Maybe you'd find more role models if you didn't segregate by gender (that's sexist, after all). If you can only look up to people who share your genitalia then I think that's pretty limiting.
I don't think I'm asking for too much by wanting a woman in tech to look up to ¯\_(ツ)_/¯ it's not sexist dude, I just want some representation in my role models.
I mean, apart from everything else in this thread, Marissa Mayer doesn't really seem to have done much: a good management role in Google, tanking a former internet giant and getting a lot of money for it, and setting up a company that doesn't seem to have produced anything so far.
Even if you look for women role model in tech, is it possible there aren't any more successful ones?
