No, he's sort of right. He extrapolates a bit and makes it sound much worse than it was. For someone who is claiming to understand engineering so well it seems odd that he'd conflate arguments (that were poorly made imo) about preferences within a demographic group with accusing that group of being inferior at engineering. He never suggested women were bad at their jobs, just that maybe there was a biological component to why they were less interested in it to begin with.

Edit: just to reiterate, I don't agree with that view, I'm convinced it's mostly cultural issues that are to blame.
