I suspect the bait-and-switch wouldn't be such an issue in a more sexually equal environment. Physicians are about 50:50 and while I've heard plenty of female doctors complain about being called "nurse", I've never heard a complaint about "bait-and-switch". I have heard a few complaints about "where'd all the men go?"

The environment in tech sounds about like the military: women have to be prepared to physically fight their own team. Which is deeply unfortunate.
