Earlier quoted context omitted.
A very smart man, PG himself, once said [0]: > I actually worry a lot that as I get "popular" I'll be able to get away with saying stupider stuff than I would have dared say before. PG started writing essays about what he knows well (programming, start ups), then about things he knows a bit (painting) and then stuff like this, or his essays on economic policy. In any case, he predicted his own future quite well. [0]…
Popularity and power seem to do that to people quite often, don't say? Which is said, especially in PG's case, because I like his older essays a lot. The now ones, well, not so much.
As you get richer and more famous, it becomes harder and harder to find an editor/friend you will trust to tell you you're being stupid. You can use the internet at large (that's always full of people to tell you you're stupid) but it can be quite hard to filter.
