Summary: The aircraft hit a mountain while on approach to Strasbourg. Design deficiencies with the mode selector switch. An incorrectly set flight control system resulted in an excessive rate of descent that went undetected. The crew inadvertently selected 3,300 fpm descent rate on approach instead of 3.3 degree flight path angle.
Summary: The plane crashed after demonstrating a simulated engine failure on takeoff. Caused by a number of factors relating to the test and actions of the crew none of which singley would have caused the crash. Unexpected mode transition to altitude acquire mode during a simulated engine failure resulted in excessive pitch, loss of airspeed, and loss of control. Pitch attitude protection not provided in altitude acquire mode.

The point being that whether in the case of the A320 and problems with the Man-machine interface or software porblems or problems in construction. New technology gives huge benefits but with these benefits comes new risks and problems. Which inturn lead to overcomming them.
My question was not meant to be a dig or a worry mongering one but more a request for more information. There seems to be questions on potential hurdles to this new technology and not much publicised answers. Possibly because 'how' might be a trade secret who knows
