zero and one, on and off

I sense there is a tremendous secret right under our noses, too simple, too close to existence itself to identify clearly. Computers set the world on fire, and their simple secret is the concept of on and off. It is hard to realize that these two concepts, one on and the other off, could be so simple as they are. But they are a part of a mind boggling advance, awakening and even changing our thinking in a new way we have yet to fully appreciate. Always look to the simple for the complex and start dividing.
