And redundancy? Around 240BC, the first Qin emperor in China had all non-technical books burned. We have much of the oldest Chinese literature because it was restored from memory after his death.
If someone wants to burn it all, and can get enough power, they will find a way.
So you feel that even if we had archives buried in bunkers underground, on 6 continents, that somebody could still destroy all of it? I hear what you're saying about if they can get enough power, I just don't see anyone succeeding in taking over the entire world. I guess I'm an optimist :P
Really? Russia, Japan, the fall of the Ottoman empire, the creation of the state of Israel and its ongoing repercussions, the start of a century of US involvement in South America to protect the Panama Canal and other assets, Mussolini, Libya, Tunisia, and Morocco were not enough for you? China lost 14 million people to WWII...
WWII is pretty much singlehandedly responsible as a turning point for the ongoing mess in South America, North Africa, and the Middle East.
of course, you'd have to be ok with photocopies instead of originals. for the purpose of preserving information, i dont see a problem with photocopies.
