This looks like a good time to point out that equivalent-time and random
sampling oscilloscopes display waveforms having bandwidths in the tens
of GHz which were captured by sampling at rates from a hundred kHz to a
few MHz, and have done so for decades.
For random sampling of periodic signals the resolution is about the aperture,
not the rate.
