Of course, Post Civilization is a slow motion phenomenon.
All systems break down, but I'm thinking this drift toward entropy is going to be a very slow, no, a painfully slow ebbing.
If the apocalypse comes it will be a supremely boring event. We might even sleep through it. And then one day, we wake up, and we find that the earth has moved beneath our feet.
The old world gone, a new world birthing.
