The industry has stopped blaming things on "pilot error". It's not constructive, and in 90% of the cases it is the wrong conclusion. That in itself is dangerous because it means you stop looking for the real cause and ways to prevent it in the future.

The current view is that a mistake by the pilots can not be allowed to bring a plane down. If it does, the plane, software or procedures are designed wrong. And from my experience the industry (at least in Western Europe where I fly) really lives by this.

I don't represent the industry; I was just responding to a comment about pilot error. I was taking it as a given that we already know the ultimate cause was bad software. But that bad software didn't crash the planes every time, only under certain conditions, and after certain pilot actions or inactions.
