Woz and Jobs didn't invent anything but they were on the bleeding edge of commoditization of computers. The Apple II was one of the first computers available to the general public, which the average person could buy and use. The Commodore PET came out about the same time. There were a couple of CP/M based machines available a few years prior; but, in the 1975 timeframe even a CP/M system tended to be hideously expensive. It was unlikely anyone outside of a serious hobbyist would buy one for personal use. Machines like the Altair 8800 were the smallest and cheapest computers available at the time the Apple II was introduced, and a complete system could easily cost thousands of dollars.
For the sake of full disclosure: I was around to see all of this (as a teenager) and learned on these machines.
I'm within 10 miles of a nuclear power plant with two reactors, a shipyard that builds nuclear powered ships, and a naval base with numerous nuclear reactors floating at the docks. I have not seen any such document for any of my four children. What I have signed is a waiver giving them permission to treat my children medically in an emergency, which is a no brainer. If your district specifically calls out treatment "in the event of a nuclear meltdown" then your school board has issues.
