I'm not saying that PG is necessarily sexist or a bad person for saying all of this. But he did basically say that there aren't a lot of twenty-something females who have been hacking for 10+ years. And then he seems to sort of back away from that statement in "What I Didn't Say". In the original interview, he said "We can't make [these] women look at the world through hacker eyes and start Facebook because they haven't been hacking for the past 10 years." In "What I Didn't Say" he says "When I saw [the above quote] myself I wasn't sure what I was even supposed to be saying. That women aren't hackers? That they can't be taught to be hackers? Either one seems ridiculous." Basically, he was saying a less-crazy version of the first statement. Namely, that there aren't that many 20-something female hackers.
In summary, it seems like PG stated an inconvenient and perhaps unfortunate truth (and implicitly declined to get into what he could perhaps do to make this truth untrue), The Information reported it in a responsible way, and then ValleyWag re-reported it in a misleading and sensationalistic way. And then PG somewhat disingenuously claimed that he didn't say what he actually said.
Also, the irony is rich that all of this involves the guy that wrote "What You Can't Say".
The bigger problem with pg's statement is not the 13 year old girl claim. It's that he fully blames them and middle school curriculum while giving YC, PyCon and the startup industry a pass. His stance is we already have an open door and are self-selected, so the problem must be up the line.
You're right, he dodged the question of whether we need to be more proactive, not just open.
So perhaps our industry could make a greater effort to spotlight and support our very best examples of female hackers, and put them in closer touch with 13 year old girls. And to dial down the bro-iness of events and startup office cultures.
Those are examples of being proactive that have nothing to do with lowering standards. Pointing fingers elsewhere in the system is not that different from defending the status quo, because it's an interdependent system.
I also want to point out on the lowering standards front, I'm a female hacker who's been coding since age 6, and I was rejected from YC. I'm actually proud of that fact in the light of this discussion. I'd hate the whole foundation of my startup to be the source of such rabid debate, and for folks to think I just got in because I'm a unicorn and we need more unicorns in tech.
Are those boys to blame for their decision? If not, why are you campaigning to only push money in the direction of girls?
And I'm not campaigning to push money in any direction. That's a separate issue.
I agree that it's not obviously a bad thing if all these people who didn't become hackers (female or male) became something else that is socially valuable and makes them happy. But I'm also willing to consider the possibility that some women would have been happier and contributed more to society if they had become hackers, but didn't because they felt out of place or unwelcome when they tried to. And that if that's the case, then I'm at least willing to consider that maybe we as a society should do something about it.
He did only refer to programmers. That's true.
But what he left out is that, he defined programmers as the "pool of potential startup founders". (You have to read the full transcript to notice that.)
So he is not actually referring to a subset of women. He very clearly says women as a whole are underrepresented as founders because they haven't been hacking since age 13 like the attendees of PyCon and open source committers, because it's really hard to get 13 year old girls interested in hacking.
It's completely clear when you read the transcript.
