"Either there is something in the way we as a society and industry educate, hire, manage, and promote women".

I would add raise and socialize as kids to the list, but to me that's clearly part of it.

The entire evolution of a person from baby to adult is moulded by society, which makes it pretty ridiculous when the enlightened techies want to solve the lack of women in tech by only "fixing" hiring and promoting. And management, if we're feeling generous.
