"Brin's talk was a therapy session. 'We need criticism,' Brin said: 'Karl Popper said that if you're not making falsifiable statements you're not making statements.' And he could have added, you only learn when you change your mind."
Brin's point here was, "We have to stop acting out of our own self-righteousness and recognize that we too may be subjects of propaganda." And finally, "Only in an open society can we charge into the future."
A few inaccuracies... but he and the rest of the audience at the Stanford University Conference on Accelerating Change seemed to "get it"... that we need to remain a civilization that looks ahead, with both skepticism and eagerness, toward a future of open horizons. Not one featuring a stage-set drama of the end-of-the-world.
