Ultimately no human brain, no planet full of human brains, can possibly catalog the dark, expanding ocean of data we spew. In a future of information auto-organized by folksonomy, we may not even have words for the kinds of sorting that will be going on; like mathematical proofs with 30,000 steps, they may be beyond comprehension. But they'll enable searches that are vast and eerily powerful. We won't be surfing with search engines any more. We'll be trawling with engines of meaning." – Bruce Sterling
How will we keep up with the "dark, expanding ocean of data we spew"? Algorithms? Social filters? Faster memex-like gadgets? Do we need open algorithms in future search, so that each person can tweak their own preferences? Will we become dependent on social networks to filter the world for us, and if so, are the current representations of social relations too coarse? Will we be spending more and more time creating explicit metadata, like tags, in order to help channel the "expanding ocean"? What does it mean to be smart, today?
