A simple example would be global warming. Let's assume we have a neural network that is programmed to fight global warming. It would take in all the data and make calculations on how to best fight global warming. It would inevitably come to the conclusion that humans are causing global warming. What would be the simplest action stop global warming according to an algorithm programmed to do just that?

This made me think, you are right in something when a house is infected with a plague one does not destroy the house or move to another one simply eradicates them.
