55 Trillion Links

Consider the Internet as one global machine.

In his talk The Next 5000 Days of the Web Kevin Kelly presents a spec sheet for this machine (circa 2008):

55 trilion links, 1 billion PC chips, 8 terabytes per second of traffic, 255 exabytes of storage

In comparison, the human brain has an estimated 86 billion neurons and about 100 trillion synapses (the number of stars in 1,500 galaxies)

“To a first approximation,” says Kelly “the size of this machine is the size in complexity of your brain… however your brain isn’t doubling every two years. If we say that this machine (the Internet) is one human brain, by the year 2040 this machine will exceed humanity in processing power"
