Your point about possible stable equilibria I don't have any beef with. But honestly I think the “problem” is more on the supply than the demand side. Fewer women find engineering/technology attractive than men. Women have better options given their preferences than tech.

Normally this would be where I linked to the Study of Mathematically Precocious Youth paper showing girls who entered math competitions withr similarly skilled boys to leak out of the tech/science/engineering path much more but I'm on my phone.

Bowing out.
