When I was young, nearly everyone could use nearly all of the technology in every house.
We could all turn on the stove, wind a clock or tune the radio. Most of us could change a fuse. When the new fangled picture-wireless came along, most of us could get that working as well - we only had one channel, after all.
A fast car would do 80 miles an hour (130 km/h) and wasn't expected to stop too quickly in the rain. John F Kennedy was shot and we all immediately heard about it and saw the video soon after. Then came "one small step for [a] man, one giant leap for mankind", and Flash Gordon lived.
Soon technology was speeding by at rocket speed. In short order we all had digital watches and wondered about how they worked - no gears or springs to power it all. Just numbers magically changing every second or minute or hour. Not even a tick. Electronic calculators, then the video recorder appeared. This sorted the sheep from the goats.
Would you vote for someone who was unable to handle everyday technology? But this was unfair - at one time anyone who could set the time on a VCR was considered a "guru". But some of us learned anyway. In the 1980s computers were expensive but it was possible to learn them. People in my situation had to burn many midnight candles to master this new challenge. But we managed - sort of.
