That works fine for purely text-based or digital knowledge domains. So, sure, many types of programming, probably most game play, certainly all video game play, many types of purely creative fictional writing.
I don't want to downplay those applications, but the killer breakthrough that the breathless world imagines and has wanted since Turing first talked about this is accurately modeling physical reality. "Invent a better engine" and what not. Without being physically embodied and being able to conduct experiments in the real world, you can't bootstrap that, short of simulating physics from first principles, which is not computationally feasible. You're inherently relying on some quorum of training material produced by embodied sources capable of actually doing science to be factually accurate.
Not dissimilar to how large organizations operate today! Humans operate at the edge collecting sensory data (making measurements, inputting forms, etc.) and the "brain" is a giant management and software apparatus in the middle.
