Hm... I guess the argument here is something like: we don't build 10,000 F-35s because we can't train 10,000 pilots. But with drones, the pilots are no longer a limiting factor so we can plan to scale drone production beyond what we do airplanes?
Yes, plus the fact that the craft does not need to be as complicated as the F-35 because it can omit everything related to keeping the pilot alive and functional.
