It's not just intractable for the human brain simply sitting there cogitating, with its thumb up its ass. It's computationally intractable, too. To know what I mean by that, you'll have to learn something about the kinds of algorithms that run on computers. Even if you use a whole computer (processor) to model the state of a single neuron, you need a lot of these, and they have to communicate with each other at some rate of data transmission. The speed of light is finite, and is smaller in a material medium than in a vacuum. Don't forget to include the hormonal imbalances. There's this old computer geek joke about unsophisticated people who propose big ideas, referring to such people as "vacuum tubes".
