We'd all be a lot safer--even the capital owners--if today's robotics and multimodal intelligence were near the ceiling of what's possible, or even near the bend in the logistic curve where things slow down a lot.

I haven't seen evidence of that. I see evidence of rapid advances in task length, general capabilities, and research and development capabilities in AI, and generality, price, and autonomy in robotics.

How much headroom in these capabilities do you believe we have, before a data center can protect and maintain itself and an on-site power plant? Before robots can run a robot factory?

The real transition would be from human-owned capital to self-owned capital. You are right that current capabilities and autonomy don't allow for that yet.
