I'm not sure about the AI thing I mean, how do we know how an AI would behave? For all we know, since they didn't compete for millions of years in evolution, they might not have a 'survival of the fittest' view towards life.
Humans are a lot more intelligent than we give credit to ourselves, it's just that we don't know who to use that intelligence correctly. For instance, there are some children (ortistic) who have wierd abilities because of their ortism, in the way they can concentrate their mental energies on one task so completely, it is as if they are a machine themselves.
1 kid, about 5 years old was found in the hospital bouncing a ball up and down a wall with his twin brother. Whenever he caught the ball, he would recite a prime number, the next highest with no discernible difficult, hesitation or limit to the number. He had not been taught prime numbers, but only the most basic numerals. Conversly, there is a caretaker at an obtuse university that can tell you what the weather was like in any day of his life, and also what day of the week it was on any year.
Humans you see, are already vastly complicated organic machines. The human brain just lacks the will to grasp these complex things... thus 'consciousness' itself is not some kind of gift, but a 'block' to thought. The boy who could do the prime-number thing a majig could not do so while in a conscious state, and as he is now older he could not replicate the feats of his youth. I attribute this to 2 things:
Language
Being aware of the world around you
Language as we know makes us of words, and words we use so much they ingrain themselves into our conscious thought, not just when we speak. You cannot think the mathematical equivalent of 'how are you' but must think 'how are you'. This would ordinarily present no hindrance, however, their is also a speed factor. When we speak to other people, we must speak at a certain rate, or they won't understand us. While pitifully slow, this rate is the only way we can communicate. Thus, not only do we bog down our mind with words, but also with the slowness with which we use them.
Being aware of the world has an important effect too, as we cannot be aware of it at an AI speed of thought without becoming bored very quickly. In fact, there is an automatic reaction to this 'speeding up' of our mental processors which does in fact occur at certain moments in our lives when emotional, hormonal, or other processes reach a certain stage in our bodies. This reaction is to slow down. If we did not, then our thought would be out of synchronisation with the world around us, and we would end up mentally defective.
The neuron pathways in our brain are much more complex than the entire planetory network of Earth, but hampered by flaws which are even larger.
