That doesn't mean that all women are participating in "knowledge work" jobs though. K-12 education and healthcare are also two fast growing sectors that have a high proportion of female workers. I doubt that all jobs in those sectors should be considered "knowledge work".
Participation stats for women could also be due to sectors like HR, or just generic office work. Obviously I don't deny the existence of female programmers and scientists. I just don't think there's evidence to suggest that they can do those jobs strictly better than men can.

I think this is plausible.
