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.
doesn't mean that the answer is comprehensible or correctly
personally I develop a fatigue reading chatgpt answers, there's some fluff I have problems parsing, I don't know how to describe it.
