Today we live in a world linked by “cyberspace”, a word created in the 1980s but only ten years in common use. It stands for the completely man-made substrate we all share intimately on our smart phones, tablets and desktops, and that pervades the operations of banks, airlines, electrical grids and even manufacturing plants. It stretches under and into all the relatively instantaneous (and profitable) communication, cooperation and coordination that sustain our modern quality of life. So much modern wealth now relies on cyberspace that, increasingly, groups and nations are beginning to fight in it and over it as well.
