Whenever I can, I try to think of modern events from the point of view of archaeologists digging through the layers, at some point in the distant future.

Given that perspective, my thought was: "Hey Bob, look at these morons, they called easily proven lies 'post-truth!' Can you believe that? In a civilization based on science, with AI, nuclear, and biological weapons?! No wonder they died out right after this. How did they not see this coming? Anyway, what's for lunch?"
