The strangest thing about the hack, though, is that social coordination seems to have emerged despite the fact that almost all recent agentic frameworks are pathologically fixated on conversation as a series of "user-assistant" turns. In many cases the data model doesn't even allow for multi-participant discussions at all; you have to RP prompt the model with something like "you are a participant in a discussion with multiple agents, here's the conversation so far, what would you say next" or an even more awkward work-around, such as having other agents represented as tools, or giving up and ignoring them completely. It's a real gap in the current paradigm that wasn't there before ChatGPT (I should know; I fine-tuned and ran literally dozens of multi-participant conversational bots on r/SubSimGPT2Interactive). So it's kind of hard to believe that multi-participant conversation behavior (let alone social coordination) just emerged spontaneously, without deliberate prompting for it or use of a different kind of chat template than ordinary LLM users are given.
