## The Sum Total of the World's Knowledge: 250 Exabytes168

arkenian writes "The BBC reports on an article in Science about scientists who calculate that the sum of all the world's stored data is 250 exabytes. Perhaps more interestingly, the total amount of data broadcast is 2 zettabytes (1000 exabytes) annually. In theory this means that the sum of the world's knowledge is broadcast 8 times a year, but I bet mostly that's just a lot of American Idol reruns."

How much of that is pornographic "knowledge"?

250 exabytes ought to be enough for anybody (and everybody).

In UNIX, that's what we used to call the "sticky bits".

How dare you suggest that every byte on /b/, or every "frist psot, I for one, in soviet russia, you insensitive clod" on slashdot isn't knowledge of the first order?

Nice way to conflate terms for a sensational headline. What a bogus metric. A good chunk of that "stored data" is junk. Probably most of it. Not to mention duplication. (Duplication? I told you not to mention duplication :-)

Sorry, i'm just increasing world's knowledge database at the moment.

Wrong math. At best what you there have 125 exabytes of knowledge and 125 exabytes of anti-knowledge. Ok, probably the knowledge weights more than the antiknowledge, so for each scientific paper could be a hundred pages on ovnis, a thousand lolcat videos, and. well, hundreds of spam pages, but somewhat we keep going forward.

How many Library of Congresses is that? I just have no perspective without it being expressed in LOC units.
