All you gotta do is watch a few episodes of "Aviation Disasters" to conclude that the pilot needs a backup - the copilot. After all, when the pilot goes to the potty, who is flying the airplane? The computer? LOL. When something unanticipated goes wrong, the computers are COMPLETELY USELESS because it wasn't programmed to deal with unanticipated problems. Me, I'll pay a bit extra for my flight to have 2 pilots. Pilot…
But would that pilot have to be in the plane to fly it? We have been using remote controlled killer drones for years now.

I think with planes carrying humans we don't want that track record, especially if you calculate crashes per mile flown.
