It may no longer be possible to live your life without dependence on the Internet. Unlike television, you cannot entirely unplug from the Internet even if you want to. If you are dependent on those who are dependent on television, then so what? If, however, you are dependent on those who are dependent on the Internet, then so are you.

The source of risk is dependence, and security is the absence of unmitigatable surprise. It is thus obvious that increasing dependence means ever more difficulty in crafting mitigations, and that increasing complexity embeds dependencies in ways such that while surprises may grow less frequent, they will be all the more unexpected when they do come.
