I already covered that part.

Pilots are supposed to rigidly follow their checklists - to the point of having to execute some of them from memory. A computer could easily do the same for the vast majority of emergencies.

The "Miracle on the Hudson" is called a miracle for a reason: the expected outcome is for everyone to die. Same with UA232. Nobody would've blamed the pilots if there had been zero survivors! Even with human pilots it is the exception, not the rule.

The fact that you are willing to blame an autopilot for not improvising a 1-in-1000 Hail Mary attempt is exactly the conservatism I mentioned: we prefer routine human failure and the occasional miracle over predictable automated performance.
