    There is a big difference between modeling the brain chemically and trying to create a computer as smart as a human by mimicking the brain. For all our faults, the human brain is crazy powerful. Here's an excerpt from Physics of the Future, by Professor Michio Kaku:

    There are serious problems, however, with modeling the entire human brain, especially power and heat. The Dawn computer devours one million watts of power and generates so much heat that it needs 6,675 tons of air-conditioning equipment, which blows 2.7 million cubic feet of chilled air every minute. To model the human brain, you would have to scale this up by a factor of 1,000.

    This is a truly monumental task. The power consumption of this hypothetical supercomputer would be a billion watts, or the output of an entire nuclear power plant. You could light up an entire city with the energy consumed by this super-computer. To cool it, you would need to divert an entire river and channel the water through the computer. And the computer itself would occupy many city blocks.

    Professor Kaku argues that we'll be in midcentury before this task is truly achieved, and we'll take even longer to analyze the data produced.

    Again, I look at this and think medical research. I do not see Skynet or anything of the sort. I don't think it's meant to be an AI, I think it's meant to be a medical model.

    The problems that exist in the world today cannot be solved by the level of thinking that created them. - Albert Einstein.
