Plenty of people on this thread are in favour of pilotless flight now or in the future. Not a single one of them is a qualified and experienced and current Airline Transport Pilot, I strongly suspect. Their views are therefore worthless, IMHO.
Until you've gone around late due to windshear/squall for example, and then made an immediate low level turn to avoid a Cb, and then decided upon a practical level-out and a quick required course of action/navigation based upon fuel status, alternate weather, other diverting air traffic volume, and the unforecast weather, at destination, then you know squat. (I was part of a 2-crew op that faced this precise scenario at CUN last year, fortunately in a serviceable highly automated aircraft. What followed successfully was in no way a series of automatic reflexes, way off what could ever be programmed in the next hundred years)
Ignorance is bliss for so many of you armchair pilots. Enjoy.
