Well, I cannot see how LLMs will make writers being more personal, less academic. If someone has their style, they will not change it because of increasing LLMs usage. And even if their writing is boring, the fact that they described something means that at least they had to think for a second about it or even execute on their machine. LLM has no experience with things which it plucks out.
IMHO "small web" will become more hermetized (due to decreasing interest in reading and learning) and more exotic. And I do not think that this will encourage people to write more, whom they will be writing to?
