It's not that I believe handling skills are the simple solution - it is the lack of need for those handling skills, as automation has improved, that makes us lazy and over-reliant on the automation to always 'do the right thing'.
Unfortunately, the automation so regularly does the right thing that we stop questioning it and it takes a major deviation before we wake up and realise our magenta line/heading bug/route steer is taking us to the wrong place.
So perhaps, whilst a great deal of training is used to master and manage the automation to get the best out of it, a certain amount should be spent on recognising and dealing with the insidious nature of its failures.
