Etching a model's weights on silicon is another way to utilize non-top-notch tech-processes, while maintaining or improving performance. (and it suits robotics well)
Putting a model's weights in read-only memory close to the processor is certainly a way to increase token/sec generation speed, but of course does nothing to increase intelligence. Robots aren't going to help though - semiconductor manufacturing is semiconductor manufacturing regardless of whether you are etching GPUs or memory onto your wafers.
Robots don't need that much intelligence. High-speed joint control, "hand-eye coordination", the higher level tasks can be delegated to external models. Distillation already works quite well for isolating the required functionality.
But, the production expansion rate of none of these companies is being limited by lack of trained personnel, and if it were it would surely be faster to hire/train more humans since robots are still very far from human dexterity, not to mention intelligence.
Robots and AI are tools of automation, a way to replace humans with machines, but not all the problems in the world are bottle-necked by lack of humans, or the cost of humans.
