The limiting factor is breeding rate. Nobody has time to wait to run this experiment for generations (chimpanzee or human ones). ML models evolve orders of magnitude faster.

Ah. Well that's easy enough to sort. We just need to introduce some practical limit to AI breeding. Perhaps some virtual score keeping system similar to money and an AI dating scene with a high standard for having it.

I'm only half joking.

Let humans plug into it to get a peek at statistical distribution of their own prospects, and I think there was a Black Mirror episode just about that.
