AND NOBODY IS WRITING THEM DOWN!!!!!!!!
When the big one, or the crazy one, or the alien one - whatever it is - hits, we will have virtually no record starting about 1995ish. Most stuff is no longer recorded in any form that will be decipherable without current tech.
Remember how hard it was/is to understand hieroglyphics?! How about how hard it will be for aliens to figure out a flash drive!!!! Why did all their pictures stop in early 2000's??!! Only a few "artists" still had photographs produced? etc.
Yeah...one of the unfortunate side effects of electronic storage. It's reasonably stable - for now.
Flash memory degrades eventually, recordable CDs don't hold up terribly well, and bearings in hard drives eventually seize up.
Wikipedia somehow needs to get backed up onto some kind of very nonvolatile medium. Inscribe the bits into granite.
It's vaguely like a modern-day Library of Alexandria; a giant repository of information which (nearly) anyone around the world (with an Internet connection) can access.
Best, though rather unfeasible solution: Somehow get some of us off this planet. There's a decent pile of evidence showing that this place sometimes gets a bit fussy, and decides to attempt to wipe out just about every last living thing in existence. Roughly paraphrasing Neil DeGrasse Tyson, 99.9...% of all living things ever to exist on this planet are dead now. It's not a friendly place to live.
All your eggs in one basket...
Next best solution: AI, something more durable than us, and potentially more intelligent, and see if it wants to volunteer to go on a deep space mission: Our gift (infection?) to the galaxy, of our own breed of sentience.
(And knowing how the Universe seems to enjoy screwing with people, the only two things that'll survive the apocalypse will be the Youtube and Twitter serverfarms.)
