ULTIMATE VULNERABILITY. “Someday the Net will be the summation of the world’s total computing resources. All computers will link up into a chaotic digital soup in which everything is connected – indirectly or directly – to everything else. This coming Net of distributed resources will be tremendously powerful, and tremendously hard to harness because of its decentralized nature. It will be an ecology of computing machines, and managing it will require an ecological approach.”
