The one thing LLMs do well is manipulating text. The danger is obviously that it will reduce individual expression and make everything the same mediocre sludge.

For me writing is a way to capture a stream of consciousness so I don’t really see the advantage of using an LLM.

When I see some trivial mediocrity I simply stop reading. It’s just not interesting.

As with most things, it can get interesting if you don't rely on defaults. My personal amusement in that area includes chatting up fictional characters with unique 'voices'. And even simple capture of consciousness can get more interesting if you apply stylometric analysis to it.
