Joe public doesn't really care... it's those that stand to sue AIB or AF for an epic fail on their part. Of course those parties have a vested interest.
Occam's razor once again: Complex and rare systems failure vs. inattentive crew cockup. It sadly comes back to the latter time and time again.
The problem needs addressed (and has needed addressed for ages) how to avoid these kinds of mishaps. I fear until we are flying 100% automated from gate to gate, there's always ample room for human error of this dimension.
