The possibility of well-written AI prose is a big reason why I dislike AI text generation. Writing for an audience refines the ideas being communicated. If the author doesn't do that refinement themselves, then I'm not reading what the author is thinking, I'm reading what the LLM could patch together from their ideas. If I want the LLM's opinion on how to make a concept work, I can ask it directly. If I'm reading something by an author, I want to know what the author is actually thinking!
