True, but as someone who works on quantum physics using classical computers and loves to see classical computers simulating increasingly hard quantum problems, these "crushings" were still only done on classical computers in a way that would scale exponentially with the number of qubits.
Even then, I believe the classical simulations to beat google's 53 qubit device were never actually performed -- it was shown that they could be performed quickly with petascale memory but actually doing it would be a huge expense. Add a dozen more qubits and even the hypothetical classical challengers fall off quickly...
