The problem
Physical AI has a data problem, not a model problem.
Language models learned from a written record that took centuries to build. There is no equivalent record of how people actually fold a shirt, guide fabric under a needle or wipe down a car. The movements that make up real work were never written down. They live in people's hands.
So teams improvise, and every shortcut costs them somewhere.
Lab-staged demos
Clean and controlled, which is exactly the problem.
Breaks in the first real kitchen.
Scraped internet video
Plenty of it, but unlabelled, unconsented and shot from the wrong angle.
Fails the first legal review.
Teleoperation
Precise, but slow and expensive to scale beyond a narrow skill.
Months of operator time for hours of data.
The result is a quiet tax on every physical AI team: months spent sourcing, cleaning and clearing data before the first training run, and models that look brilliant in the lab and hesitate everywhere else.
