Apparently they can't, right now, as you admit. Anyway this is turning into a stupid semantic argument, have a nice day.

  If they can't, then is it really quantum supremacy? They claimed it last time in 2019 with Sycamore, which could perform in 200 seconds a calculation that Google claimed would take a classical supercomputer 10,000 years. That was debunked when a team of scientists replicated the same thing on an ordinary computer in 15 hours with a large number of GPUs. Scott Aaronson said that on a supercomputer, the same technique would have solved the problem in seconds.[1] So if they now come up with another problem which they say cannot even be verified by a classical computer and uses it to claim quantum advantage, then it is right to be suspicious of that claim. 1. https://www.science.org/content/article/ordinary-computers-can-beat-google-s-quantum-computer-after-all https://www.science.org/content/article/ordinary-computers-c...

    > 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.
