Don't get me wrong, I am anything but against automation. In the
situation you describe limiting the impact of the pilot commands
can be compared with say current limiting of the output of a power
supply, nothing wrong limiting it such that it won't get fried
because one turned a knob too much or something. Then all the
large airplane controls nowadays I imagine are with servos etc.,
nobody in his right mind would allow pilot access to the
firmware of these things which say controls the PWM of the
servos.
But above a certain level the pilot should be able to disable
some autopilot thing which causes nosedives because it went
bananas.
BTW there is a nice short story from about 50 years ago by Lem,
"Ananke", built on that kind of stuff (just a nice reading so
I am mentioning it for those who are lucky to not have read
it and can enjoy it now, one of his best IMO).
