Not to be too too contrarian, but the idea is actually being used all
the time. It really starts with two voltages that we can interpret as
booleans to implement boolean logical formulas and then, whaddayaknow,
you can implement arithmetic using boolean formulas by treating the
binary digits of a number as truth values....

But of course, this is only something you think of when you peel back
a layer of abstraction.

THAT is the real sin, here. :)
