Past civilizations have risen and fallen, but humans are still around, and they kept some of the technologies too.
So I wonder if we can plunge back into a dark ages type of scenario. But even if we did, could we somehow store the knowledge we had?
In the past, you could burn the library of Alexandria and destroy stored human knowledge/progress. But it's hard to burn a sundial, or sextant, or compass, or whatever other technologies that kept our human knowledge/progress.
If we faced some bad event, like super ultra double-plus world war XXX, I would think there could be people that hoped for the future, and took steps to preserve human knowledge, put it somewhere safe.
I mean technically we stored a bit of human ingenuity and explanation/knowledge on the Voyager spacecraft safely tucked away on the outside of our solar system. I mean that's a pretty good offsite storage if you ask me!
So someone could just create a safe room on earth, or even on the moon, I mean a guy like Elon Musk with his own spaceship company, he could be like yeah put a thing on the moon for safekeeping or whatever.
