Indeed, a hyperlink is much like a synapse in the brain. Both work by making associations between nodes. Each unit of thinking in the brain — an idea, for example — grows by gaining links to other thoughts. The greater the number of synapses connecting to an idea, the stronger it becomes. Similarly, the more heavily linked a Web node is, the greater its value to the Machine. Moreover, the number of hyperlinks in the World Wide Web is approaching that of synapses in the human brain. But the Machine contains a million times more transistors than you have neurons in your head. And, unlike your brain, it's growing at a rate that outpaces Moore's law. By 2040, the planetary computer will attain as much processing power as all 7 billion human brains on Earth.
