In Neuromancer, Snow Crash, Johnny Mnemonic, Hackers, and just about every other chilling pseudo-cyberpunk vision of the future, there are two worlds. One is physical, where Real Death is possible, and where you choke on the pollution of New Tokyo-Beijing or whatever. The other world is virtual. You play an avatar in that world, or perhaps just a disembodied viewpoint, or you get polygonal hands to wave out in front of you, but there is only one virtual reality. If you’re on the network, you’re on The Network.
