> If you went back a few decades and suggested people would be strapping supercomputers on their wrists

Smart watches are pretty powerful these days, but you'd have to go pretty far back to find a supercomputer with comparable performance



You know there are people still alive who were mature age adults in 1975?

Thr Cray-1 had 8.39 megabytes of RAM and 303 megabytes of storage.


You can add another decade and a half onto that. 1991's Cray C90 peaked at 8 gigaflops, which is in the ballpark of an Apple Watch (series 5).


3-4 decades seems about right for "a few decades".
