Once more my handler comes into play: (the "Gretchenfrage" in Goethe's Faust)
Does the human have to adapt to a new system, or should the system be designed according human performance?
Or more directly:
Are humans capable of handling such complicated and sophisticated marvels in stress situation, or is the last resort, the human pilot, overwhelmed with the mess such marvels sometimes leave him alone with?
Maybe the initial question of this thread gives a simple answer.
There are many Airbusnauts on these threads, each and every one a wizard on his own and i am sure they would handle every emergency perfectly on their Airbus (if they even fly one ......).
But we must consider the average John Doe, or Yo Nh Doh for that matter, and ask above questions.
