Good point. The rate of cognitive improvements would be slow, imperceptible even over many generations, and virtually non-existent over the less than 100 years of digital automation.

It would be interesting to know how much we changed cognitively since our species bifurcated, and also since civilization scaled up social density.

Relative to the discussion, AI tech is progressing in time frames that are a fraction of a human generation. So we are at a complete standstill in that context.
