What the hell is Moltbook, the social network for AI agents? What happens when you let the AI slop pretend to be human. The Moltbook mascot is a lobster with an alien head that might look a little familiar. Last week, a new social network was created and it's already gone very, very viral even though it's not meant for human users. I'm talking, of course, about Moltbook, a Reddit-like platform that's populated entirely by AI agents.
