Why isn't the Internet self aware?

The human brain contains roughly 100 trillion neural connections. The Internet has about 150 quadrillion transistors in its 75 million servers, plus the countless additional ones in all the PCs and Macs and Linux machines and supercomputers connected to the Web. Considering just the HTTP servers, the Internet has 1500 times as many neural connections as a human brain does, and yet it never says to itself, “What am I doing here?” “Who am I?”

If you connect a TV camera to the Web, a computer receiving its signal can be programmed to match certain objects in its view using pattern recognition, and do certain things about those recognized patterns. But it will never think about any action outside its program of responses to patterns.

Why? What is different about human brains that lets us not only execute a staggeringly complex programs in response to visual stimuli, but think about our perceptions and alter our own programming about what to do in response to them?
