Tech people were never very intelligent. By definition, they were (and are) informed/educated in one specific discipline, but that has no correlation whatsoever with being intelligent.
This is true regardless of the discipline. You can meet astoundingly stupid heart surgeons, astrophysics PhDs, etc.
"Yes, it's true: I am a rocket scientist" often quothe one of the stupidest persons I have had the opportunity to meet on this ball of dirt, because he had a PhD in aerospace engineering.
That said - he was good looking, had a reasonably good sense of humor and knew where the good parties were - so he could be forgiven this small vanity.
