Those who work in tech seem to share similar personality types, which in genetics works to reinforce certain traits, as well as to bring out other defects.

I've had this notion about autism as well. More then ever people with highly analytic detail oriented minds are breeding in elite circles and some of these minds might be producing defects as a result of the heavy cognitive specialization. We know the Ashkenazim have higher rates of schizophrenia. Imagine if it came out that geniuses should be weary of mating with eachother? That would be fascinating. I've always thought that we should pair the brightest male minds with the finest genetic female specimens. A harem of Olympic female pole vaulters for each and every great male mind. Assuming they are nationalist moral geniuses and not evil subversive geniuses.
