The physical AI field treats sim-to-real gap, generalization failure, and data scarcity as separate challenges requiring distinct solutions. We demonstrate these are symptoms of a single root cause: limited physical and disturbance real-time parameter estimation scope (classical estimation constraint: N independent unknowns require N independent measurements). Current physical AI approaches (domain randomization, continuous learning, foundation models) attempt to pre-train reactions for all potential conditions, which is fundamentally impossible for systems that are rich in independent time-varying parameters relative to independent sensed outputs. We present a technology that performs essentially unlimited parameter estimation based on sparse basic system output sensing to enable physical AI deployments to autonomically and continuously comprehend and adapt to the stochastic real world. We also discuss implications for accelerated and sustained GPU demand (training + inference) at category scale, analogous to what LLMs achieved for software AI, across billions of time-varying systems in 25+ application categories spanning industrial equipment, robotics, aerospace, healthcare, and infrastructure systems.
