I mean I get that the sex discrimination stuff and treatment of women we read here on hacker news is bad and of course it would help if there were more women in tech.
But other than that, if you think of the women in general and not some "diversity would be good" (which it probably would be), why the worry?
Why aren't we as worried that not enough men show interest in being nurses or kindergarten teachers or social workers? I know from experience that it would be very important to get a more "balanced" look at things in those fields.
Are we still treating women as little girls who we need to be worried about because they "only like superficial things and nail polish" and can't really take care of themselves unless we make changes so that "important stuff" is more attractive to them? I think this is a very patronizing attitude, and dismissing the stuff some women may find more interesting than "hard sciences"
