There will be sections where I go into brain function in more detail and using more specific language. However there will also be places where I use more colorful, engaging and inspirational descriptions than a science writer would be likely to use. "Awesome problem-solving machine" is one example.
And in practical/functional terms, entirely true. The human brain developed, over a million years of evolution to solve the most basic and practical problems of surviving in a hostile environment - what will I eat and how will I get it - is this creature, food, environment safe or threatening, etc.
As one anthropologist said, "The human brain did not evolve to ponder metaphysics."
