The Air Force has already proven that this concept is on the way. I wouldn't recommend your young children to this profession anymore. The GlobalHawk is a fully GPS navigated and flown (no pilot on ground) airframe. Although the first prototype crashed on takeoff (I believe) this piece of machinery can taxi, takeoff, cruise, descend, land, and taxi to a parking spot within 6 inches of a designated spot. It may be on the horizon for cargo/passenger applications, but having seen a Predator UAV blast terrorists from their vehicle may at least put the days of a manned fighter/bombers in the military to be numbered. I think it will take at least 25-30 years before the public would accept a pilotless aircraft. Maybe they'll hire someone to pull the levers like in a train to open/close the doors and then call them pilots...
