I reckon almost all of you started from a point that brings to nowhere. Do you know that Artificial Intelligence scientists, researchers, companies and universities are trying to arrive to replicate the human intelligence from decades? The fact that no one reached his goal is so simple that you could probably not imagine.
First of all, the meaning of "intelligence", the way with which we use to mean that term, is completely wrong. We use the old concept of intelligence inherited from classic philosophy, that thought intelligence was only relative to the faculty to use logic. Unfortunately (for all the people who followed this road), intelligence is something more complex than logic.
I exort you, if you really want to know how the real things are, to make some interesting reading on some of the discoveries of the modern psychology. Take a look, for example, to Antonio Damasio. He is one of the most important living scientists who have studied the behavior of the human brain. In 1995 he wrote "Descartes 'Error", with which "flips the cultural tradition that has always devalued emotions because could disrupt the serenity of reason and shown that, on the contrary, they are essential for good functioning of the mind: if a man loses emotional capacity is not able to be reasonable."
Damasio says his theories through scientific evidence. In fact, he makes reference to a patient's clinical study (patient's name: Gage), as a result of an accident at work. Gage had an iron bar of 110cm that, from a cheek, smashed the skull ( from the inside ).
By chance or miracle, Gage remained alive. But what happened in his brain was extremely interesting ( for science, much less to him ) . Before the accident, he was balanced, polite, clever and shrewd in business. After that, Gage became bizarre, defiant, unable to make profitable decisions for himself or to plan for his future as a social being. This is due to a lesion in the prefrontal cortex.
From this discovery it was realized that there are, in our brain, some areas that "manages" emotions and others for logic (although some have been used for both functions) . Gage was no longer able to have its own sake, nor to perceive pain. The part, so to speak, of his emotional brain does not work anymore, or at least work only partially and very bad. He was able, however, to perform all the logical operations of which he was capable before. So the logic in his brain, didn't receive any damage.
There are a sum of other scientific evidences of the importance of emotions and, more in deep, impulses into the development and maintenance of intelligence that only a part of the science, inside Artificial Intelligence field, continues to ignore.
Without emotions, any AI model can't "think to itself" and then be really intelligent. And if you want to say more, I could also say that emotions are the "reinforcement" that led humans build new parts of their mind to work with logic, and the consciousness is the counterpart of emotions, and is a "reinforcement" too, that natural selection brought to combat against emotions and then balance their exceeds (emotions, alone, can harness the logic of our mind and bring us to make choice that lead us to prove pleasure soon, despite what could be better for the future, but this is a more difficult part of the matter; if you want to go in deep, please wait for a couple of week to take my book "Biological Behavioural Model", or ask for information to some experts of Evolutionary Psychology).
What I want to say is that I could answer to the thirst question of the thread: if we continue to think that intelligence is only logic, not few months, but neither a billion of years could be enough to fulfil the goal of creating a virtual human mind.
