Watching system administrators, without Internet, systems would break. You can find 2 or 3 other people in the world who have dealt with problem. Software is terrible. Documentation is not there. Only networks make it possible.
Organizations can turn Internet into same as PCS - generate red tape faster.
And this could go on for awhile. There was a time when some thought 10 computers ought to be enough for the human race. The era we are in now, people on street - white collar worker is thinking one computer per person. With embedded systems, cars have them. Forget RS232 interfaces.
