In an abstract way, the information flows surrounding the Tsunami of December 2004 structurally resembled those preceding the Pearl Harbor and September 11 attacks. The raw data announcing the unfolding threat was there, yet the pattern so evident in hindsight was invisible to those who were not looking for it. But if tsunamis and asteroid strikes are rare events, they are comparatively more common than that still rarer object, the unprecedented event: the something that has never happened before. Threats like that can emerge suddenly out of chaotic systems, like WMD terrorism or new viral plagues. Against such events, specific precautions are impossible because no one can prepare for what cannot be foreseen. The real challenge is not so much to create a new dedicated network of staring systems against known threats but to tie current sensors to systems which are capable of cognition. The most valuable survival asset is situational awareness -- the ability to recognize threats you have never seen before and respond in an evolving manner -- and that capability has not yet come to the world as a whole.

Good stuff. Read it all.
UPDATE: I should have looked around a bit before finishing this post, great stuff from Boingboing here and here, and more at Captain's Quarters.
