> I believe the issue of proving who is and who isn't really human on the Internet will be a really important issue in the coming years

On a site like HN it's kinda easy to vet for at least those that already had thousands of karma before ChatGPT had its breakthrough moment a few years ago.

Now an AI could be asked to "Use my HN account and only write in my style" and probably fool people but I take it old-timers (HN account wise) wouldn't, for the most part, bother doing something that low. Especially not if the community says it's against the guidelines.
