So if you take Wikipedia as a kind of unit,
all of Wikipedia, the whole project--every page, every edit,
every talk page, every line of code, in every language that Wikipedia
exists in--that represents something like the cumulation of 100
million hours of human thought. I worked this out with Martin Wattenberg at IBM; it's a back-of-the-envelope calculation, but
it's the right order of magnitude, about 100 million hours of
thought.
