This hit close to home. I don't think it's exclusive to programmers. I think this is happening in all industries, we just see it to a greater degree. Everyone's aware of polarization in politics, but I think it's happening to race, gender, and any other culturally distinct segment of humanity. With all this increased connectedness, we're distilling into groups that are like-minded, politically and otherwise.
I went to an all boys school. I believe it was terrible for social development and made it hard to relate to women. When I see that same-sex education is on the rise I feel we're making a big mistake.
