There's absolutely no evidence of any 'biological realities' that somehow make women less inclined to want or able to do computers, math, or anything else STEMy. There is plenty of evidence of attitudes like those of the guy in the OP being widespread in STEM - especially in IT, for some reason despite programming being considerably less difficult than, say, hard sciences - which might make the prospect distinctly off-putting, though. So, is it some mysterious "biological difference" that we've never seen evidence or even have a hypothetical mechanism for, or is it that the tech industry is full of fucking assholes who think you need to possess some sort of god-like level intellect unobtainable by woman in order to do a bit of Java?
