Training robots on general internet video data is the key unlock for embodied AI
The major breakthroughs in AI have come from unlocking new data sources. For robotics, teleoperation and sensor data are too small to achieve general intelligence. The key bet is that if a humanoid robot's embodiment is close enough to a human's, it can pre-train on the immense volume of general internet video data of humans — orders of magnitude more than any curated dataset — which is the only path to solving the data scarcity catch-22.
China's world model startup boom is driven by its dominant humanoid robot supply chain and government automation support, creating a structural advantage for physical AI applications.

Cross-embodiment pretraining on internet human video is the critical unlock for general robot intelligence
1X and Agility both identify the data pyramid: teleop data (small, high quality) → human sensor data → egocentric video → general internet video (massive). Only robots mechanically identical to humans (skin, tendons, hand dynamics) can transfer learn from the bottom layer — YouTube-scale data — solving the robot data scarcity bottleneck. This is the 'catch-22' breaker for embodied AGI.

Unlike generic generative AI that learns world dynamics from observation, Dassault's industry world models embed scientific laws (physics, chemistry, material science) and multi-scale simulation solvers, enabling AI that 'understands why' a plane flies rather than just predicting it will.
Real-to-sim-to-real loop with generative physics is the training ground for physical AI
Physical AI requires three pillars: (1) real-to-sim reconstruction of environments, (2) physics-grounded simulation (Isaac Sim) fused with generative video (Cosmos) for infinite scenario generation, and (3) sim-to-real reinforcement learning that respects electromechanical constraints; this closed loop is the 'eval' system for robotics, analogous to LLM benchmarks.
