Nana isn't sure exactly how Gesara will actually work out. I do not believe some of what I hear because I know that flooding the world and people with wealth overnight would destroy the economy of the entire world.
So we will see how it all works, I would say somewhat of a more grandual thing with a gradual introduction also of new technology so as not to up end everything at once.

We must have time to make changes to new systems. For instance with new energy we must have ways to manufacture the materials for such things. These sort of changes could never happen over night without completely upsetting everything to the point of being destructive.
