>Big disasters require many small things to go just right. If the software was more robust this wouldn't have happened. If the hardware was more robust this wouldn't have happened. If the UX had been compatible with the pilots existing knowledge this wouldn't have happened. If the airlines were willing to pony up for type certs this wouldn't have happened. None of those things are small. They are all glaring errors willingly overlooked only because of the last point you mentioned which is money. This is not a case of unfortunate accidents that can advance peoples understanding of avionics. This is a case of serious (in my opinion criminal) negligence motivated by a desire for more money this quarter and the next.
