The Internet is a brain

This might sound far-fetched, but compare the two images below. The one on the left is a partial map of the Internet; the one on the right is an image of brain neurons. Jeff Stibel has an intriguing article on this subject:

Let's get concrete about what I mean here. The brain is one of the most complex networks in the world, with more neurons than there are stars in the galaxy. Its hardware is a complex network of neurons; its software a complex network of memories. And so too is the Internet a network. Its hardware is a complex network of computers; its software a complex network of websites. There is a lot we can learn from the brain and it can tell us where the Internet is headed next.
