Look For AI, Not Aliens

krou writes "Writing in Acta Astronautica, Seti astronomer Seth Shostak argues that we should be looking for 'sentient machines' rather than biological life. In an interview with the BBC, he said, 'If you look at the timescales for the development of technology, at some point you invent radio and then you go on the air and then we have a chance of finding you. But within a few hundred years of inventing radio — at least if we're any example — you invent thinking machines; we're probably going to do that in this century. So you've invented your successors and only for a few hundred years are you... a "biological" intelligence.' As a result, he says 'we could spend at least a few percent of our time... looking in the directions that are maybe not the most attractive in terms of biological intelligence but maybe where sentient machines are hanging out.'"

Basicly this means, that the realness of emulation is limited on how we emulate biologically solved actions.

      Useful data to consider when we get to the matter of simulating neural networks is how much progress we have made in simulating simple natural networks which we have already completely characterized structurally.

      We have one such network in the model organism Caenorhabditis elegans (a tiny worm). After many years of work its nervous system has been completely mapped: it contains 302 neurons, 6393 chemical synapses, 890 gap junctions, and 1410 neuromuscular junctions.

      So we must have simulations of C. elegans little brain running, right?

      Nope, not even close. We are still in the early stages of simply characterizing the behavior of these 302 neurons. It will only be after many more years of research that we would understand what it does well enough to make a reasonable simulation. Forget IRM (I think this is a different acronym for MRI), being able to dissect the entire nervous system neuron by neuron and probe it directly at every point is not enough (yet) to describe what it does.

      Now imagine trying this on a neural network 50 million times larger that you can't dissect at will, and which has correspondingly more complex behaviors.

      Still should be possible in principle - but the level of difficulty is immensely higher than "singularity" theorists would have you believe.

      we achieve parallel tasks easily, if the task can be broken down in separate individual serial functions, especially if you think about the GPU doing stuff (sending pixels to the screen or other 3d effects) which can be async because we dont have to wait for the result in the CPU - even without using the GPU as secondary processing unit. however if you want to use the parallel computed data, you still have to wait somewhere for it to be unified.

      now the brain does a similar job, in sending functions like motoric functions to your peripheral organs, like muscles and of course in retrieving data from peripheral organs, like your eyes. it even does that in saving pre arranged functions in your minor brain, like playing chords on a piano.
      it even sends data to your peripheral organs before you know it (studies have shown, that with electrical impulses, the wish to press a button can be "foretold" by capturing the signal).

      however, despite this, the brain does not really work with coded binary signals like computers do. everything is done by chemical transmitters, electrical impulses are only diffuse and carry signals to the periphery of neurons, where the change of electrical charge triggers the release of transmitters. how everything interacts and builds up a network of working "thought" depends on the physical wiring of the neurons, and a lot of impulses happen at the same time, resulting in a neuronal network capable of performing many tasks at once with the same hardware.

      a lot of systems interact, some of them slow, other of them very fast, understanding all the interactions proves somewhat difficult.

      i might be wrong, and all i say, thats what i was told by books and professors, especially those, who work in AI explained; there is even a problem in the basic understanding of parallel computation. all our signals are at the time being coded in charges which represent one or zero added together representing numbers, which might be signals or simply data. all our programming languages rely on this fact, even if we created a lot of systems which enable us to split jobs in multiple jobs.

      it also comes down to the level how data is stored. we store data serially with the same coding, but the brain rewires itself to represent learned data. its not simply numbers in a row. its more like patterns.

      describing our surroundings in analytical manner and storing this information needs a human component of identifying which data has to be stored or represented, and it still is saved as numbers. emulating a virtual network of neuronal mechanisms allow us to simulate the learning behaviour of a human brain, but it is still only one aspect of the brain we try to master. we have to feed it with what to learn and how to do it.

      we are still far away from creating a self driven thinking machine, and even if we do create one with the technologies we develop in computing, we still will emulate it with our way of storing and processing data only. and we might encounter physical barriers we cannot break, resulting in much slower speed.

The brain's function is to find the probability of survival. The highest the probability of survival is, the more the brain instructs the body to stay and take advantage of the situation; the lowest the probability is, the more the brain instructs the body to run away.

Nowadays, we don't do anything about spam, because the computer recognizes it with almost 100% efficiency, thanks to the statistical methods applied to them.

However, they are clearly better suited for space exploration: They don't need air, they don't need water, they can withstand higher accelerations, they don't suffer under weightlessness, they don't get bored (OK, the latter might be different for a true AI, but then, you could simply put it to sleep in situation where non-AI systems work well, and only wake it up for situations where it is needed). To send humans in space, you need complex life-support systems. To send machines into space you just need an energy source.

      The point is that life forms, including humans, evolved to live in an ecosystem. If you want to leave that ecosystem, you basically have to carry an imitation around with you. While this is certainly possible, it's wasteful. Machines OTOH don't need an ecosystem.

Then he manages to write a convincing dialogue written by one of these machines! (You try writing dialogue of something incomparably smarter than any human; I would have trouble writing dialogue from my dog).

    Anyway, he posits that Super-intelligences might eventually migrate to the vicinity of black holes not for the time dilation from their gravity wells but from the almost infinite heat sink they could provide. You see, he figured that any unit of computation will require a certain minimum amount of energy and, well, that energy will eventually be converted to heat (as every dual core laptop user knows). So, in order to get the most amount of thinking done (I mean what's the purpose of having a giant brain if you can't run it all out?), they'd want to be in close orbit around a black hole because they could dump all their excess heat down it. (As a side note, it would be almost trivially easy to generate power; by exploiting the gravitational potential, like a waterfall, you could get a very high proportion of an objects rest mass converted into energy).

    S. Lem wrote his story before (I think) there were some theoretical analyses done of minimum energy requirements for computation; I think the theorists figured out that there are no minimum requirements IF you are willing to wait an arbitrarily long time for the result. Also there may have been some studies involving reversible computing that says zero energy is required IF you never erase your memory. So I think his story is correct in deciding that black holes were the place for deep thinkers. This is supported by a Scientific American article asks, "what would the ultimate computer look like?". Their answer (due to the data density, energy requirements and heat dispersion) was: a black hole!

    Finally, I've heard there's some way of actually using a black hole as a computing device (and possibly the most powerful one theoretically possible). I think it has something to do with the ergosphere of a spinning black hole; this concept was used in a science fiction story by Greg Bear(?) in "Eater". Guess what it liked eating? Information!

Manufactured systems have a life cycle that is many orders of magnitude less efficient than bio systems. They use exotic materials in industrial processes that are energy intensive. Imagine being a creature that relies on large amounts of Indium, Gallium and Arsenic, megawatts of energy and so many exotic chemicals to repair one's self and to reproduce. Our current technology just isn't near close enough for an explosion of AI machines.

One important consequence of this increase in experiential speed is that subjective distance also grows by several million-fold. A trip to the moon, which might take only 100 human subjective hours, would take 55 thousand years of subjective time for intelligence operating at 5 million times human intelligence. By the time any intelligence made it just to the moon and back, the intelligence it departed from may have evolved to an unrecognizable state.

Interpretation of the data being carried is not required to infer that data is, in fact, being carried. All you need for that is to observe the nature of the signal.

      The point is that reproduction is fundamentally a different process from construction. Perhaps a way to see this is to consider that nowhere in the DNA is a blueprint for a body. The majority of the function of DNA can be reduced to coding for proteins. This basically means that a strand of DNA within a cell codes for a set of proteins to be produced which alter the behavior of that cell. Bodies are not built based upon any sort of blueprint (like a machine is built), but instead by local components operating on local rules.

      Complex shapes in bodies are grown by different clumps of cells growing faster than other clumps of cells. Different tissues are produced by turning on and off different genes.

      This is fundamentally different from a construction process because the end product is not contained in the DNA. Instead, the end product is a result of complex interactions between the DNA, the cell, and the environment in which the cell resides. This means, for instance, that some of the same bits of DNA that are used to build a hand are also used to build a foot. Some of the same bits to build parts of an ear are also used to build parts of the jaw.

      This is to be contrasted with a constructed machine, where if we imagine a human-like robot (two legs, two arms, head), I might decide to swap out the arms for a different set, give it longer or shorter legs, or remove the legs entirely for a set of Johnny 5 treads. You can't do this sort of thing with a biological organism.

      And this difference makes for one extremely crucial distinction between the two: machines are wholly deterministic entities, where you start with a blueprint and, up to small manufacturing errors, know exactly what you're going to get out the other end. Life forms are a combination of determinism and randomness, and you never know exactly what you're going to get once you start a life form growing. This randomness, as it turns out, is an exceedingly useful quality that allows us to be creative, to be inventive, and to survive where we otherwise might not.

      As a final note on reproduction, it turns out that biological organisms are only limited by the food/resource capacity of their environment. They always expand to consume everything that can be consumed, and do so remarkably rapidly. The issue here is that exponential growth is a tremendous thing, and any time an organism is using fewer resources than it otherwise could, it (or some other life form) rapidly grows to fill that void.

      Sure, it may look slow on the level of an individual person, where the generation times may be 20-30 years, but it doesn't take long to turn a few million people into a few billion, once they can produce the resources to sustain them.

      Machines, by contrast, have the problem that production is linear: in order to produce more machines, you first have to produce the capacity to produce more machines, which takes time. People simply reproduce.

      Well aware of it. My position on what engenders belief in religion (as opposed to implementation and practice as a mechanism for control) may be found here. You'll note intelligence isn't even mentioned.

      I'm high IQ myself, well educated, and a better critical thinker than many of my acquaintances.

      Ok, so... are you religious? If so, why? Do you think you have an immortal "soul"? What critical thinking process led to that conclusion, if that's what you think? Or, do you think that nature somehow requires a creator? Again, what critical thinking process led you there? By all means, let's talk about it. Perhaps I will have some observations that you can pick apart, or contrariwise, find useful.

      I'm open to talk further if you want, but I'm not sure what it would accomplish.

      If you're *actually* open, it could accomplish quite a lot. I'm open the other way; show me some solid evidence, that's all.

      my experience of my wife is not primarily objective and empirical

      No? What other kind of experience is there? Your thoughts are really happening, are they not? Hormone dumps as well? Memories actually recalled? Fun, sure, but where is the non-objective or non-empirical here?

      We're talking past each other a little here.

      What I meant to highlight is the difference between the inner and outer life. Outwardly, one has senses of sight, touch, hearing, and so on, with their corresponding objective, empirical measurables.

      But there is also an inward life of relationships, philosophy, emotions, decisive will, ethics, reason, and indeed spirituality. This is the domain of the subjective, not being "out there" in common space between us, but being within us. (In this sense, however, the term "subjective" makes no claim to universality or lack thereof. Something can be both subjective and universal.)

      Does the subjective have a material mechanism? Certainly. Is it limited to that material mechanism? I'm not sure, personally, but that's not terribly relevant at this point. The point at hand is that it's possible to concentrate too heavily on the material, objective measurables when dealing with the inner life. As Einstein was known to say (though it predates Einstein), "Not everything that can be counted counts, and not everything that counts can be counted."

      I submit to you (also respectfully btw, thanks for engaging) that just because you don't know how to describe something in simple terms, that said thing is not mundane in nature. For instance, one might well not know what's going on inside a radio, but that doesn't make the experience transcendent; it's still just as mundane as dropping a rock on the ground. No magic at all. You might think like crazy about it, wondering what is going on; you might experience hormone dumps, frightened by the voices you hear coming from the "magic box"; but the box is, in fact, not magic. What I'm getting at here is that your experience is not what makes something mundane, or not; nor is your understanding. It is what it is. And all the "is" we know of to date... you guessed it. Mundane.

      Yes, it's good to remember our humility in these matters. There is a lot we don't know. :-)

      Also just because something is mundane doesn't mean there isn't also mystery in it. Sir Isaac Newton was mystified by the apple dropping to the ground, much like your rock. And however far you dig, there always seems to be another layer, which is mysterious in itself. But I'm sidestepping the issue.

      You're assuming that I'm lumping together what has no current explainable mechanism and calling that a soul, and assuming it to be a-material. That's a rather materialist way of presenting a fault in my argument. Rather like a hammer thinking everything is a nail.

      See above. The inner life, what I would call the "soul" (but different than the "spirit" -- see below) has material mechanism. I don't disagree with you.

      But note that if you're going to argue emergence, then you cannot also argue complete reducibility to elements, as many materialists tend to.


      Religion makes claims of truth that don't share an identical domain with science, and therefore need not be mutually exclusive.

      To date, we have discovered exactly one domain. Mundane reality. Religion is no more than an exercise of storytelling; there's no difference between a story of Zeus and one of Spongebob. Telling a story doesn't validate its content, any more than any flight of imagination actualizes the concepts involved. Now - if you disagree and would like to engage on the level of what you think the separate domain is, I'd be pleased to discuss it with you.

      I didn't say they don't overlap.

      I'm interested in why you're such a militant atheist. Why did you become so?

      In my 54 years, I have seen nothing - at all - that suggests to me that there is a god or gods. This experience is exactly the same as my experience with astrology, unicorns, talking teapots, crystalomancy, and so forth. I have encountered absolutely no reason to believe.

      On the other hand, I have learned a great deal about people's abilities to convince themselves of the most absurd propositions. Depth of faith is clearly not an indicator of truth: it constantly leads people into the ridiculous and the contradictory. The number of people who believe something is also no indicator of truth. Actual approaches to truth within the bounds of our understanding - the presently incontrovertible - are self evident, in that they may be inductively validated by objective fact, testing for falsifiability, and our understanding rigorously adjusted as we learn more. This is a mode of consideration that religion fails miserably. Yet it is, as far as I know, the only one that actually works.

      In addition, I find that religion - Christianity in particular - wraps itself around the most odious and hypocritical outlooks. For instance, you are happy to think your god is a good guy for futzing about with the fertility of your circle, while at the same time, this supposedly omnipotent, omniscient entity won't be bothered with moderating the slaughter in Sudan (just to name one of many such venues.)

      That's why I am atheist; the reason I am vocal about it is that the religious are interfering with my life on many levels. From adherents flying into skyscrapers to preventing me from buying beer on Sunday to intimating that my honor an character depend upon placing my hand on a book of mythology in a court of law to trying to tell my friends they can't marry, I find religion to be both constantly in my face to an unacceptable degree, and also, an anti-science force with literally centuries of appalling abuses on record.

      Do you think that it's provable that God doesn't exist?

      No. Nor is it my role, as someone who lacks belief, to try and prove a negative. What you're asking is precisely equivalent to asking if I can prove there is no talking teapot in orbit around the sun, or to prove that earthquakes aren't actually caused by invisible pink unicorns that run upside down along the fault lines. I can't prove those things either; that doesn't, however, serve in *any* way to somehow vouch for the actuality of the matters in question.

      But: in fact, I can turn to my experience of reality and give you this answer: While I can't prove a negative, I can evaluate the probability based upon my life experience. And I find that the probability is about as low as it can be; or to put it another way, my confidence is extremely high that there is no god or gods, and that the entire religious experience (outside of intentional scamming) is one of self-delusion.

      These aren't meant to be proofs of God's existence.

      Good; because those stories don't serve the purpose. I'm not very interested in how you interpret mundane events. The fact that they are mundane disqualifies them from serving as evidence for a god or gods. Mundane stuff happens. People get pregnant; congratulations are issued for this and that, and sometimes they are the result of misinformation or guesses. The odds favor all of us encountering the unusual from time to time. Taking such events as evidence for supernatural power is really uncalled for. So what it boils down to is you're telling me mundane stuff happens. Such stories don't serve to make your case, or even to back it up.

      In any case, this isn't what I asked you for; I asked you what critical thinking process led you to your position. You said you were a person with a high IQ, as well as a critical thinker. That's why I asked just that w

Our ability to sense with this faculty is affected by our internal state and disposition. It's like as if it's a sort of internal tuning fork that can get all crudded up, but when it's clean, resonance can be induced in it, and it can carry signal. If you have experience of this faculty, what I've been saying would resonate with you.

Human beings are more than just our faculty of reason, and the usefulness of reason has its limits. Indeed, many people when presented with stark evidence of something will still reject it, and vice versa, because we are not entirely rational beings. I've been honestly trying to describe something rather difficult to put in words, and to share of my experiences with you. You're asking for apples when all I've got available is oranges because of how it works--the spiritual life is manifested inwardly. I really don't care for teleological and ontological arguments, because even if the point holds, you're not left with a description of God or the interior life that really does it justice, but it seems that's the sort of argument you want just so you can bat it down as hard as you can. It's hardly charitable or sociable to resort to name calling and vitriol just because you can't relate to it. We're at impasse. Now we go our separate ways.

A graphic representation of data abstracted from banks of every computer in the human system. Unthinkable complexity.
