So far as Densmore's actual suggestions go, at least one, that women want more work/life balance, and making positions with more flexibility will be more attractive to women, seems pretty uncontroversial. It's exactly what many feminists have been saying for years.
Competitive vs cooperative - I think many would agree with that too. If anyone has read Kathleen Stock's essay about changes in philosophy departments over the years, making them less adversarial and more cooperative is something that was also pushed as making them more friendly to women.
Personally, I also think that he is right that on balance, more women want to be in work that involves a certain amount of human interaction, compared to men.
He also talks about women being less likely to pursue promotion and raises a little, which is uncontroversial and something often mentioned on FWR.
One thing that strikes me, is that for those women who do go into tech, as well as many of the men, changes to the whole workplace culture might actually undermine the things they like about that type of work. I studied philosophy at university around the same time Stock did, and then worked in a very male dominated sector for years. A lot of what I liked about working in those places were some of the things that Stock mentioned had changed in philosophy departments to make them more amenable to women.
That doesn't necessarily mean they would be bad changes at a place like Google, but I do wonder about the - I guess you could call them moral or ethical questions? - trade off of people who like to work in certain types of environments (who happen to be weighted towards men), vs less of that personality type but more women.
If we flipped it, and said men on average are less interested in a certain type of work, so we should change it to be more amenable to the average male personality, but this might make it less amenable to some women - would we think that was a good trade off?
