Technical innovation is a capital expenditure that pays off large returns in the long term.
Technical innovation permanently removes/drastically minimizes OpEx for those willing to put up with significant capital expenditure (in building the Technology in the first place): but once done, those jobs are gone.
It made mining, telephone, retail, manufacturing etc companies drastically minimize their dependence on human labor. These are salaries that will never ever need to be paid that goes directly to the bottomline.

New companies are capitalizing on this to establish future oligopolies: https://www.quora.com/What-controls-help-ensure-the-growing-...
Sure, there will be human intervention required for edge cases but it will be humans augmenting technology, not technology augmenting humans in transportation.
Electric (and autonomous) vehicles are going to be the next PC era that is going to change the world for decades and build the new billionaires.
