The author of "The Other Money Problem," seems to assume readers are not aware of change or that Paul Graham can't continue to be honest and interesting now simply because he makes more money than he did previously. According to this theory, J.K. Rowling would be less interesting to read now that she's rich, but I would argue that her new work is better. Dave Chappelle, Chris Rock, same thing.
Each of Paul Graham's essays were written as he slowly evolved into the man he is today. He was changing the entire time. Also, he knows more now than he did before.
The thing that saddens me is not Paul Graham getting advice from friends, it's people who try to take some of the shine off.
