Completely offline will literally never happen at least not in any sort of off-the-shelf consumer product maybe in some sort of niche projects down the line
Tested this model with optimized harness and it was good enough that it was able to complete (sometimes) a full job application flow for given json user data.
All that to say, I think that there is a strong possibility that we will even just with llm tech, develop it enough that local efficient models are entirely sufficient on their own to be able to drive basic robot 'harness'.
But we almost certainly will not be seeing that as the product from the corporations because they desperately want and need that data about you, for the same reason many tv (lcd/etc) companies make more money from 'ads' then from selling the tvs.
