It's a question that's perplexed philosophers for centuries and scientists for decades: Where does consciousness come from? Neuroscientist Christof Koch, chief scientific officer at the Allen Institute for Brain Science, thinks he has an answer.
Koch: There’s a theory, called Integrated Information Theory, developed by Giulio Tononi at the University of Wisconsin, that assigns to any one brain, or any complex system, a number — denoted by the Greek symbol of Φ — that tells you how integrated a system is, how much more the system is than the union of its parts. Φ gives you an information-theoretical measure of consciousness. Any system with integrated information different from zero has consciousness. Any integration feels like somethingto that system. When it's dissolved, it does not feel that anymore. (http://www.scoop.it/t/consciousness/p/3582464734/2012/12/04/integrated-information-theory)
The internet contains about 10 billion computers, with each computer itself having a couple of billion transistors in its CPU. So the internet has at least 10^19 transistors, compared to the roughly 1000 trillion (or quadrillion) synapses in the human brain. That’s about 10,000 times more transistors than synapses. But is the internet more complex than the human brain? It depends on the degree of integration of the internet.
For instance, our brains are connected all the time. On the internet, computers are packet-switching. They’re not connected permanently, but rapidly switch from one to another. But according to my version of panpsychism, it feels like something to be the internet — and if the internet were down, it wouldn’t feel like anything anymore. And that is, in principle, not different from the way I feel when I’m in a deep, dreamless sleep.
