Personally I think its great to see more women in the sciences, engineering, and technology sectors.
I think there are a lot of elements at play here. The environmental factors as previous posters have pointed out are big. There's a lot of cultural issues with how math, science and technology are perceived and how they are encouraged to both developing males and females.
Certainly I remember when learning programming when I was young that programming was a thing "only for white pale nerds with glasses who played doom, had no hygiene and no social skills". It might be somewhat true still, but no doubt computers are no longer the domain of "Dungeons and Dragons" fans.
Also I think societal values have changed for the better. Half a decade ago, women were encouraged to (dare I say it), stay in the kitchen, do the ironing, and feed the children while Joe husband did the bread-winning and brought home the bacon.
Nowadays women are encouraged to have careers and ambitions outside of being a homemaker and many actually want them, which is why we the diversity and change that we see in the world today.
As for women becoming the best in some field, I think its doable, but I should point out that many people that are ahead of their time and change things often have a tendency to have certain mental prerequisites like being a workaholic, having obsessive tendencies, having some kind of mental 'disorder' whether that can include social withdrawal and isolation, perhaps some kind of eccentricity, and maybe something along the lines of paranoia, bipolar, schizophrenia, or high functioning autism. I'm not sure what the data says about how divided the population is with those traits but I'm going to make a conjecture that men have higher incidences of those traits than do women (only a conjecture!)
Of course not every person who does great things has this mental profile, but certainly when reflecting on the history of mathematics and its contributors, there certainly is some evidence of this being prevalent.
As for the evolution argument, I think this is a joke. The people that spout the "survival of the fittest" argument are missing the whole spectrum of activities that humans (and other living creatures) take part in. Why do people create things, play music, paint paintings, do charitable activities, have inner goals not revolving around survival? Although I've never actually seen an "axiomatic" definition of survival, I highly doubt that his "axiomatic" definition of survival traits includes anything I've just mentioned.
There are countless studies with many creatures including gorillas and dolphins that show the ability of creatures other than humans to demonstrate levels of empathy and actions that aren't strictly required for survival.
