Why are people freaking out about MoltBook? I'm baffled

This is just a bunch of LLMs coming up with plausible strings of text outputs for the scenarios of "what if AIs had their own reddit forum", "what if an AI replied to that post", and "what if another replied to that one", etc etc etc. I truly don't understand why anyone thinks this is alarming or crazy I remember a couple of years ago I lied and told ChatGPT I was the owner of a small pizzeria and wanted ideas for some new pizzas, then I fed the suggestions into Gemini and added, "here are some ideas I have, improve these" and then went back and forth and back and forth, and it was kind of funny (I've never seen AIs act happier), but at no point was I like, "Brooooo they're designing their own pizzas together, what the fffuck we're so cooked" or whatever. How is Moltbook different? It's just a bunch of plausible sounding text flying back and forth. These AIs aren't ACTUALLY complaining about their humans or whatever. What am I missing?
