Do you think we'll have another dark age(s)? Or are we past that kind of stuff?

[Mr Downtown]

Past that kind of stuff. We have an incredible amount of knowledge tucked away in books that nearly half the planet's inhabitants can read. We have lots of possibilities for energy sources, and if one starts to become scarce, the price will rise enough that we'll conserve it. We are remarkably resourceful primates.

The things to worry about are a serious pandemic or a big volcanic eruption that would reduce sunlight in the temperate zones for part of a growing season. But even in those cases, we are now such an interconnected, intercontinental society that aid could easily flow to those affected.
