NXP CEO Rafael Sotomayor argues that physical AI should be built around a "neural axis" architecture: low-latency reasoning, coordination, and reflex layers distributed across the edge rather than concentrated in a bigger central brain. He uses drones, software-defined vehicles, and humanoids to show why speed, power efficiency, and local control are necessary for trust and safety in real-world robots.

Rafael Sotomayor’s core thesis is that physical AI will not scale by simply making models bigger; it will scale by placing intelligence at the right place in the system. He frames that architecture as a "neural axis" with three layers of intelligence — reasoning, coordination, and reflection — that are independent but tightly coordinated. In his view, this is the blueprint for trustworthy physical AI because real-world machines need ultra-low latency, distributed control, and extreme energy efficiency to operate safely under physical constraints. He walks through three examples to make the framework concrete. In drones, the reasoning layer handles flight planning and path optimization, the coordination layer manages flight balance and performance, and the reflex layer drives the motor controls and actuation at the edge. …
Near term, the actionable angle is NXP’s positioning around COMPUTEX physical-AI demos and partner ecosystem messaging; the risk is that the story is compelling but still largely conceptual until design wins and product traction are clearer.
Over the next few quarters, the setup improves if edge-native robotics and automotive deployments keep expanding and NXP can convert its architecture narrative into recurring wins in safety-critical systems. If cloud-centric AI stays sufficient for more use cases, the edge thesis will matter less.
The structural thesis is that embodied AI will need distributed, secure, low-latency edge intelligence, which would favor companies that control the system architecture rather than just the model layer. That would make hardware security and control compute a durable strategic layer in AI.
