UAVs and autonomous aircraft and USAF acquisition of the same

I'm listening to a 10-May-2009 60-Minutes podcast on the subject of UAVs (the remotely piloted Predator in this case). They said that next year, for the first time, the USAF will buy more unmanned than manned aircraft. This subject continually fascinates me in that the human is the real weakness in an aircraft (weight, physiological limits, endurance and so on). It's kind of funny in that UAVs are somewhat similar to outsourcing a job. In this case, the pilot's job in the aircraft is being outsourced to a pilot on the ground. Autonomous aircraft for surveillance (Global Hawk) are performing well. The potential for armed autonomous aircraft (UCAV for example) will be realized someday. I think that the end of the "fighter pilot" (sitting in the fighter anyway) is in sight. While that's the one job I would like to have had most in life I can see the likely future for it.
