Well, we've never managed to reduce ourselves to cave-man status since
that condition was left, unless you count folks building underground
homes for ease of climate-control. Contrary to popular imagination,
there was no loss of technology from the fall of the Roman Empire and
"Atlantis" was a result of poor records of a non-existant Golden Age
before the Cretan civilization was wasted by a volcano -- after all,
if times are hard Grandpa always says "in my grandpather's day ...",
but if times are good he says "why, when I was a kid we had to ...".
Legends build from there.
