Flying is relatively simple... why? Because you don't have to plan for the eventuality that an obstacle is on the tracks, or a 3rd world country fishing boat is crossing your shipping lane.
Virtually all obstacles that are in the air give an automated system enough time to plan for evasive action.
There is never just one cause for an accident, but unfortunately, we humans have a habit of facilitating multiple errors leading to disaster through a number of behavioural and psychological properties that, as you point out, also happen to be strengths on an interpersonal level. Of course I'd rather not go to bed with a computer, but when it comes to flying an aircraft, routine jobs and the likes, I'll take machine over man any day.
