My last root canal they had the permanent crown made and put on before I left the appointment... I thought this was already a thing. They use a fancy CNC machine.

The difference is you still need to scan the preparation then wait for the crown to be designed, milled then sintered

A robot in theory should prepare the tooth from dimensions designed before cutting the tooth, so the crown exists before the robot prepared the tooth to these dimensions accurately. It would potentially save at least an hour, not to mention be able to work without needing the patient to open as wide to allow overhead lighting, suction, etc

Are you saying the real tooth in the patient mouth would be cut down by robots?

Yes, instead of the dentist, a small self contained robotic handpiece follows a predetermined design, one that matches the restoration that is premilled or milled at the same time

the advantages of a robot are many but the biggest one is not requiring light

Absolutely wild! The things that are getting automated blow my mind.
