Or there's more to learn now and all the "easy" PhD subjects are already taken?

Yeah that could be it. (I'm idly speculating without any knowledge or research. It's just unlike a lot of people here I admit it)

Maybe there's some ideal ratio between "current novelty levels" and "number of PhD candidates".
