Some of this actually fits perfectly into the framework of Kurzweil's The Singularity in the sense that you could argue that most neuroscientists are too focused to the complexity of the brain and aren't anticipating the progress that may be possible through rapid evolution of tools for looking at the brain.

The said, I think Kurzweil's plan for constructing an intelligence actually oversteps his basic approach. Tools are advancing on multiple fronts. Not only does that give us multiple ways a singularity could happen (from brain-simulation to simplistic-but-massive-ai to clever-ai to bio-computers) but the multiple advancing fronts could go around apart walls (a sufficiently sophisticate computer could make brain processes look less opaque etc).

Personally, I'd say Paul Allen's counter-argument, which I recall as boiling down to the inherent limits of human-produced software, is the most plausible counter-argument.

Actually, the "new church" is that human nature is something more than physics. Even if Kurzweil is wrong in his predictions, certainly this neuroscientist is also wrong with his metaphysical beliefs that the brain is something more than a mere "machine".

The part of the article that bothers me here the most is a leading nueroscientist asserting that the brain is not computable. That is demonstrably false: The brain is a quantum system, just like everything else in the universe. All quantum systems containing n qubits can be simulated by 2^n classical bits. It may very well be impractical to compute a decent sized brain, but that's still technically computable, which is a serious problem in his whole "you can't reduce human nature to a computer algorithm" tirade. Yes, you can. It will be impossibly huge and slow, but you can.

Thank you for summing that up so concisely. I'm going to try to remember the "so you think human nature is something more than physics?" argument for the future.
