Why the 'Women in Tech' Problem May Actually Be a Silicon Valley Problem

The sexism is everywhere. However, the brogrammer culture which has made an art of condescending to women PLUS all that PUA bs, is quite specific to SV and may even be an SV export (when I have seen it outside SV, it tends to a derivative).
In some other places they just treat women like shit outright without writing long articles about it :) (Like the founder who told me he was going to have a wet dream about me, after I kicked him out of a startup competition he sucked at.)
It is more likely to be an SV power thing where the nerds finally get to talk to women and only see them as objects.
Women have always been in finance (not limited to Wall St.) as even though trading is glamorous but commercial/retail banking employs a very large number of developers for boring CRUD jobs, as customer service personnel, backoffice and middle-back-office type work.
So women being treated better in the finance sector is more not less likely.
