I'd resist making any predictions or saying "never" to drones. 20 years ago we fought a war in the ME with dumb bombs, no Internet and no drones. Now, drones are soon to replace most combat aircraft, the Army uses a drone helicopter lifter (Kaman Max) and drones are being tested on carriers--Top Gun will soon be Top Desktop.

Self-driving cars aren't far off and no one would have believed it 10 years ago, after 9/11, I might note. Pretty recent. As far as pax are concerned, an airliner today might as well be a drone--pilots are locked in, rarely seen. The whole process from ticketing to flying is designed to eliminate the thought of what's occurring.
