> If they can't, then is it really quantum supremacy? Yes, quantum supremacy on an artificial problem is quantum supremacy (even if it's "this quantum computer can simulate itself faster than a classical computer"). Quantum supremacy on problems that are easy to verify would of course be nicer, but unfortunately not all problems happen to have an easy verification.
