I'm sure that is part of the hiring disparity among females and underrepresented minorities. As a black guy myself, I know the same is true among black people who simply aren't interested in engineering but Damon makes weird ability judgements based on the population.
This makes no sense as people with different interests would never bother in the first place no matter how much time and money you threw at them. So again I say why bring up the upstream problem to begin with as it being related to their abilities for engineering?
IMO, the only way his text makes sense is if you are someone looking to back up potentially racist and sexist biases by misusing science. It makes me question their ability to work with people different than themselves.
With that said I'm actually torn on the issue of the firing. Google says its a place for diversity of opinion etc etc...So on some level they should stick by it.
However, I understand why the firing may have needed to be done. The fact that a low level employee made the news for being controversial means you have to be fired. You can't send a memo out like that and expect there to be no career consequences at your company of employment. You will never be able to live it down.
