I'm surprised that someone would came to the rescue of bullet points for the sake of defending quality writing as they seem to me exactly the opposite of quality writing, but I guess this could be a matter of taste

I agree. I've been annoyed by bullet points (exceptions: instruction manuals and lists of ingredients in recipes) starting well before AIs started writing text.

Thankfully, so far the LLMs in my life will avoid bullet points if I ask them to.
