I think a similar thing can be said about time. There were a lot of novel things to share in the early days, but these days it seems like his essays have taken a turn toward trite elitism. To be clear, I don't think this is specific to PG, but rather the case whenever someone feels the urge to continue producing for the sake of producing, nor am I saying that I'd be able to do any better. PG obviously has orders of magnitude more wisdom to share than me or most other people.
