Before someone from the "old school" jumps on me, let me point out that while the technology has played a great part in improving safety, there is a well-documented side effect, namely:
It's possible to Murphy-proof the daylights out a system, to the point that a minimally-trained operator (pilot???) can make it work pretty well 99.9% of the time. But if this becomes a way of life, then safety starts sliding downhill again - we see this in the third world.
Put in other terms, we start raising a new-and-improved generation of "Murphies".
(My corollary proposition: One pilot should always be over age 60!)
