If it becomes one, then that will be the end of sites like Hacker News.

This site, at its core, is fundamentally too low-bandwidth, too text-only, and too hands-off-moderated to be able to shoulder the burden of distinguishing real human-sourced dialog from text generated by machines that are optimized to generate dialog that looks human-sourced. Expect the consequence to be that the experience you are having right now will drastically shift.

My personal guess: sites like this will slop up and human beings will ship out, going to sites where they have some mechanism for trust establishment, even if that mechanism is as simple and lo-fi as "The only people who can connect to this site are ones the admin, who is Steve and we all know Steve, personally set up an account for." This has, of course, sacrificed anonymity. But I fundamentally don't see an attestation-of-humanity model that doesn't sacrifice anonymity at some layer; the whole point of anonymity on the Internet was that nobody knew you were a dog (or, in this case, a lobster), and if we now care deeply about a commenter's nephropid (or canid) qualities, we'll probably have to sacrifice that feature.

I'd rather keep the feature, pesonally.
