Physical AI isn't just humanoids and autonomous vehicles. The real scope: any system with sensors and actuators becomes a candidate. Industrial robotics, logistics automation, precision agriculture, medical devices, smart infrastructure. The pattern: sensor input → AI processing → physical action. We're talking edge compute running vision models on factory floors, reinforcement learning controlling robotic arms, sensor fusion in warehouse systems. Every industry with physical operations is basically an untapped deployment target for embodied intelligence. The constraint isn't the concept, it's the engineering: real-time inference, safety guarantees, domain-specific training data.
