I've got in the vicinity of 20 years before 'nominal' retirement.
I predict when I retire:
1) there will still be pilots sitting in the drivers seats.
2) the airlines will have spent at least 5 fruitless years of market research trying to convince the public that pilotless aeroplanes really are safe.
3) the systems and technology will be pretty good, but manufacturers will be reluctant to invest huge amounts of money producing said aeroplanes lest noone wants to fly on them.
There is a huge difference between having an aeroplane which can fly from A to B without a pilot (including taxi, takeoff, landing, etc) and getting Mr & Mrs Joe Public to buy a ticket on one. They (pilotless aeroplanes) are great for sending into war zones, but not much good for passenger transport.
