Exactly. If pilots (humans) cause errors, the safest system removes them from the equation as much as possible, except in the parts of the process where it would be more error-prone not to. Point re: screwing up because the plane is normally flown for you; yes, but that's still safer overall without a doubt than optimizing for pilots doing much of the flying manually much of the time. Occasional emergencies are far better than predictable human error all the time.
