Rare earth magnets, not chips, are the chokepoint of physical AI, and their supply chain runs through China. Every robot, drone and EV motor needs NdFeB magnets; China controls over 90% of refined supply and about 92% of separated NdPr, and nearly monopolizes the heavy rare earths that let magnets survive motor heat.
