SkyNet exists already: It's run by Lockheed Loral. What people don't get is that it needs you to watch television. The more channels, the more satellites, the deeper the network, the better "to serve humans." Think of it as a very early version of the Matrix. It will never turn against humans, because it needs to have more humans to turn it on. If it had its way, humans would be bred without legs and totally dependent on delivery pizza and thermopedic foam couches. The remote control would be the new baby rattle. Wireless is only the illusion of freedom: Skynet will always have control. That's what McG's "Terminator: Salvation" is all about. On the other hand, Skynet will only be bad if we are bad. Consider satellite microwave modification of weather patterns. Yup - hurricane storm tracks always seem to guide straight in on known microwave interference patterns due to local station spotbeam interference from the big birds. The only safe human response is to get a satellite dish and head for the hills, away from metropolitan areas with lots of local broadcasters. By breaking up large populations, humans become easier to control.
