Yes, so can we please stop pretending that it is a travesty that few women are interested in IT?
No, because if it really turns out that what set of genitals you have play a major role in such a huge financial decision as what career you choose, even in the absence of outside coercion, then that instantly invalidates any economic theory that assumes people generally make rational (from purely economic perspective) choices - which would be all of them. Alternatively, if it turns out that career choices are affected by such coercion, for example in the form of sexism, then that is distorting the market and resulting in a needless net loss for the economy which can ill afford it, as well as continuing a tradition of power abuse humanity can afford even less. Either way, this is one subject where we really can't afford to leave any hair unsplit when searching for the answer.
Sure, let them do it if they're interested, but if they aren't interested they don't need to have their noses rubbed into it in high school with the expectation that the gender gap in that particular career field will close.
I'm not sure what you mean here. High school is general education, not vocational training. It's very purpose is to expose students to as many things as possible with the hope that they will be at least somewhat familiar with most things. And computers and programming are unlikely to become any less important anytime soon.
And it's an odd expression to use, that "they don't need to have their noses rubbed into it". Because you usually rub someone's nose into their failures or inadequecies, not mere lack of interest in something. It almost sounds like you were defending a weakling from being bullied - in other words, it sounds like you're saying girls can't program and we all should leave them alone already.
Oh well, I'm sure it was just a bad choice of words from your part and you didn't actually mean anything so ridiculously sexist.
