Jockey69 - Your line of thinking seems to suggest throwing out the baby along with the bath water. With that perspective we would not be flying at all.
Technology advancement has involved taking risks to explore new horizons. We all owe a debt of gratitude to those how have been pioneers in these areas. Our challenge now is to take the knowledge available and apply it to design and operation of commercial transport systems in such a manner that the risk imposed on the travelling public is reduced to an acceptable level - far below that encountered by the pioneers. We cannot push that risk to zero, but we can make it very small.
Part of our challenge is also to make commercial air transport as affordable as possible without increasing risk above an acceptable threshold. FBW control system technology is playing a major role in that evolution. With this comes dependency on feedback augmentation to provide acceptable handling qualities while enabling performance optimization.
As long as there are failure scenarios that can disable or corrupt data vital to performance of the flight control system in its full up configuration, there will be need for means of recognizing that corruption and gracefully transition to reversionary control system modes employing a smaller, more robust set of feedback signals.
Pilots must be capable of continuing safe flight and landing in all control system modes to which they may be exposed. Training should be defined with consideration for control system mode reversion so that flight crews have both the confidence and skills needed for the task.
