I would have thought that UAVs have a future in mud moving but perhaps not air-to-air as yet.
Unless the air combat facility is fully autonomous they will require data link to a human on the ground (or in AWACs) who will "fly" the thing. That means a second or so for the data to travel each way via satellite and then be processed by the magic black boxes. One second in air-to-air combat is a HELL of a long time.
Remember also the "intuitive" element that a human can bring. Sometimes a move that the software writer may not have thought of could be the one that gives the edge.
I believe that this means (for now at least) that we can expect to see UAVs chucking bombs at the ground while the manned aeroplanes try to shoot them down.
As for blue on blue - if the ground assets have IFF then maybe UAVs would reduce the risk?
