When a question is too complex for me to solve by walking through it, I look for another way to solve it.

With the brain, I think the single most important thing to remember about it is that it evolved to "adapt" to whatever environment it finds itself in.

And what is more important to survival than to be able to predict?

Cheers and thanks for the idea.

Road Walker, I'm curious based on your formal learning - I was curious if you've read Jeff Hawkins' book _On Intelligence_, and if so what you think of it? He puts forth the hypothesis that the brain is a prediction machine and functions by constantly comparing inputs to a predicted reality. He sees much of the wiring of the different layers of the cerebrum as feedback loops that allow these types of comparisons. He thinks models of the brain as "one-way" are wrong - that the brain is built primarily to soak up info is not correct and thinks that's part of why AI has difficulty. He talks about there being more outbound activity (what he calls the brain comparing it's predictions to what it expects) than inbound (input from senses) and how researchers haven't explained it well or tend to discount it.

It sounded interesting to me when I read it, but I'm not educated enough to have anything other than a "wow that's a cool idea" reaction to it. Thanks for thoughts, if any.
