The MPL was the worldwide attempt to teach pilots to fly airliners through mainly simulator training. It hasn't succeeded because there is a recognition that the reason pilots are required is that aircraft, despite all the automation, still need to be able to manipulate the controls to a standard that requires training and practice. To all the tech nerd and computer geeks give up trying to claim victory in aviation and concentrate on 2D vehicles, where there is still a lot of work to do.
