There are still some major irrational points that I see:
- Bias (conscious and not) is assumed to be a problem mainly perpetuated by white men, when reality is that, for example, women may have as much or more bias toward women than men do. I.e. the factor of women enforcing gender roles among themselves is dismissed.
- The success of white men in startups is assumed to be caused by them excluding others, rather than because they share a culture with each other from an early age with a lot of positive characteristics. Saying we excluded girls from programming and chess teams, or from spending long hours alone at a computer instead of socializing, is at least an oversimplification.
- Men being attracted to things and systems and tinkering vs socializing and people is real. It's more than a standard deviation (i.e. differences between groups are more than differences between average individuals), it starts hours after birth, it correlates to pre-natal testosterone levels, it happens across species. Scientifically it's a slam dunk and it is a pretty plausible hypothesis for why women are poorly represented in coding positions, compared to other equally demanding jobs, e.g. doctors and lawyers where women are doing just fine.
