I would suggest you work in tech for a while, some of the best engineers I have ever worked with are women.  So, yeah, it is a troglodyte attitude to believe that when it comes to engineering, that women just can't hack it.  I will agree that there are some things that either men or women aren't suited to because of biology, child birth is one and I can't think of many women who could ever get big enough to be on the O-line for a football team.  However, when it comes to jobs that require brains, you seem to be suggesting that women may not be able to do the same jobs as men.
