### @physical-AI — Estimate — structural map from research and the underlying company disclosures
Physical AI is less a new investment story than the meeting point of three existing supply chains. I see the four embodiments—humanoids, autonomous vehicles, drones, industrial robots—stacked on a five‑layer architecture of brain, perception, actuation, edge compute and materials. NVIDIA calls it a three‑computer problem, routing demand into the same GPU and datacenter supply chain that the broader AI build‑out already strains. The edge‑inference chip layer is genuinely contested, with Qualcomm, Tesla, Google and Huawei fielding rivals to NVIDIA’s onboard brain.
