I have seen discussions on this in other forums and basically it is a non starter.
Whilst pilot less aircraft individually are technically possible now, a automated airliner in a automated aviation system is just not going to happen any time soon, if ever. There are just so many unintended consequences and problems evolving from that it is bordering on impossible not to mention less safe than the system we have now. The other issue of a pilotless system is just the massive infrastructure build to make it work.
All that the tech nerds are doing is replacing one problem, 'pilot error', with a whole bunch of new problems that have not been tested yet, additional to other new problems that they haven't even considered. The old 'unknown unknowns'.
Single pilot is easy to accommodate as it already happens now, whether it is a good idea or not is a another question all together.
