In a previous life, when I was a little less mature of a geek than I am now, I worked as a security guard in a place that had a pair of Cray ! supercomputers and I would often chat with the folks who operated the computer center and with some of the folks "upstairs" who programmed those monsters and I was suitably impressed with both the capabilities (as much as I could glimpse of that) and with the enormous infrastructure required to run them.
In those days, I was required to turn off my Motorola HT90 hand-held radio when I passed through the computer center lest the radio signal scramble a bit here or a bit there.
Today, my hundred dollar Motorola "Moto G Power 5G" smartphone from Walmart apparently has more processing power than the pair of Crays - but it also does extra duty as an alarm clock so I casually toss it across the room onto my pillow before climbing into the sack.
Progress marches on, but my car -still- does not fly.
