I think that, ultimately, systems that humans use to interact on the internet will have to ditch anonymity. If people can't cheaply and reliably distinguish human output from LLM output, <i>and people care about only talking to humans</i>, we will need to establish authenticity via other mechanisms. In practice that means PKI or web of trust (or variants/combinations), plus reputation systems.<p>Nobody wants this, because it's a pain, it hurts privacy (or easily can hurt it) and has other social negatives (cliques forming, people being fake to build their reputation, that episode of Black Mirror, etc.). Anonymity is useful like cash is useful. But if someone invents a machine that can print banknotes that fool 80% of people, eventually cash will go out of circulation.<p>I think the big question is: How much do most people actually care about distinguishing real and fake comments? It hurts moderators a lot, but most people (myself included) don't see this pain directly and are highly motivated by convenience.
