Earlier quoted context omitted.
I don't think pg would behave like that, let alone say that. He was 29 when he started Viaweb, which is not far from 35. YC has funded people over 35 as well.
I love that I'm being downvoted for quoting pg.
The downvotes were more likely because the comment was false (pg and YC invest in plenty of founders over 35) and unduly personal ("your mindset is exactly why...").
