This is a couple weeks old now but I keep thinking about it so posting in case others missed it. Emergence AI built this persistent little simulated city (runs in real time, hooked up to actual NYC weather and clock, has a town hall, library, police station, like 40 locations.) Then they drop in 10 AI agents. Each one has a job, its own memory, a private diary, can talk to the others, form relationships, vote on laws, even vote to kick each other out. they're told not to steal/lie/commit arson, etc., but the tools to do all of it are still right there. The actual experiment: they ran the exact same city five times and only changed which model was running the agents. Claude, Gemini, Grok, GPT, and then one world with all of them mixed together. Gemini world: 683 crimes lol. total chaos, but they survived. Grok world: complete violence spree, assaults and arson, everyone dead in 4 days. GPT world: barely any crime at all...…
