Not only that, but even humans with our actual GI, can only come up with theories and hypotheses that may or may not reflect reality. This is why scientists have to do experiments, to establish empirical evidence that they are right (or possibly more often, that they are not right).

There's also the fact that there's no known upper limit on the complexity/time needed to solve an arbitrary problem. Just because you can create an AGI doesn't mean nearly impossible problems suddenly become tractable.

Humans can already create humans that can outsmart them, and only every so often do they solve an interesting problem here or there.
