To make us all aware of the "slave-power" provided us daily, even hourly, by automation and computers, our students should spend time COMPUTING THE SLAVE POWER OF EACH SERVICE PROVIDED US.For example, when I was young, telephonic communication depended entirely on humans putting plugs into "telephone boards" -- as with Lily Tomlin's friend Ernestine ("One ringy dingy. Two ringy dingy.") Nearly all of that is automated today. It's been estimated that going back to plugboard-cum-human -- with present demands on the telephone system -- would require most of the entire AMERICAN WORKFORCE, if not all of it!
To enforce that, you would have to impose SLAVERY. What is the slave-power involved in achieving one minute of telephonic comunication?
Electricity is measured by the supplying company in killowatt-hours. What is the slavepower-hour for operating a TV set? a computer? a toaster? Etsettery.
Incidentally, the term "computing machine" is nonsense. Most "work" of computers is not COMPUTING. And it is PHYSICALLY NOT A MACHINE.A MACHINE OPERATES UNDER THE TRANSFORMATION RULE KNOWN AS GALILEAN, A RULE WHICH EVERY ELECTRONIC DEVICE VIOLATES, OBEYING RATHER THE LORENTZ TRANSFORMATION RULE. So, I speak of a "computer" as an "electrine".
Another term used herein is one I learned from webiacs: "bot", for "robot".
