I agree with your vision of endgame. We wouldn't even need a screen, we will communicate verbally or with signs with our agents with some device that will have a long battery life and will always be on.

I just hope that we retain some version of autonomy and privacy because no one wants the tech giants listening in every single word you utter because your agent heard it. No-one wants it but some, not many, care.

Agents deployed locally should be the goal.
