Couple of points
An airliner doesn't need a pilot it needs a crew , Ok one is in overall charge and normally has more experience but they swap the handling and monitoring roles.
We all know that when computers get confused they just stop - no good having 'Err 404' or 'no internet connection' at 200ft on finals is it.
Someone used the financial trading analogy but that is a cowboy industry as we have now all learned and using the computers like they do and the disasters caused we would be seeing a tens of thousands of people killed every ten years or so when the computers on airliners ran into the depression/panic selling modes the markets do.
At the end of the day i don't think even the most ardent lo cost at any price /fly to an airport 100Km from your destination at 0300/ Buy crap food on board and lotto tickets/ have no customer service at all / passenger will ever get on a plane with no windows up front and no living breathing forms behind each one.
However with automation confusion being a big cause of accidents these days it would seem training needs some revision , engine out at V1 was a regular occurence on pistons and still quite frequent on 707 era jets but today?????
