Computers need not just automate what is already being done, but can do completely new things. In the 1970s a new form of cryptography was invented, which is usually presented as an esoteric application of number theory. This new cryptography is asymmetric, meaning that the coding and decoding methods are different. In fact, the basic ideas are easily explained using geometric arguments, and the amazing new applications of asymmetric methods - such as digital cash - become easy to understand.
