Sensors will continue to break in future. Bits will continue to flip. Wires will continue to fail. Connectors will continue to corrode. People will continue to be humans.
It is the damned duty of every OEM lead design and certification engineer and every FAA, EASA and have you representative to think of possible failure modes and ask for solid and sane design.
It is not the duty to think about saving money by keeping a 40 years old certification in place. Which lets the boss, the boss of the boss and the boss of the boss of the boss smile.
It seems basic airmen and engineering knowledge is lost in the industry and substituted by plain software commodity engineering skills, that are typical for games, desktop software and iOS apps. These do not run airplanes.
Not the only thing that is lost in this world.
Spot on post. Sums it all up succinctly
