First I heard of these exascale computers was when a Chinese group published[1] a pre-print in which they classically replicated the Google quantum supremacy result in about 300s. The Google team estimated that a supercomputer (Summit) would take 10e3 years to do the task, which apparently really got to the classical HPC community.
