The LLM writing sameness is bad. Use LLMs to help your writing! But don't include a word they generate, even just a vocabulary adjustment, in your own output. Have them critique structure and flow, spot overused words and passive constructions and dumb picks for topic sentences. It's great for that, and those are all objective improvements in your writing that won't mess up your style. The LLM sameness in web design…
I would feel very weird using LLMs for writing, except for filing out stupid applications. I've had collaborators use LLMs for some technical writing and it's pretty much always borderline nonsense that has the aesthetic of something correct. For creative writing, I feel like heavily using an LLM would defeat the purpose :shrug:
