In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1.

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.     ;)

given the way people drive, one can only imagine the carnage if they flew!

I don't want -everyone's- car to be able to fly.  Just mine.     ;D
Of course, that still leaves us with "some idiot with no flying experience"...
