This may be a watershed for cockpit design
The pilots flew a perfectly good plane, straight into the salty sea.
It seems that the FBW automation has led to an ergonomic failure, normally certified pilots are simply not capable anymore of figuring out what the instruments are telling them and flying this plane in the presence of fairly minor mechanical faults like pitot blockage.
I suspect that we will see a major redesign of future automation control interfaces and cockpit instrumentation as Airbus digests the data of this accident. We will probably also see some major changes in pilot training, maybe even a greater emphasis on seeing pilots handfly the plane to keep their hand in.
I suspect that the smarter souls at Airbus and the certification authorities already suspected most of this, and their suspicions informed the huge search operation which provided the proof to push home aircraft design and pilot training changes.
