Don't you think teaching via a chatGPT- like system is a possibility?

I know for certain automated machine maintenance is doable, because it's already being done.

Doctors, ditto - diagnosis via expert systems, physical procedures via the same equipment that we use for remote surgery.

I don't know what "administration" means here, but it's hard to imagine that most of the folks in bureaucracies couldn't be replaced right now, particularly if direct-democratic institutions cone to the fore.

Even caregivers may largely fall by the wayside as robotic and virtual systems and brain-machine interfaces improve.
