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.
I think you'd find that, in a lot of contexts, a lot of humans care more about reading quality content than concerning themselves with who wrote that content, which is effecively "siding with ChatGPT" here, I guess.
