Yep. No society is immune from collapse. My point is only that
technologically advanced societies are much less so. So, do you think
anyone alive at the height of the Roman Empire was still alive to see
those wolves roaming the streets? No. It took a very long time
indeed, for Roman society to decline and fall. It didn't suddenly
collapse within a portion of a single lifetime, like, say, the Incan
Empire.

The Inca and the Maya were very technologically advanced. Both collapsed in
a lifetime.
