TikTok just dropped a new realistic beauty filter

dude what if HackerNews had a Graybeard filter so every reply i wrote sounded like i really really knew what i was talking about even if i didn't.

There was a post a few days ago about a GPT that was trained on HN. It would be interesting if it could be tweaked so that highly-upvoted posts had more weight. That would allow you to create output that sounds like a smart HNer.

I wonder what attributes such comments have in common?
