Can you not pick your preferred institution for giving birth? For our first child, we deliberately chose a hospital with a special children's unit attached, just in case (admittedly, we didn't think about special risks for the mother).
Meanwhile, other people campaign for giving birth at home, which seems crazy to me...
Actually since there are so many more men than women in tech, most things you describe happen more often to men than to women. For every women who nobody listens to in a meeting, there are ten men who nobody listens to in meetings. For every woman who doesn't get promoted there are ten men who don't get promoted - and so on (running with your example of 90% men).
Maybe sexual harassment is different, because men are less likely to make a move on other men, and if there are fewer women obviously fewer women will make moves on men than vice versa. Unfortunately the scale of sexual harassment is very difficult to gauge as so many different things are being lumped together. For some sexual harassment is "disagreeing with a woman" (as seen in a recent Pando article on YC which will not make it on HN), others have legitimate complaints. Still, why should the tech be worse than other walks of life in that regard, except for the disproportinate gender quotas? (Meaning if more men hit on less women, odds are higher for unpleasant incidents/bad apples than if less men hit on more women).
It sounds like good-natured fun, but it actually seems like an equivalent to the notorious "security competitions" - it can then be claimed that "nobody managed to write an underhanded code" like "nobody managed to break our encryption".
In any case it seems very difficult, given the scrutiny the code would probably see.
Are the sexual harassment cases related to women receiving less funding? Intuitively it might seem likely, but the recent stories have been about sexual harassment, not about likelihood of women receiving funding. It could simply be two unrelated issues - and even if they are related, VCs being sexually interested in a female founder might not decrease the likelihood of investment.
I think the "position" of power thing is often overblown. Most women are not prostitutes, so they are perfectly capable of turning down some money (in the VC case). For employees, it might be scarier, but employees shouldn't be slaves to begin with.
To me, it is one of the feminist headfakes that looking similar is what matters most. Like suppose a girl is interested in maths and another girl is interested in dolls, and a boy is interested in maths and another boy is interested in football. Feminists have us believe that the maths boy and the football boy have more in common than the maths boy and the maths girl. That's just nonsense.
When I was a kid, I liked books with female heroines just fine - there are actually a lot of them because one of the most famous children's books authors was a woman who wrote books like Pippa Longstocking. Now feminists have taught me that I should consider the gender of the heroes, and they ruined the books for me to some degree (especially the new ones that are obviously written especially to appease the feminists, giving girls unrealistic superpowers).
As far as I can see, it is mostly feminists who tell girls that they would have a hard time in tech. I don't want anybody to tell that to my daughter, as I believe it to be very wrong. I want my daughter to be able to learn from everybody, not just from women.
