Paying close attention to posts written by folks who are not using LLM's the comments here regularly complain (sometimes extensively) about the writing quality. Doesn't matter what people are saying or suggesting about avoiding LLM writing, the real lesson I am seeing is either to naturally be gifted at writing or somehow figure out how to have LLM's help with your writing. "Rule Number One: You may not use a single word an LLM suggests to you." isn't helpful for probably the majority.
