Parents complaint is explicitly not about the style of the prose, use whatever you want to check your grammar and reduce redundancy. The complaint of poisoning the well is regarding content that is not intended to express anything at all, the old “why would I read what nobody bothered to write”
The issue is that you're conflating the process of transcription with the act of expression. If I feed an LLM my own raw research notes and technical observations and use it to help structure those thoughts into a readable essay, I haven't "avoided writing".
The "why would I read what nobody bothered to write" argument only applies to people who ask a bot to hallucinate an opinion from scratch. It doesn't apply to authors using the tool to clarify their own ideas.
