Consciousness is not a program but a set of feelings that arise from millions, even trillions of life-preserving 'programs' (in the case of man). It is an EVOLUTIONARY outcome, not an outcome of intelligent design.
Only living things can 'feel', for these (feelings) are biofeedback signals of various elements of the "life" program.
So here is further proof that Kurzweil is wrong about the Singularity representing consciousness. It is ONLY about intelligence, which is but a minor sub-set of the processes that protect our existence. I have no doubt that computers can become intelligent (in a SUBSET of the fields of intelligence) by 2040. They will therefore help expand the mind of man. But will NOT take over mankind.
I CAN'T AGREE WITH KURZWEIL ON THIS. I disagree with his definition of consciousness. "Intelligence" is not consciousness.
"When computers do reach the stage that they can compete with, or outstrip, humans in intelligence, Kurzweil said that he is ready to accept them as conscious beings. There is no experiment that can be run to determine if an entity is conscious, he said, but robots and computers will likely someday claim to be experiencing it. He described accepting their consciousness as a “leap of faith” that other people will take too." [Source]
Sharad Bailur How do you know that I am conscious? The concept itself is subjective. Hence the Turing test and other such attempts. We may never know that a computer is conscious except when it tells us so. And since we built it we may not recognise its telling us so, as consciousness. This is an issue that needs to be solved first before we talk about consciousness. But then it takes us iinto philosophy iin the absence of other tools.
Sanjeev Sabhlok "How do you know that I am conscious?" I've dealt with extensively on my blog recently. Basically, life (from which originates any form of consciousness) has a will to live.
You have a will to live. You know that "you" exist and will fight to defend your existence. I explained this in a number of contexts, e.g. Deepak Chopra's challenge to Randi, etc. Let me link a few blog posts on this topic.
All properties of life are crucial in any organism that claims to have consciousness. Being "conscious" without having the ability to act, to defend, to self-sustain, is not possible. That (AI) is a mere appendage of the human being.
Sharad Bailur I am not sure that a desire for survival ( or will to live as you call it) is an indication of consciousness. A desire for survival can be programmed into a computer. In fact Asimov based one of his three laws on it.
Sanjeev Sabhlok Desire for survival is not a conscious "desire" alone – it is an urge at a level far more fundamental. It harks back to the concept of life itself. There are many other characteristics that underpin the "feeling" called consciousness. Just solving problems is not consciousness. A complete sense – and "innate" need – of independent existence is crucial.
Bhagwad Jal Park Yup, the "desire for survival" is a behavior that can I can write a (sufficiently advanced) program to emulate. In fact, this whole point is a bit moot. You can claim that I'm conscious, but you have no proof. On the other hand, I can say that I'm the only person in the whole world who is conscious. The rest of you just act like it .
More importantly, we ourselves are machines. Incredibly complex and sophisticated no doubt. But still machines. Unless one starts talking about things like the "soul" etc.
Sanjeev Sabhlok Bhagwad Jal Park, you missed the point. Consciousness is definitely a program of some sort, but it is not something that is "written", it evolves – through evolutionary fight for survival.
Bhagwad Jal Park Sanjeev Sabhlok If nature evolves it, we can create it given the right tools. The brain is just a physical machine after all no?
Sanjeev Sabhlok The brain is a machine with a PURPOSE. It is an evolutionary tool designed to propagate life. It doesn't exist in isolation, like a "stand-alone" computer.
Bhagwad Jal Park The brain's drive is to make us have sex. Having children is a side effect. The brain doesn't care if we procreate or not. As far as nature is concerned, sex is good enough. It's a different matter that we have cheated nature via contraceptives! There is no "purpose", no intelligent design. Without intelligent design, there cannot be a purpose. By pure chance, the drive to have sex aids procreation, so those genes got passed on. There is no guiding hand here.
Sanjeev Sabhlok "The brain doesn't care if we procreate or not". Bhagwad, I trust you are fully on top of evolutionary theory. It is NOT that any creature "decides" to reproduce in order to pass on its genes. Instead, ONLY those creatures that succeed in passing on their genes get to do anything in the future. We only see those that succeeded: hence only those behaviours that lead to success survive. Others die out.
I don't mean that a "purpose" in the sense of "intelligent design", but in the sense of the logic of evolution: only those creatures that survive and reproduce get to live. This business is purely driven by FITNESS, not by "design".
Consciousness is but a small TOOL to survive into the future. It is like having leg or tail. Just one more evolutionary tool. A tool created for a specific "purpose" (in the evolutionary sense!).
There is no underlying logic for AI to survive into the future as a separate entity. If any AI robot tries to dominate me, I'll "kill" it by switching off its power – or otherwise sabotage it.
Since the AI machine was not evolved into its current form (at singularity) but created through "Intelligent design", it is NOT based on the principle of fitness. Hence its "consciousness" is just a program, not an evolutionary tool.
Unless it demonstrates an ability (and determination) to conquer mankind and possibly enslave it, all AI will be mere automation: an appendage of man.
Only if it is determined to survive on its own, to pass on its 'genes' (in the evolutionary, not "intelligent design" sense) and DOMINATE other creatures, will it display "consciousness" in the wakeful human sense of the word.
Bhagwad Jal Park I agree with most of what you say. There is indeed no "decision" to reproduce. Similarly, no creature "wants" to pass on its genes either. All creatures care about is having sex which so happens to pass on genes. One can say that the desire to have sex is directly linked to "fitness".
Consciousness is definitely an evolutionary tool. But if we understand how that tool works (and there's no reason why we will not be able to do so), there's nothing to stop us from transferring that tool onto any mechanical device if we know how.
Also, a machine can be conscious and STILL be an appendage of man. Unless some scientist or programmer decides to program it to survive and reproduce, or whatever. Which might very well happen. In fact, I don't see how it can NOT happen.
I can very well program a creature with an imperative – "go forth and reproduce"! No one is stopping me.
MY LAST COMMENT: I am glad that Bhagwad agrees that consciousness is not a simple 'program' but an evolutionary tool to preserve life. I think Bhagawad is being arrogant to imagine that he can "program" something to reproduce and give it the properties and 'needs' of life.
I am pushing that event back another million years. This is not to prevent people from writing such programs or making progress. Simply that this is not something that will happen soon.
THIS CONFIRMS MY VIEW THAT CONSCIOUS ROBOTS AREN'T ANYWHERE ON THE HORIZON.
"Consciousness is … something physical. Consciousness is always supervening onto the physical. But it takes a particular type of hardware to instantiate it. A computer made up of transistors, moving charge on and off a gate, with each gate being connected to a small number of other gates, is just a very different cause-and-effect structure than what we have in the brain, where you have one neuron connected to 10,000 input neurons and projecting to 10,000 other neurons. But if you were to build the computer in the appropriate way, like a neuromorphic computer [see “Thinking in Silicon”], it could be conscious." [Source]
