"Cognitive surplus" as the author describes it, is essentially a reference to how we tap into our free time. There is only a cognitive surplus if something productive results from how we spend our free time
The surplus isn't even productive use of free time, it's the fact that free time exists at all in large way (a byproduct of post-agrarian society) and that we're cognitive beings (ostensibly

).
interactive...is of greater benefit than...non-interactive...because it gives people a better opportunity to consume, produce and share, thereby creating a "cognitive surplus".
Everything except the last bit. People, it seems, enjoy producing and sharing just as much as they do consuming. It took a screen with a mouse (and tubes connecting it) to realize this. However, what makes us capable of cognitive surplus is the same
je ne sais pasBy spending our free time in a manner which does not qualify as a contribution to "cognitive surplus", we are extending the psychological limbo of the "gin" and "Gilligan's Island" generation
Right, the inverse of this statement is the $50 question. What will the communications revolution produce? If it's more like WoW, maybe not much. If it's more like stuff from that guy in Brazil, maybe great things.
If we run out of oil/electricity soon, definitely not much
