You understand that I can't define something which doesn't exist. When I say qualia or self awareness or that little person inside your mind that observes the world through your senses, most people know what I mean.
Let me put it this way. Consider the AI program that observed everything you did for the last several years until it became so good at predicting your behavior that none of your friends or relatives could distinguish it from you in a Turing test environment. Unfortunately the building containing the only copy of the program is on fire. It is just you and the computer in a room rapidly filling with smoke. There is just enough time either for you to get out, allowing the only copy to be destroyed, or for you to upload a copy of the program to a remote site over the internet with your last dying breath. Which do you do?
If you got out, then you must believe in this nonexistent thing. Otherwise you would logically conclude that by preserving your memories in a form that can be backed up, that you become immortal. Furthermore, you have the opportunity to enhance your intelligence and your environment by running on more powerful computers and embodied in better robots in the future. Why would you ever allow one copy to be destroyed now and the only other copy in a few decades?
Sorry for my ambiguous use of the word "you".

... sorry, but i do not get the whole problem. even if a clone of me would walk up to me right here and now, having sufficiently enough of my memories and claiming to have my 'identity', i would not care if this 'double' would not use my resources (e.g. credit card) and bureaucrats would leave me alone!
cheers,

Humans do have such a concept, which we associate with a lack of conscious experience. So we all desperately want to preserve this thing that does not exist. We can't help it. We are programmed that way.

In practice, any creature with a human brain that could say "Ouch, that hurt" has an internal process isomorphic to what we experience as consciousness.

So you hear something like dit-dit-dit-dit-tat. When you do this, a very banal observation, dating back 25 years, is that the brain reacts to the different tone at the end. That reaction, which is called mismatch negativity, is completely automatic. You get it even in coma, in sleep, or when you do not attend to the stimulus. It's a non-conscious response.

>Consciousness, according to Dr. Dehaene's findings, is how the human brain gets around certain limitations of being an analog computer. If you've read Eliezer Yudkowsky's posts you'll know that his approach to AGI would not necessarily call for the AGI to be conscious in the sense we understand. I recall he said "I'm not looking for the AGI to be a new drinking buddy, at least not at first" or words close to that. Paramount, to him, is that the AGI be Friendly, and not damage us intentionally or otherwise. While the human brain is a kind of analog computer, and much research is now
> afoot to emulate it on digital computers, our minds are not exactly computer programs. They are certainly not fungible programs running on a general computing machine, but rather embedded in the structure. The mind is not fungible unless the neural structure is made fungible, which may or may not ever be possible.
>To sum up, there's no real-world way a zombie could react as if conscious, using human brain architecture, without being conscious. Unless you believe in magic. And the subject of zombies, even if such could exist, probably doesn't really apply to the problems of building an AGI.
