Those who say that computers will never beat Sully to land an airliner on the water or fly an aircraft with bad damage like Siux City are exactly wrong. That is exactly what computers are good at.
With the benefit of hindsight the computers might handle the mechanics however I'm far from convinced "AI" is anywhere near able to handle the decision making processes that saved lives in both those accidents, and of course not everything is in the ECAM - the BA Triple with the double engine failure probably only cleared the fence/buildings/road traffic in the 27 left undershoot at LHR because the commander made an inspired out of the box decision to reduce the landing flap setting - that's not an action listed in the ECL/QRH.
