When you could discern a real threat from everything else, it was called caution. When you couldn't, it was called paranoia. . . . You cannot separate paranoia from knowledge. The more you know, the more possibilities you see. The more possibilities you see, the more possibilities someone else sees. The more "someones" there are, the more "they" there are. It's a matter of simple math before you realize that They might not like you.
When computers (people) are networked, their power multiplies geometrically. Not only can people share all that information inside their machines, but they can reach out and instantly tap the power of other machines (people), essentially making the entire network their computer.
