That is quite a comparison Warren.
Additionally, one of the very first digital computers was the ENIAC.
18,000 valves, 1800 sq feet and weighed 50 tons. (some sources state 30 tons) 160kw of power to drive it.
Its internal memory was only 20 words at first. This was upgraded through time. (1946)
Various methods to determine the best materials to build the computer were employed.
Lab rats were starved in an experiment to find what wiring insulation they would attack first. I'd expect our flash drives are quite safe.
Now we carry items that far exceed the capacity of old systems in our pockets. Thanks Warren, its quite an eyeopener, bigger is not better
Cheers
