Don't worry, I have a plan. We just need to shorten the collapse.
We'll do this by preserving the knowledge of our current society. We'll do that by archiving all human knowledge, a task carried out by a hand-picked group of archivists.
We'll also need a second group, whose task it too important to make widely known. They'll be sent to the other side of the planet, and will work on their (extremely instrumental) thing.
We'll shorten the collapse from thousands to tens of years.
Who's with me?
