i agree with you entirely, so i wasn't going to "that's obviously because" you, anyway. my own reflection is that when I first got on the internet the intersection of people I knew on the Internet and IRL was an empty set, then for about 10-15 years it was nearly a perfect union, and now it's pretty close to disjoint again.
i don't think LLMs are going to end human-to-human interaction on the Internet, it'll look different, but as long as >1 human values community with only humans, it will find a way.
