Digital rocked my world. It was 1985, and I was finishing high school. My parents got me a gift, a Texas Instruments TI-1100 II portable digital display calculator—and it was amazing. But this new technology was dangerous; I was curtly reminded by my mathematics teacher that my new calculator was not welcome in her class. (That's right, Gen-Yers; we had to write our equations out in full, in Cuneiform on clay bricks.)
Digital is rocking the world still today, but in even more profound ways. UPS delivered a package recently and I got a "Your package has been delivered" e-mail even before the guy returned to his truck. Meanwhile, in South Korea, commuters waiting for a train wave their smart devices at supermarket billboards, and have the groceries they've picked out delivered to their homes. That's impressive.
