It is not AI generated and unlurker just finds articles with active conversations, it doesn't do any kind of comment automation. Upon reading it again, my comment in question maybe didn't add all that much; I just found the article interesting, so maybe I get where you are coming from.
As I mentioned in another reply, the weirdest thing about this comment chain is I saw this article on the front page, not unlurker (there wasn't much conversation yet when I posted so it would not have shown on the unlurker view I use).
Is "the author" a phrase AI prefers? Maybe I'll need to retire that along with "delve" and the em-dash and "you're absolutely right".
