I have a genuine question for you here dang. In another comment in this thread [1], the poster admitted that he did indeed generate (or at least rephrase) his comment with AI. I didn't find this surprising, and at least a few other people apparently didn't either. For "uncanny valley" reasons that are difficult to put my finger on, the wording of the comment just jumped out to me as LLM generated.
So the user "searealist" who you're responding to was correct in saying the comment was written by AI. Are we not supposed to call that out when we notice it? It's difficult because it's typically impossible to prove, and most people won't be as honest as the OP was here.
If what "searealist" did here is not acceptable even though he was right, what are we supposed to do? Flag, downvote?
Personally, I do not want to see any LLM generated content in HN comments, unless it's explicitly identified by the person posting it as a relevant part of some conversation about LLMs themselves.
