The French urologist by day eugenicist transhumanist crank by night Laurent Alexandre had an interesting perspective on the subject fifteen years ago. We should do eugenics and edit our brains to be better so as to counter the emergence of Artificial Intelligence. The robots will replace us if we don't do rigorous embryo selection.

Incidentally he also warns that a modern day Stalin in possession of neuromachines and gene editing technologies would create what he terms "neuro-gulags".

I don't remember seeing Lesswrongers play with these sorts of ideas, which is a little surprising. But they're reluctant to diminish the AI's omnipotence I imagine.
