Future of warfare is going to something more like Command And Conquer game, where operators will direct autonomous machine with a click of a mouse and warfare will be mostly done at a distance.... Probably with less casualties overall...
Imagine Iraq occupied with pretty much only machines and Iraqis never actually see an American. And if this removes the threat of death from one side, what does that do to the cost of war? Could it actually make it more common because it is less politically risky? It feels inevitable, but it also scares me.
