thanks for checking my calculations!

unlike the other examples, the category of 'supercomputer' has shifted over time. initially, i was thinking of a cray-1, which is the machine that popularized the term 'supercomputer' https://books.google.com/ngrams/graph?content=supercomputer&.... it was only about 160 megaflops, which is ten million times 960 calculations per minute. that wouldn't normally be described as 'dozens'; it's about an order of magnitude high. so i should have done my calculations a bit more carefully

up to the late 90s, when the term 'supercomputer' had largely fallen out of use, top-end supers were still in the low-digit gigaflops: https://www.hpcwire.com/1997/04/04/tera-mta-computer-posts-b...

you are of course correct that current machines are many orders of magnitude faster than that, and even a single video card is about three orders of magnitude faster
