It's a bad mechanical design, Boeing didn't want to spend money on retraining pilots, they asked software to fix it, software fixed it so that it remained the same, software had a bug, training didn't incorporate new system, because that was the point of the software, to not require a new type rating. I think this is process failure from start to finish. Any sufficiently complex system will have bugs in it, whether it's software or not. I think the other failures are much worse. You have to account for your system maybe failing and your pilots have to be trained to deal with this failure. And yes, software kills people, but no software kills even more people. Just look at how airplanes, cars etc. have improved safety through assistance systems.
