Collective intelligence

edublogs: Kevin Kelly@Pop!Tech: Where does collective intelligence begin?

Kevin Kelly gives some astounding insights on how the web resembles the human brain, in his Pop!Tech 2006 performance.

The web is currently being clicked on 100 billion times per day, with over one trillion links. This is the same number as there are synapses in the human brain. Likewise, one quintillion transistors make the web go around, which is about the same as the number of neurons in the human brain. There are 20 petahertz synapse firings on the web and 20 exabytes of memory – the parameters of the web as a whole entity are very similar to the human brain. One problem: our brains are not doubling in size every 18 months.
