You either make sure it doesn't fail, or you can continue flight without it. Either way, it has to be fail safe.
There is a backup to extend the landing gear if the primary hydraulic system fails, the plane can fly with one engine out, we make sure that even if an engine explodes it does not damage the air-plane, etc.
On the latter point, you can continue flying without autopilot or landing-assenting electronics and pilots are trained to do so.
MCAS has failed on all counts, it has been very unreliable and fail-deadly.
