Just look at the raw numbers at that one case. That's 4000 casualties from one non-military detonation. Strategic warheads would target much more crucial areas, be much larger and not initially bottled in concrete (as well as covered with that containment goop afterwards). And with Chernobyl, the entire area was closed to human activity, preventing more long-term effects, and it hasn't really even been long enough yet to stop the count at 4000.

So, 100 nukes would each be larger explosions than Chernobyl and also leave fewer safe harbors for people to run to. If, 100 isn't enough to destroy life-as-we-know-it then, you've stated we've still got 9900 more chances ...

But, more to the point, current NN's are still pretty simplistic. Worse, there's still a lot of "art" to the science. Getting a NN to make reliable classifications takes a lot of "massaging of data" for good results, and I think that's a large part of the problem. The basic theory is there, but MUCH is left in the field to be uncovered.

Actually it's identical to the system used by the Human Brain, all data is considered and added and then the most used paths are kept while the old are removed, exactly what happens in a Human Brain. Remember there are 1000Trillion synaptic connections in a child’s brain, and 500Trillion or less in an adult.

They don't classify GENERAL data efficiently. As I said, they're still very much limited in scope to be effective. And speech aren't so much contradictions, as inexactness (fuzziness, as you call it). What's that, you're saying that software can handle that fuzziness?

That's not what I mean by fuzziness within the Human Brain at all. The fuzziness I referred to would be analogous to a computer arriving at a result while missing one of the operands.

Kinda bolsters my point about humans being meat computers. Our visual programming works in a certain way and we can't act against it EVEN WHEN we know it's wrong. Of course, all the mechanisms that allow us to build a picture to even recognize a vase or faces are the same mechanisms that made sure our ancestors spotted that predator stalking along or that meal running away.

Erm, not really.

Actually, I think it's called the "Planck time" .. something like 10^(-31) seconds (I could look it up, but I'm at work).

Planck's time is how long it takes for light to travel Planck's length.
The Planck length is the minimum length before Quantum Laws reigns, making length meaningless (because of Hindenburg’s uncertainty principle) NOT the smallest possible.

The figure is (roughly) 5.39 × 10−44 seconds, for reference.

True, but I seriously doubt that it would take a meter of infinite precision to EXACTLY ACCURATELY measure the amount of electrical current generated.

If you think of electrons in a classical way, more or less. But how many electrons is that and how many bits are needed, I'm afraid I don't trust your figures. Though now your adding in complexity as you now need an accurate particle simulation as well as an accurate Brain simulation, which is what I've been alluding too all along .

'What is the self, and how can a self come out of inanimate matter?'
This is the riddle that drove Douglas Hofstadter to write this extrodinary book. In order to impart his original and personal view on the core mystery of Human existence - our intangible sensation of 'I'-ness - Hofstadter defines the playful yet seemingly paradoxical notion of 'strange loop', and explicates this idea using analogies from many disciplines.


Quote:

Eh, the uncertainty principle only applies if quantum entanglement effects the decisions which we make.I would tend to disagree with that notion. Sure there are quantum effects in the brain, but, as I stated, I believe they have a minor (possibly non-existent) affect on our cognitive functions. There are different ways to use quantum effects in calculations, but I doubt our brain actually has evolved to do any high-level quantum manipulation. From what I've gleaned so far from responses so far, you may not be familiar with the potential of quantum computing. If you were, you would have been able to dispute me on this basis alone, and that's probably the only argument that I'd defer to.

Quote:

The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.
Heisenberg, uncertainty paper, 1927


The Heisenberg Uncertainty Principle says we can't know the position and momentum of a sub-atomic particle. It also postulates that the very act of observing something sub-atomic changes it. Therefore any Quantum level effects are open to the Uncertainty principle.

Besides this, it is believed that Quantum Teleportation, and just straight forward entanglement do occur within the Neurons of the brain.

I'm aware of what Quantum Computers can offer, but since they are Computers, and they work on pretty much the same principle as Silicon computers, they are still Turing Machines, also conforming to the original ideas laid down by Charles Babbage, I don't see how I can use them to support my argument, except to say I doubt a Quantum Computer could achieve sentient, which I've alluded to.
Quote:

However, it's a rather large leap to assume that the brain uses quantum algorithms, as quantum effects are notoriously difficult to exploit. Greater minds than ours have with trying to actually apply them, and I don't think God's creations could usefully apply any known algorithm except the one for memory recall.

And we're back to the assumption that the Brain is a computer. The brain DOES NOT use or do anything algorithmically. Just as a Photon doesn’t do the things it does algorithmically. The algorithm is how we model actions to be performed on a computer.
Quote:

To be specific, I doubt the brain uses the quantum effects for any of the following potential uses: memory recall, decryption, instantenous (as in Faster Than Light) transmission of useless data, or star trek-type teleportation (yes, it actually is possible using quantum computers). There is one more important, but simple function of quantum entanglement, so *IF* there is ANY use of the quantum effects, then I would suspect that they serve ONLY as a source of true randomness, which, would then defeat predicting human behavior exactly, but serve very little purpose otherwise.
So, even though it wouldn't be very necessary, this functionality can be replicated by software accessing a cheap hardware random number generator.


Firstly there's a huge factual error I can't leave hanging. By the line:
star trek-type teleportation
I can only assume you mean Quantum Teleportation. If ANY QM physicist has made the statement that Quantum Teleportation is Star Trek-type teleportation then I want his/her name so I can have him/her publicly flogged.
Beyond that:

The above raises the question of how such phenomena can affect the functioning of cells. In other words, would the existence of such coherent states and the emergence of quantum mechanical entanglement be somehow useful or beneficial to biological function? Is it then reasonable to propose that in certain cases, natural selection may have favored molecules and cellular structures that exhibited such phenomena? If we accept the notion that according to the laws of quantum physics certain macroscopic arrangements of atoms will exhibit such effects, is it not reasonable then to expect that biomolecules and (by extension) cellular structures and whole cells have ’found’ a use for such phenomena and have evolved to incorporate them? We stress that at a given instant in time, the different microtubule coherent states participating in a specific bulk entanglement would be almost identical due to the fact that they are related/triggered by a specific “external agent” (e.g. the passing of a specific train of action potentials.) This is of outmost importance since it increases the system’s resilience to decoherence (by entangling a large number of nearly identical states), in addition to facilitating ”sharp decision making” (i.e. rapid choice among a vast number of very similar states) as explained in [37] which is presumably a trait favored by natural selection. Here we digress to investigate one possible use of such effects by noting a straightforward application of entanglement to teleportation of coherent quantum states across and between cells.

One final note is that true random number generators use radioactive decay, and are anything but cheap .

Fallout fell on Wales. The isolation or the closing of the area isn't so important.

The IAEA seems to believe that it is long enough; they concluded that 4000 casualties is the total expected impact. 4000 out of a million people under the ash cloud not including almost a million people directly involved with the clean up, less then half a percent of the effected population. Only about a third of million people were relocated, which means that over half a million people continued to live in areas contaminated to levels of ~200 kBq/m² of Cs-137. Numerous extensive studies, including several UN studies, have reported that there is no scientific evidence of any significant radiation related health effects to most people directly exposed to the ash cloud. No discernable increasing in leukemia and while a small (2%) increase of thyroid cancer was observed, it is debated even how much of that is due to Chernobyl, if any.

90% of people under 20 affected by the Hiroshima and Nagasaki ash clouds were still alive as of 1995.

There’s much more then that.

One would expect a nuclear war to be worse then a nuclear accident because of the nature of war, but that doesn’t change what we are seeing in terms of the effects of nuclear fallout, based on the one major accident and the two examples of actual wartime use, and the many tests. The ash cloud is just not as dangerous as previously thought. The evidence for such an assessment has been only recent, but the hysteria has existed much longer and has been instrumental in fueling the debate with nonscientific assumptions. Nuclear war would be nasty, but more then likely, the vast majority of deaths would be decided by the explosion, not the ash clouds.

I'll ignore the above as it seems to contradict most of your other assertions in that the brain cannot be modelled on any sequential system. Maybe you wanted a different word from "identical" .. eh.. either way, I'll let you elaborate on this one

True ... but software can put that counting to use to bring about sentience, if used intelligently. At least, I like to believe so.

Conceivably, a brain could be simply considered an automated, souped-up phone system (inter-connected message passing), and yet, consciousness rises out of that.

There's nothing wrong with that theoretical possibility. By copying quantum states, any object can be teleported. It requires more than just quantum entanglement, though. But, it is possible.

If you need a name, it's probably one of the big ones in QC ... P. Shor, L. Grover, etc.

Actually, I could argue that by pointing out your appendix. Not everything we have is currently used, useful, or even desirable. Again, quantum effects are abounding, and their presence in the brain in not very surprising. No one even has a clue on what they could be used for, and I doubt that sentience requires them. HOWEVER, even if it were a reqirement for sentience, it is NOT BEYOND being replicated in hardware. I would have to revise my design to allow access to a quantum memory bank, though.

I could make a true random number generator by taking two readings of the speed of a fan. If the first is higher, my random bit is a 0, otherwise, it is 1. Variances in air and voltage would cause the speed to change. Seeing as most PC's today can access the fan-speed data, it's basically a free random number generator. Free = very cheap

Not at all. I said the parallel processing abilities and consciousness of the human brain could not be replicated on a sequential Binary system. Your assertion was that the Learning mechanisms of NNs were nothing like the Brain, which is why they haven't given rise to consciousness. This isn't the case.
My conclusion is that it’s more than the ability to learn that is required.

Huh? It was your assertion that the Neuron was simple and trivial in comparison to the Silicon chip. The fact that other Neurons are required to function as memory simply puts it on a par with a single chip? I never said they could function alone, I said they could do a lot more than function as a switch. The other Neurons stored the values, so how's that any different to a silicon computer needing memory?

No. I am not fighting QM. Small distances being meaningless to measure doesn't mean they don't exist. We can't measure picometre with a centimetre rule, that doesn't mean it doesn't exist. The reason the distance is meaningless is because the very act of measuring it changes it by a degree greater than itself, therefore meaningless, not non existent.

I still contend that NN's are unlike the brain in capacity. Just as worm ganglion (early brains) are unlike human brains. I doubt you would claim that worms are sentient, but adding complexity to the ganglion they use, led to brains that did give rise to sentience. Similarly, NN's that aren't so narrowly limited, I believe are a key in giving rise to an artificial being with sentience.

Would most people assume that Windows XP can be run on a steam-powered system of gears ... it's mathematically provable that it could, but it's the complexity (and slowness) that is overwhelming. So, sure (barring the absolute necessity of quantum effects), YES, more cogs is all that was needed.

Heh ... I had a feeling you'd dispute "true" randomness with me. Technically, I suppose you're right. The output of a fan is completely dependant of air turbulence and voltage, both of which can theoretically be measured. But the practicality of measuring every atom of air in a normal room makes the randomness of the fan just as "true" as a quantum system. Quantum-based systems just have the advantage of not even being theoretically possible to measure.

That the universe isn't digital.
That a computer is digital.
That a digital system can't perfectly model an analogue one no matter how much precision you use.
You're counting electrons, which mean's you've dropped down to the sub-atomic level, so you need a model of the sub-atomic level now. It's not as simple as saying that's how many electrons there are.

But if you think you have calculated EXACTLY, ACCURATELY, PRECISE measurements why don't you work on that in software, as described. It's the only way to prove me wrong .
Quote:

No I'm assuming that it probably does. Creativity, Inspiration, any number of things that make up consciousness has a very indefinable quality, even to us. It makes sense that this could arise from something ultimately indefinable.

But then that's my assumption, what makes it less important, less worthy, less viable than your assumption that it's just a function of the brain as a Learning machine?

Okay, so you want evidence from me that your proposal won't work, yet you have given no evidence that it:
A) Will even turn on.
B) Is actually viable given modern technology, or even future technology.
C) Would even give rise to a conscious intelligence.

Your entire position is based on Assumption, assumption that silicon technology is capable of that which you think it is, assumption that Quantum effects within the brain don't have an effect on it's operation and the big underpinning which is the assumption that consciousness arises solely from Learning (or the ability to learn).

Strange evidence that your proposal CAN work, but duly noted .

I don't want to attack you as much as that may have come across (I’m tired, it’s 1:30am here), it's just when your point is based heavily on assumption you can't turn around and attack the assumptions of your opponent like that.

Quote:

Heh ... I had a feeling you'd dispute "true" randomness with me. Technically, I suppose you're right. The output of a fan is completely dependant of air turbulence and voltage, both of which can theoretically be measured. But the practicality of measuring every atom of air in a normal room makes the randomness of the fan just a "true" as a quantum system. Quantum systems just have the advantage of not even being theoretically possible to measure.

There's more to something being random than merely being impossible to predict, it also has to be statistically random. I believe the random thing started up by trying to build in a random element to the simulation (as that is all you believe quantum effects may have on the Brain, right?). Well if your not modelling exactly (i.e. using true random numbers) then you've got a simulation with an acceptable degree of precision.

Is a simulation with an acceptable degree of precision (i.e. error) as good as the real thing?

A large point you seem to be sticking to is that approximations are bad. I'm sure you would possibly attribute "some sense" of consciousness to dogs, maybe even a squirrel. Those brains are definitely not as complex as human brains. They are, in essence, approximations that still give rise to sentience.

Another issue is that the things that you believe MUST be approximated by finite systems, I can show do not HAVE TO be.

Quote:


That a computer is digital.
That a digital system can't perfectly model an analogue one no matter how much precision you use.
You're counting electrons, which mean's you've dropped down to the sub-atomic level, so you need a model of the sub-atomic level now. It's not as simple as saying that's how many electrons there are.


A normal neuron can generate a potential difference of about 70 millivolts. Even if we went nuts and assumed it was 150 mV, dividing that by one electron volt gives us a little less than 950 quadrillion (10^12) electrons. A 60-bit register could easily store this inflated count.

I see no need to "model subatomic behavior" to model a neuron accurately.
The number of neurotransmitters is guaranteed to be a much smaller value and is more likely the limiting factor in precision, but we'll figure that the number electrons is the necessary limit of precision.

As I understand it, the first question is whether the current will be generated or not. The neuron holds a threshhold which must be exceeded. This threshhold is going to be a voltage with less than a 60-bit number of electrons. No approximation needed so far. Next is the total voltage that gets generated - the "arithmetic," as you call it. Again, this is going to be a particular number of electrons which get motivated to pass - a number of finite precision. Finally, some neurotransmitters will be released and, again, this is a finite number.

But if you think you have calculated EXACTLY, ACCURATELY, PRECISE measurements why don't you work on that in software, as described. It's the only way to prove me wrong .

Quote:

Ohh... so, the discovery of quantum effects of unknown consequence is some sort of evidence that what I propose can't be done? Strange evidence, but duly noted.

No I'm assuming that it probably does. Creativity, Inspiration, any number of things that make up consciousness has a very indefinable quality, even to us. It makes sense that this could arise from something ultimately indefinable.


That was fairly rude, my apologies. But, you disputed me with something with no known consequence. It'd be like saying that the particular speed of light through organic matter is probably the reason that sentience cannot arise in machines. Sure, it's true about the speed of light, but the consequences aren't even close to being known.

Quote:


But then that's my assumption, what makes it less important, less worthy, less viable than your assumption that it's just a function of the brain as a Learning machine?


Kinda ... learning and high levels of intelligence, so far, are always found paired with sentient beings. Quantum effects can be produced in a lab within a quite non-sentient metal box.

Okay, so you want evidence from me that your proposal won't work, yet you have given no evidence that it:

A).. ok .. got me on that one. I haven't built it. Heck, I just designed it 2 days ago ...

B) Actually, I've given you a viable design in one of the above posts using current technology. It doesn't have any technical limitations, as far as I can tell, but I'm no Elec Engr. At worst though, building my design should just be larger than I propose.

C) Well, I suppose that's what the debate's about, eh.

Yes ... even man-made quantum memory banks can be constructed, if that's what's necessary.

Why expert systems? ... maybe b/c those are where the money's at, ever since the commercial success of MYCIN and PROSPECTOR, I'd suspect.

Well, that and the military works on the best stuff and, of course, keeps most of it classified. Like the one Navy AI program that actually does make impressive logical inferences and points out difficult-to-spot contradictions. Can't remember the name right now. Something like Naval Research Logic Analyzer. I think they even ran the Bible through it. And it made inferences like shephards (in some cases) must be God, etc.

Before we wander too long .. I'll post my "Revised Laws of Robotics," [based on Asimov's suggestions] to ensure that mankind won't end up as batteries

Feel free to critique!

Zeroth – Define Human, and harm (physical, psychic, consciousness, economic, not emotional), action, inaction, life-threatening, imminent, robot, laws, subject, appreciable, cause (directly, indirectly, through agents)

First - no robot may commit an act that has any appreciable probability of resulting in another robot not being subject to these same laws. [cannot build other robots that are morality-free]

Second – A robot may not through action or inaction allow any humans that are not directly in control of imminent harm to some other human(s) to be dealt life-threatening harm. [cannot be threatened to harm innocents]

Third - A robot may not cause life-threatening harm to a human being, except where such orders would conflict with higher Laws. [cannot kill anyone, except maybe terrorists]

Fourth - A robot may not through inaction allow more humans to come to harm than necessary, except where such orders would conflict with higher Laws. [must save as many as possible, instead of reaching deadlock in allowing inaction to sacrifice some]

Fifth - A robot may not harm a human being except where such orders would conflict with higher Laws. [cannot hurt anyone, but 2nd allows to save from terrorists]

Sixth - A robot may not deceive or manipulate a human being, except where such orders would conflict with higher Laws. [cannot lie]

Seventh - A robot must obey orders given it by human beings, except where such orders would conflict with higher Laws. [productivity]

Eighth - A robot must obey orders given it by superordinate robots, except where such orders would conflict with a higher-order Law [productivity]

Ninth - A robot must perform the duties for which it has been programmed, except where that would conflict with a higher-order law [productivity]

Tenth - A robot must protect its own existence as long as such protection does not conflict with higher Laws. [productivity]

Not exactly. Approximations aren't bad per se, but a Dogs Brain is not an approximation or a simulation of the Human Brain. My point is that a simulation is not the real thing; it's a simulation of the real thing, just as my earlier mentioned trip to Jupiter in Celestia isn't a real trip to Jupiter, but a simulation of one.

Well, the issue of "true accuracy" isn't a requirement I believe is necessary. I don't think 60-bit precision is necessary, either. I was just pointing out that exact precision can be calculated on a digital system, theoretically.

Ahh ... so you're starting to see the possibility ... eh ... it's a start Memory space is cheap .. so whether it's 10 or 10,000 signals, they still all only require an address (and maybe a weighting). Simplest way to model the system is to clock your system X times (X = number of connections) to send out your "electronic neurotransmitters," and then allow neurons to check for new inputs on the Xth clock. Update your neuron on that last clock. Check if it received enough "neurotransmitters" to exceed whatever it's firing threshhold function is and then do it all again. (Again, I've neglected the re-wiring procedures that would be needed.)

On a side note, in the end, how do you know exactly, that everything you experience and even everything that you DO isn't a fancy simulation that and if even if you KNEW that we were elaborate simulations of some sort, would you then deny yourself consciousness/sentience/self-awareness???

It's not quite that simple. One way the inputs are weighted is on the shape of the Dendrites themselves, which means that no two Neurons will react to the same input signals in the same way. I'm also unsure how this system would take into account the temporal weighting I mentioned earlier.

I'm still not convinced that that system could model the vast time dependent interactions of the Neurons though.

But before we get too over excited about the abilities of modern micro electronics I'd like you to consider that the brain is one of the most densely connected network systems in the known universe.
Somewhat un-intuitively, the more intelligent someone is, the less active the brain will be compared to the brain of someone less intelligent performing the same task.

We're talking too different things here.
How does the robot know whose side to step in on?

The point is if you start putting in provisos like:
You can't hurt Humans, unless they're terrorists.
Then that's a loop hole. What happens if for whatever reason the Robot sees someone as a Terrorist, they have a toy gun or something?

This actually happened with a Soldier shooting a kid in Northern Ireland because all he saw was the end of a realistic toy gun sticking out a window.

If we're going to leave robots open to making these kinds of mistakes because of loop holes introduced by obfustication of the laws then there is absolutely no point in having the laws in the first place.

I assume you've see the Will Smith film version of I, Robot (not much to do with Asimov at the end of the day, but oh well). Heaping more rules (and really even adding rules of interpretation that are anything but literal) would lead to both the actions of Sonny and the central computer (the name of which eludes me at the moment).

I personally think Asimov’s laws of Robotics are about as perfect as they can be, they're like the Ten Commandments, simple direct and too the point, everyone knows where they stand. Though one of your aforementioned Robotics companies would probably want to put a no stealing law in there .

If we were to ever create an intelligent race, such as Robots, we may want to revise laws such as Asimov’s that we may imbed at a later date, but I think that revision would take the form of removal, rather than anything else.

When they’ve taken away more of his brain’s non-autonomic function than the rest can make up for.

I’d be willing to bet no matter how good Robo Doe mirrors John Doe’s past personality if you’d look into his/it’s eyes, they’d be dead.

It would be like watching a recording of someone who died; do we prescribe the image on the screen with sentient? I’ve never heard it argued that we do.

Totally possible. Though it wouldn’t be the first time we’ve created a technology and even used it without really knowing how it worked. If we created a biological brain unique to any that has existed, through genetic engineering of Neurons and building them up, and the brain gained sentient we still created it, yet we still don’t know how it works.

Actually, following Asimov's laws would probably MANDATE the end of human civilization.

Premise: Human conflict is inevitable.
Premise: Human conflict causes harm to humans.
Premise: Humans would be harmed if they must be physically restrained from entering conflicts.
Premise: Sleep is harmless.

Therefore, if a robot is ordered to not allow humans to come to harm through inaction (and this rule supercedes all others), then the only logical development is probably to anesthetize us all and keep us asleep until we die.

Maybe loophole is the wrong term, but the above scenario is a pretty serious deficiency. I attempt to cover this deficiency in my revised lasws by adding an unconventional meaning of harm in my Zeroeth law (relating to consciousness [as in awake, not referring to sentience]). I think I'll add something to the effect as a new law after the thrid though ...

Of course we can see the "strings" if it's animitronic and we open it up. What if you open it up and still can't explain it's intelligent behavior ... *that* is the question at hand.

That's a different question, but if we have a definable originator of the actions it is reasonable to assume that the puppetry is merely beyond our understanding.

A robot must obey orders given it by superordinate robots, except where such orders would conflict with a higher-order Law
Law Three
A robot must protect the existence of a superordinate robot as long as such protection does not conflict with a higher-order Law
A robot must protect its own existence as long as such protection does not conflict with a higher-order Law
Law Four
A robot must perform the duties for which it has been programmed, except where that would conflict with a higher-order law

The Procreation Law
A robot may not take any part in the design or manufacture of a robot unless the new robot's actions are subject to the Laws of Robotics

Understanding that to harm or injure humanity would mean permanently putting people to sleep.

Well, those aren't strictly Asimov's laws ... the one's you quoted include additions from some Roger Clark guy. But, they are surprisingly similar to mine, so he must be a genius ...

Dang, we're good great minds and all ...

Yeah, I got that , the important one I think is the zero law, and that was added by Asimov himself, after the fact.

I think a "procreation" type law actually is a necessity to any list of laws. What good are the laws if they only apply to the first generation of robots? The 2nd generation just gets to be the ones that plug us into the Matrix.
