It is impossible to imagine, from the other side, what will lie where we are, when we are gone. The science, the inventions, those are the easy bits. Da Vinci guessed the plane, the tank, the helicopter, but no one guessed Nietzche or Marx. Something new will come along, something none of us could imagine until it is here. Not something good or something bad, just something different.
“It is not funny that anything else should fall down, only that a man should fall down … Why do we laugh? Because it is a gravely religious matter: it is the Fall of Man. Only man can be absurd: for only man can be dignified.” G. K Chesterton
