The point I was trying to make is that he never once mentioned the word "hacker" in his essay. Didn't try and dive into it's connotations, and implications. Didn't want to even take a paragraph to capture the essence of being a computer hacker.
I'm guessing that it might have been in an earlier draft, when he decided that it was distracting from the actual point he was trying to make, which was relatively straightforward.
Think about it like a funnel
1) Some % of people are women
2) Some % of women are programmers
3) Some % of programmers who are women are hackers
PG posits that the biggest "bounce rate" is woman -> programmer rather than woman programmer -> woman hacker
Empirically, I recall the article claiming around 1/5 founding teams having 1 woman, (notably this is not a % of founders but founding teams).
Anecdotally I claim that the % of women programmers is less than this number.
I could get more and more concrete, but I think you get the idea.
