I've been talking to Opus a lot lately though, and this could almost be something it wrote; it also has the tendency to write AI-ish looking blurbs that are missing the information-free pitter-patter that bloats older and lesser LLMs. People are going to hate me for saying it but sometimes it words things in a way that are actually a joy to read, which is not an experience I've had with other models. Which is to say, maybe what we hate about AI has less to do with the visual patterns and more to do with what we expect them to mean about the content.
But I think there will always be that feeling of: a human being took the effort to write this. No matter how informative or well written an AI article or comment is, it isn't something we instinctively want to respond to, the way we do when we know there is a person behind the words.
