Re:As a computer scientist turned neuroscientist.. (Score 1)

It is difficult for me to understand how somebody could build a simulator with enough transistors to create a turing machine large enough to simulate a human brain, when according to Carl Sagan this is a number greater than the number of elementary particles (protons and electrons) in the known universe. I understand that brain is running at a slow frequency, but still, it would take several galaxies worth of matter just to build anything close, using binary architectures. (today's 32/64-bit CPU's are laughable by comparison) Anyone who has been a computer scientist and a neuroscientist should have this insight. Real breakthroughs in CPU architectures are awaiting those who can mimic the brain.
