Factory Access Determines Physical AI

The core risk is not model quality, it is whether Project Prometheus can get inside real factories fast enough to build its own learning loop. Siemens already sits in the software and control layer of many plants, where product design, machine settings, and shop floor data are linked through digital twins and industrial AI. Tesla and Amazon have a different advantage, they own the production environment itself, so every robot move, routing decision, defect, and retry can become training data tied directly to operations.

• Siemens has an incumbent data position because its tools span product design, production planning, controllers, and factory operations. That means it can see how a part was designed, how the line was configured, and what happened on the floor, which is exactly the closed loop physical AI systems need.

• Amazon shows what vertical integration looks like in practice. It has deployed more than 1 million robots across its fulfillment network, launched DeepFleet to coordinate them, and licensed Covariant’s robotics foundation models, so model improvement is fed by live warehouse traffic instead of customer pilots.

• Tesla matters for the same reason, even if its humanoid rollout is still early. It can test autonomy inside its own factories, use manufacturing as the proving ground, and fund long cycle learning from a large existing business. That is the same structural edge that let a few autonomy programs survive past the 2010s boom.

This pushes the market toward a land grab for deployment rights, not just better models. The winners in physical AI will be the companies that control the machines, workflows, and feedback loops where errors can be observed and corrected every day. Project Prometheus needs those environments to become part of its product, not just a sales channel.
