I didn't say we need 50% of technology workers to be women. But I am saying that sexism is not yet a solved issue in education or in the tech industry, and I think it's reducing the number of women in the field. I'm open to the possibility that when sexism is not an issue in education or in technology work, women still pursue the field less often than men do on average.
But we're not there yet. We have women losing interest in the field at school and especially dropping out of careers because of discrimination, harassment, and other similar treatment. And that kind of thing has a ripple effect - fewer mentors for other women interested in the field are available, and there are stories of mistreatment.
So the value of many of Damore's points are undercut by that. He points out that women are more vulnerable to stress. Enduring sex-based harassment and mistreatment while most of your colleagues do not would cause additional stress, so how many women with stress problems are simply more susceptible to stress and how many are in fact reacting the same way a man would to higher stress in their environment? I don't know the answer, but he doesn't even raise the possibility.
Damore points out that women tend to focus more on work and life balance for the sake of family, and it hurts their career prospects. But there again, I took plenty of time off for the birth of my kids and my male colleagues with children did the same, and we rearrange our work schedules for medical appointments, award ceremonies, recitals, chaperoning field trips, etc... and nobody ever used that as an excuse to deny us a raise or give a promotion to someone else. So how many women with a faltering career due to a work and life balance are actually just being punished for being women, while their male colleagues with the same balance climb the ranks?
And again, there are enough stories of harassment and sexual harassment floating around that I'm confident some portion are true. I'm sure some are fabricated and some are exaggerated, but hysterical theatrics aren't restricted to women - I've worked with delusional narcissistic men too. Most likely, a big portion of those accusations hold up - and that means a lot of people are being driven out for reasons wholly unrelated to intelligence, competence, and work ethic.
We're not even a hundred years out from women's suffrage in most of the world. It's too early to call this topic settled.
