I'm not seeing any top comments talking about GPT-3 or anything that he talks about
The user in question made ~16 replies, 4 of them top level, and the majority of them (including some top level ones) one word or one sentence (and generally disparaging). When someone that has enough points here to indicate they've assimilated at least somewhat posts "lol" and "there is no spoon" as top level comments in addition to other ones and other disrespectful comments, my guess is there's something else going on and this is just an outlet for it. In that respect, I don't think it's indicative of HN, as I think it could have happened anywhere.
It's like they sold their account or got hacked or forgot what website they were on/which one their troll account was.

It is somewhat ironic that HN comes across as uncivil compared to the typical free-for-all in the MR comments.
The author wishes us to know they're happier about compliments on MR than the user on HN who obsessed about the article being written by a bot to the point of derangement (and perhaps more hurtfully, someone else who said "I don't think so" then edited the comment after reading more articles to say they'd changed their mind, but probably there was a human in the loop somewhere!)
GPT-3 wouldn't come up with the perfect clickbait title to post about being offended, so probably human :)
