Technology

I could however totally see an economy where the chips themselves while cheap to produce cost a premium based on model and number of parameters.

Because the tech is certainly impressive and they have proof of concept. I don't know how scalable this is for them (or others), but it clearly works and shows immediate advantages. If it could integrate with existing consumer hardware, like say a PCI card you plug the chip into and switch them out when you want to change the model, anybody could easily have this at home.

But with capitalism we'd probably have to settle for DRM'd chips that self-destruct after X many tokens generated lol.
