Agreed, I think if you showed me as a kid that a tiny microSD could store every game I ever played and still have room for every TV show I ever watched without getting remotely full, and was affordable, it'd be impressive. But it wouldn't blow my mind as something inconceivable, I had already known floppy disks both shrunk in size and increased in capacity.

Plus, I'd imagine "the ENIAC guys" would quickly realize all the things that were computationally infeasible in their time had more or less been done along the way to modern computers.
