Drones will likely be cheaper and less of a planning nightmare, unfortunately

It's probably going to be a 'throw everything at the wall' technology future, so drones for sure. They are mostly for light loads though, even a larger drone army would have trouble moving trainyards worth of stuff. There's only a certain density of air traffic you can have before nothing can move.
