This comment makes two interesting assumptions:

1) That the entering of LLMs onto the scene of communication implies that real human beings need to change their style as a result.

2) That nobody can make an LLM talk like Cleetus McFarland.

To me, "I know that text is AI-generated" accusation smacks of the "We can always tell" discourse in the transphobia space. It's untrue, distasteful, and rude.

"just develop a personality" sounds like a shallow dismissal. Most comments in most threads could theoretically be autogenerated when given style samples of what fits on HN and what opinion to use

A personality hardly shows through in a handful of sentences, besides which, I'd rather judge comments by merit than by the personality of the poster (hacker ethics, point number 4: https://en.wikipedia.org/wiki/Hacker_ethic#The_hacker_ethics)
