Binary logic and binary math allowed the digital revolution. It didn't have to be this way. There are still analog computers and computers could make decisions between three choices at a time instead of two, but it seems uneconomic right now. A/D and D/A (Analog to digital and vice-versa) is convenient enough and quick enough that we have learned to ignore the difference between the two kinds of data. This pattern of yes-no choices (bits) has not made our world black and white. As choices have broken down and simplified, patterns have compensated by finding new intricacies.
