A wave of AI world models landed this week, all chasing the same dream: press a key and a neural network invents a playable game world from scratch. We dig into two papers from the same lab that bet opposite ways -- one that heroically fakes a persistent world, and one that refuses to, keeps an ordinary game engine running the rules, and only lets the AI repaint the picture. The humble one wins, and the reason why is a single idea that will inoculate you against world-model hype for a long time. Plus the headlines: the White House's unproven distillation accusation, a real AI-assisted math counterexample humans actually checked, and a phone-sized model with a TLS footgun.
