Answer: I'd say change them
Explanation: I think it depends what rules we are talking about but we are evolving and the rules need to evolve with us. If you look at our government, that's why our founding fathers created the elastic clause. This allows us to add and change laws as we see fit while still having to follow the same morals. Think about it, if we could not change the rules, we would have innocent people murdered at witch trials and women would not be able to show their ankles. Change allows us to move forward and grow.
