When Videos Grow Hands: How PhysWorld Teaches Robots to Stop Hallucinating Physics
Why This Matters Now The robotics world has spent years fantasizing about a shortcut: take a generative video model, tell it “pour the tomatoes into the plate,” and somehow—magically—the robot just… does it. But there’s a quiet problem no one likes to admit. Videos are visually plausible, not physically correct. A model can show a tomato pour; it cannot guarantee the tomato isn’t clipping through the pan in frame six. ...
