I'd lose more if Wikipedia went away than if Google went away - the 90s/early-2000s substitutes for their products were usable, just required a bit less blind trust and a bit more effort (and remember: google isn't a magic no-effort-requiring box still - it just guesses right more frequently than it used to).

But there was nothing I remember back then like Wikipedia. Encarta? Extremely limited in comparison. (Or anything then that was like Amazon, for that matter.)
