AI-generated writing does not bother me, unless it is intended as prose writing, where the flow communicates as much as the specific facts that are described. For technical writing, I usually just scan for important information anyway, and in that sense the only thing that bothers me about AI-generated writing is if it's too verbose and obscures the important information by leaning ineffectively on jargon and high-minded verbiage. I find that Claude Opus is very guilty of this, whereas GPT 5.6 variants are not.
