We're not talking about world models enough. We're obsessed LLMs, but LLMs understand text, not reality. They are map-readers, not explorers. A robot arm doesn't have to break 1,000 actual cups to learn how to hold one. It simulates the grip, detects the slip, and adjusts its force in its internal world model first. It learns in milliseconds, safely. We don't just ask an AI to hypothesize based on what its been trained on; we use a world model to simulate how a theoretical drug molecule binds to a virus, accelerating discovery from years to minutes. This video is some clips of my favorite worlds I've been making in World Labs , who just opened up their private beta to the public this week. In the private beta, I spent hours spinning up worlds either from prompts or via uploading images (like this one of Roble gym @ Stanford). Some of the worlds here are public creations from other users, since you can post your worlds to a feed for others to explore in (it's a pretty fun social product, walking through worlds from other ppl's imaginations).
