Heres a thought, airplanes are almost all computerized now, pilots really dont do much but be there for emergencies, and maybe do some controlling of the driving around the runway to get into position. But theres still pilots. Its going to be the same with self driving trucks. Truckers there for emergencies, and probably to do the docking. but 90% of your job is going to be like a pilot in a "self flying airplane"....sitting there enjoying the view, ready to take over if s**t goes down. Just my opinion i guess.
