I am fascinated by Drones, the next major problem in our near future. I'm not really sure why everyone is saying "oh, drones are going to replace manned planes." Drones and manned jets have completely different functions and roles in a top-flight Airforce. Drones ARE replacing some of the roles as air-to-ground bombers or strikers, but what they are very good at is reconnaissance - mostly long-rage - and search and destroy from air-to-ground on singular missions (or as decoys in high risk circumstances). However with jet planes like the MiG series, Raphael and FC series, their job is mostly air-to-air fights with other planes, moving fast and with great agility to take down anything in the sky, easily taking out a whole squadron of drones no matter how well remotely piloted. And in turn, in air-to-air fighters, the pilots don't just use sight to pilot their jets, they use their other senses as well, and the immediacy and integration of a pilot just can't be duplicated by a remote control system, and as jets become faster and faster that integration gap is going to get bigger when a nanosecond judgement call makes the difference (even control orders being sent at the speed of light will still leave a lag in a high-intensity combat situation, and relay isn't that fast yet). And the learning A.I. needed to pilot a plane on its own aren't going to be advanced enough for hundreds of years. Pilots in the cockpit are going to be around for a while.
So drones are best for reconnaissance and stealth air-to-ground bombing (and decoys), but manned aircraft with high speed and agility are still going to be necessary for air-to-air combat, and air-to-ground combat situations. It's about using different technologies to their best abilities in the situations they are best suited for. If you try to make drones the basis for your Airforce you're going to get butchered.
