Clay Shirky on Our Cognitive Surplus (video lecture, 1 hour 25 mins, 380Mb)…

“Since the post-war boom, we’ve had a surfeit of intellect, energy, and time — a cognitive surplus. Shirky argues that this cognitive surplus — rather than being some strange new departure from normal behaviour — actually returns our society to forms of collaboration that were natural to us up to and through the early 20th century. He also charts the vast effects that our cognitive surplus, aided by new technologies will have on 21st century society, and how we can best exploit those effects.”
