That wasn’t so much a “fact” told in school as it was a prediction, and it was true for them. Some people carried pocket calculators, but most people didn’t. Some supermarkets has calculators built into their carts, but most didn’t.

Tiny photocell powered calculators used to be everywhere. There were “thin” ones to fit in your Costanza sized wallet, Mousepads with them built in, and my wristwatch in 6th grade had one with tiny rubber keys.
