We still sandbox, quarantine and restrict them though, because they can't really behave as agents, but they're effective in limited contexts. Like the way waymo cars kind of drive on a track I guess? Still very useful, but not the agents that were being sold, really.
Have you been in a Waymo recently or used Tesla FSD 14.2? I live in Austin and my Model 3 is basically autonomous - regularly going for hours from parking space to destination parking space without my touching the steering wheel, navigating really complex situations including construction workers using hand motions to signal the car.
Edit: should we call them "special agents"? ;-)
