The technology is there and has been for several years now.
I can assure you that the technology doesn’t exist to make a passenger aircraft pilot less and autonomous. There is no computer currently available or will be available in the near future that could provide the artificial intelligence that would be required by the authorities to make pilot less passenger carrying autonomous aircraft a reality. Having the aircraft remotely piloted from the ground is possible but the expense of doing this would be prohibitive therefore the airlines wouldn’t take it up.
You may recall that last year? the Americans flew a pilotless A/C from the USA to Australia, non stop. Then it returned.
I think you and others here are forgetting that military UAV whether they are the Predator or the Global Hawk, have been built to be expendable. That is why they are unmanned. Infact the Americans have lost quite a few due to tech problems and sending them into hostile environments.
