The Internet is the world’s largest copy machine. At its most fundamental level this machine copies every action, every character, every thought we make while we ride upon it. In order to send a message from one corner of the Internet to another, the protocols of communication demand that the whole message be copied dozens of times in an ordinary day as the cycle through memory, cache, server, routers, and back. Tech companies make a lot of money selling equipment that facilitates this ceaseless copying. If something can be copied – a song, a movie, a book – and it touches the Internet, it will be copied.
