It's not satire, but it is a schtick. If you listen to an interview w/ the guy, he's not at all what I expected from the book (and I had the same response as your wife, though I've heard worse in SV many many times and sort of just appreciated the honesty even if it doesn't reflect my worldview). So does it still reflect a culture that's been problematic in SV that we want to get rid of? For sure, yes. But also, maybe people should be allowed to make mistakes - this kind of sexism was widely tolerated in SV even five years ago. That doesn't excuse it, but I sort of think we have to allow people to grow and change.

People should be allowed to make mistakes. If they change. It is clear that he is still proud of this writing. This isn't "wow, in my younger years I was really awful and I feel bad and have changed".
