I don't think its some brocoder deciding he know more than everyone else, I think its a case of a smart person taking the time to lay out what years of research shows over and over again; there are biological differences between men and women that over a large population average out to a statistically significant preference for occupations.
Look at all this shit and also take heed of the fact that rather than Google explaining why he was wrong based on evidence they simply fired his ass. You can be certain that was a carefully calculated PR move.
Now the danger is that alt-right scumbags will use this as a tool to defend their shitty ideas but thats an outcome of how facts are used, the fact is still true...
The biggest mistake this guy made was to put forward a reasonable assertion backed by science and expect a reasoned discussion, that was never going to happen and his own naivety has pretty much screwed him. He should have seen it coming but that doesn't mean he deserved to be fired.
Also its pretty interesting that there is a huge desire for biological diversity under the premise that companies will benefit from new ideas, but then when an actual new idea is put forward they immediately hit they throw you out of the room.
