Autonomous airliners? Check out the NTSB report on the fatal accident of the autonomous car that drove into a pedestrian and her bike (the list of "objects" and situations those cars can't handle is longer than you think). The lack of training on ethics and human factors is the running joke of the software industry for years (fortunately some take those courses at some point in their careers). Full autonomy means the designers have foreseen and built in every possible scenario into the algorithms. 'Not going to happen any time soon, IMHO. Or perhaps when accident reports will stop to describe operational surprises and unexpected combinations nobody ever thought of (good luck with that one)... Put AI on board then? Who's got the guts to certify such an airplane when the software engineers themselves acknowledge that at a certain point they don't know exactly how things work anymore?
If you can, grab a copy of "The ironies of automation" by Lisanne Bainbridge. It's a 4-page article from 1983 and we haven't made much progress since then.
"Pay-to-fly" schemes will unfortunately carry on for many years...
