Experience Is Expensive
Captions available
The idea
The physical world does not label itself — a fall teaches at the price of a fall, and a grasp's correctness is not written next to the grasp.
In practice
Language models feasted on self-labeling text; motion generates no feast, and worlds wear out robots and dinnerware.
Where people slip
Expensive experience is the structural gap between talking machines and walking ones — not a temporary lag.
