Antikythera mechanism possibly older than previously thought?

I was actually thinking of the plague specifically in my last post. 2/3rds of a society go the way of the dodo and we didn't lose much. Half us of would seem like it would have a smaller effect, though IDK...maybe if the comet miraculously landed on every school and library - getting just the right half..and associated support..maybe?

A magic comet.

Not a magic comet, but one the size of the Dynosaur killer 65 millions of years ago would do the trick. Devastating fires on a global level, followed by nuclear winter for years.

That is, if there aren't any precoutions taken. I'm pretty sure, if there's any such event on the horizon, people wuld actively look to preserve the collected knowledge in underground facilities.

Bad event for the people at large, but knowledge and a fair amount of people being able to teach it, would survive.
