There's a terrific video on TED this week from science journalist Matt Ridley, whose recent book The Rational Optimist is making some waves among the community. Ridley's video "When Ideas Have Sex" argues that the one human trait that really separates us from our fellow beings on the planet, is trade and exchange--the ability to combine ideas and specialize. It's an interesting idea, and the video worth watching, as Ridley compares Paleolithic technology with 21st century technology, and discusses Ortvale Klde while he's at it.
