I don't think it's biased toward men inherintly. It's what I love about programming, the absolute simplicity of binary, the beauty of the baud. Ones and zeros can't be evil :) But I think people are much better at thinking of scenarios relevant to them, so the products tech companies make tend to have a bias toward men. It wasn't built to be that way, we used to have 30% women, hell the first programmer was a woman. But today those numbers are a lot worse, and I don't want that bias to cement. If we get enough representation for women and minorities soon we can avoid creating a more permanent heirarchy.

It's interesting you mention why your wife left. Tech has a bit of an image problem in that regard. I've done lots of work with young girls and the idea that tech is a selfish profession is probably one of the top reasons they avoid it. Of course that becomes circular, the more people who see tech as selfish, the more it attracts money grubbing brogrammers, who then perpetuate that idea. It's one of the many things we need to change if we want to close the gender gap.
