How Stuff Works has a rundown of the Top Five Scary Technologies of 2008. They're not actually terrifying (and a few aren't technologies), but they make for some decent reading-and post-read pondering.Via Digg.Note: One question on a few of the Digg commenters' minds seems to be whether the Large Hadron Collider will produce an earth-swallowing black hole and obliterate existence as we know it. To that, we have to laugh, with casual defiance, and say: No, it won't destroy us-not if it keeps getting rick-rolled by liquid helium.(Photo via NewScientist's gallery of LHC damage.)
