TL;DR CRISPR will lead to fewer people on autism/spectrum?

A friend mentioned his son is a bit "Aspy" - he said it with a bit of pride in his voice. Both father and son are brilliant coders.

Meanwhile, there's Modafinil. Originally intended as a treatment for narcolepsy, others use it to improve concentration.

I wonder if neuro-configurability will lead to less or more diversity?
