I liked the answer John Brockman (editor of The Edge) gave:
"I believe but I cannot prove that we are moving towards a future full of correct answers but this may cause us to lose our ability to ask the right questions. In this age of “search culture”, with Google and other search engines leading us towards unlimited information, we focus on knowing, on ideas of truth and proof.
Many people welcome these technological advances as the first steps toward a universal library. My concern is that we are moving forward blinded by a naive sense of certainty.
When I asked this same question about belief and proof as the annual Edge question (www.edge.org), last year, the responses pointed to the new ways of understanding the world: advances in physics, information technology, genetics and neurobiology. But the researchers behind these new developments did not achieve success by having answers: they asked the right questions."
As Brockman mentions, the same question was asked last year by Edge. Look out for the answers given by Pamela McCorduck (on collective human behaviour), Esther Dyson (We're living longer, and thinking shorter." - could this be the Attention motto?), Alex Pentland ("unconscious social signaling").
