You missed the point:

Detecting the existence of a problem gives you the chance to improve the algorithm that you expected to be perfect!

Think about the recent problems with Rolls Royce jet engines in the Airbus A380. The redundancy of this airplane - it can still safely fly with only 2 of 4 engines working - helped discovering that this totally unexpected problem exists. Now the engineers can either try to improve those engines or Airbus can switch to another supplier.

But without the redundancy they would have no clue now, why the airbus might have crashed.

Absolute security is an illusion.
