or insert whoever you think is the best) no one should be motivated to play basketball. And yet, lots of people still do, which means his premise- that people are only motivated to do things either because they’re the best at it or they can meaningfully advance the field- must be flawed.
