This debate reminds me a lot of early-Quora moderation discussions over anonymous users. People wanted to mass-ban any answers from "anonymous" because they weren't from "real people". I argued that, in a public forum, questions/answers should be judged on their content, rather than "who" wrote them. People disagreed. Anonymous functionality on Quora has since been gutted.
AI-generated content seems similar. If a comment is good, who cares whether it was written by Alice, Bob, or an AI? ChatGPT has already proven it can write better answers to some queries than most humans do; I'd rather read the better-quality answer, no matter who wrote it. I'm on HN for the comments, not the people.
