Paul Graham was at his best when he gave clear, experience-driven, action-oriented advice. But even then, his advice was flawed... advising people to do things like to discriminate against women and parents.

As he got a little older, he cut back on that pro-discrimination advice... that typical thing where he was able to recognize the problems with his bigotry only after he would have been on the other side of it.

As he has become ludicrously wealthy he has, unfortunately, lost all track of reality. He no longer engages with the practical or the real... instead he deliberately misreads a quote so that he can wrote a pathetic and defensive response to it that engages in bad faith. And because he is ludicrously wealthy, he is surrounded by a mix of yes-men, and other hyper-wealthy sociopaths. So none of them give him critical feedback.

Paul Graham has become useless to society. He is, fundamentally, just a mindless pile of cash.
