The Singularity and Abundance
Indeed that’s true (the Singularity is all about abundance, or The Big Rock Candy Mountain). I don’t believe it will be accomplished, of course. I’m not convinced that solar cells or other such technology will ever become cheap enough/efficient enough to scale to the point of providing essentially free energy.
On Mind uploading and consciousness
Among the many problems with this idea of mind “uploading:”
Well, if “nobody really knows what the mind is”, as you correctly state, then how can you be so certain that it cannot be copied or uploaded?
It seems to me your position is no more valid than those who claim that it can. If nobody really knows what the mind is, then it is still an open question and your assertions are no better than anyone else’s; and, as with your biological chauvinism, is merely based on emotional preference.
For myself, I do not see why there is any reason to believe there is anything mystical or nonmaterial about the mind, whatever it is. If there is, then I think the onus is on those who believe this is the case to show it. However, if I knock you in the head hard enough, you go unconscious, or even die. What happens to your mind then? Where does it go?
Whether unconscious or dead, you don’t have your mind anymore, either temporarily or permanently. That would seem to be a pretty good indicator that the mind, whatever it is, is very closely related to the brain.
So, if it is true, as seems likely to me, that the mind is based on processes and information in the brain, then it is based on something physical, which means that, in principle, it is treatable as other physical objects: movable, copyable, storable, modifiable, improvable. Now one can debate whether this is practicable in the real world any time soon with foreseeable technology, (due to the extreme complexity of the brain), but that is a different question.
Thanks for the detailed and thoughtful reply. I delayed responding because I couldn’t decide on how much to respond to and for how long. Finally I decided to just respond to what strikes me as the main point.You seem to be contending, (correct me if I am wrong), that no matter how advanced a machine becomes, it will always be mimicking consciousness or sentience, that it will never really attain these characteristics.
Unless you have some criteria, which I haven’t seen, which, if fulfilled by a computer, robot, android, whatever, you would then agree that it was conscious or sentient. If so, I would be interested in hearing them. I’m sure they would be thought provoking. But if you don’t have any such criteria, then there can really be no further discussion. You have predecided the issue and there is really no more to be said.
I would only wonder though how you would respond if someone were to make the claim that you are not really conscious or sentient, but are merely mimicking having these traits. (I am not making this claim, by the way.) But if I did, how would you answer? Bearing in mind that anything you say or do could be said or done by a sufficiently advanced machine that, by your view, would only be giving the appearance of having these characteristics.
I have often wondered whether John Searle had been asked this question, and if so, and if he answered, what his answer was. Now I have the chance to ask someone who, if my understanding is correct, seems to have a similar view. I’m not going to pass it up.
Thanks for the response. It helped me to clarify my views on some things.

Consciousness, the irrational and creativity
Another Cool Hand Luke moment (“what we’ve got here, is failure, to communicate.”), from my talks with the Singularitarians.
@David and others:
I think we need to clarify what Mr. Tyson meant by “irrational.”
I believe “irrational,” in the context he was using the word, means:
1. Not the product of rigid/linear/billiard ball type causation
2. Not articulable/cognizable through the mechanism of rules (whether strict or fuzzy)
3. Not fully understood or arguably understandable
I think it’s an unfortunate word choice, because the obvious connotations are that the “irrational” is “bad,” or “suboptimal,” or whatever.
I think it would be better to talk about the undefined/undefinable, which is to say, humans (and, I think, all sentient, living creatures capable of complex thought) do not just do as they are told,
Which is what machines do
They think up things for themselves, and those things are not necessarily determined by prior requirements, confined within existing rule sets, predictable, or capable of being mimicked through the introduction of “randomness” or “probabilistic” mimicry of improvisation: the universe of possible options may be finite but is large enough, in practice. It won’t do to have machine just pick from within some predefined subset, or I suppose, explore, define a subset and pick, randomly or through application of a probabilistic algorithm.
That’s not creativity because there is no purpose/intention behind it; it’s just chance.
@Ryan
What you’re describing may work well enough for some soulless drek like a Katy Perry song, but again, it’s not creativity, it’s aping creativity. An “algorithm” that introduces randomness into a composition simulation, is just a machine following instructions; it isn’t creating anything itself, because
1. It is just executing instructions programmed into it by somebody else,
2. It has no concept of what the instructions are for
3. It has thus not decided to do this and not that, for any reasons other than those programmed into it by its controller
The end result may look like a musical composition (to the extent a Katy Perry song can be described that way), but it’s really just a copy of other compositions (either a direct copy/mashup/distortion of music composed by humans before, for their own reasons, or a derived copy, produced by executing rules that are themselves defined by abstracting away various structural aspects of previous compositions [again, compositions created by people for their own reasons, which were effective to the degree that people responded to them (as individuals and collectively, subjectively, but as people)]
You say a set of such “compositions” can be made then run through a filtering algorithm, which will determine their “quality” and rank them.
But how would such an algorithm judge and rank quality? To the extent it is possible to do that programatically, the machine would just be applying, again, rules defined by people in an attempt to articulate what it is about music that makes it effective (I suppose you would say “elicit the desired response”).
The machine doesn’t know what is better or worse, subjectively, it just applies the rules it’s been told to apply and produces a list.
This is all just aping, and bad aping at that.
Of course, by definition, there is no room for anything new here at all, just more or less successful applications of the existing rule sets (anything new introduced randomly or as the product of some probabilistic algorithm would be very hard to judge through such a mechanism, and, in any case
Would be missing the point
Because there would be nothing real behind it, which is to say, it would not express anything, because its creator would have no expressive intention or even awareness of what is being created; thus, the product might be pleasant in some way, but it would be meaningless.
It’s like taking a digital picture of a yellow flower and running it through the Van Gogh filter in Photoshop; the product might look like a Van Gogh, but it’s not, it’s a mechanical forgery.
@Evan Dawson
We both reject the use of the word “irrational” here, as commonly understood, to describe creativity, but I think your essential statements
1. I think of creativity as the creation of knowledge in the absence of conscious reasoning.
2. while the unpredictability of creativity comes from fact that the sub-conscious part of the mind plays an essential role in it.
Beg questions.:
1. Is everything created a form of “knowledge,” and if so, how?
I think this is a reductionist denial of the aesthetic aspects of experience. I mean, in what way is Mozart’s Escape from the Seraglio “knowledge”? The beautiful exists as well as the good and the true, right?
2. Wouldn’t it be more precise to say that the creative process is hybridized between the application of conscious reasoning techniques (following, for example, various rules of composition established over time by people because they have been proven, like the structure of a symphony), and inspiration (which is not “rational” in that it does not follow necessarily from any cognizable rules or principles)
3. If so, aren’t you just defining away the problem by saying that inspiration (the non/extra/ir-rational) part of the creative process comes from the “sub-conscious”; I mean, do we really know where it comes from? Or is the “sub-conscious” a kind of grab bag for whatever we don’t understand about the workings of the mind? It doesn’t explain anything here (inspiration is irrational in the sense that it is not the product of conscious reasoning, thus it must be the product of some sub or un-conscious reasoning)
The ancients thought of creativity as the gift of the muses (divine entities who spoke through them); people in creative flow states often describe themselves as being possessed (anybody who has ever experienced this will tell you that ideas, words, images, take form or thrust themselves on you, as though something with its own life were giving rise to them; call this irrational, sub-un-conscious, whatever, nobody has explained it, except to explain it away by assigning it various labels).
You are certainly right to say that the results cannot be meaningfully replicated through randomness.
@Robert Mason
I agree with your idea of sentient, intelligent creatures having goal orientation, which is what I mean by volitional intelligence.
They want various things, decide among their wants and then act to fulfill them. Their genetic makeup (however it was formed), I think, largely defines those wants and provides the structure that tends to regulate their intensity (in a probabilistic, not strictly deterministic way; which is to say, I may want to drink water, because my genetic code is structured to signal me the body needs water, but I can choose to forego acting to satisfy that want, for whatever reasons).
Machines don’t know anything or want anything, they just do as they’re told.
(it’s true, the genetic code informs what we want, why we want it, defines our basic capacities to fulfill wants, and the limitations of those capacities, guides our choices, probabilistically, but it doesn’t determine them.
We take the form described by our genes, with the abilities and restrictions, rough preferences and responses, inherent in that form, but our actions are still chosen, we are not puppets of our genetic programming. [You cannot help what you want or how you feel, you are only responsible for what you do])
@Bill Sams
I am always addressing your argument, but briefly:
Describing the constituent parts of a thing does not define away its existence as a whole; being able to identify various physical structures of a brain does not, in itself, reduce the brain to those physical structures or the mind that (I argue) operates through the brain (the whole can be more than the parts, or some essential thing about the whole can be completely elusive when investigating the physical parts).
If you really believe that life is just a complex set of chemical and electrical reactions that, over time, have been spontaneously organized such that they now have the appearance of what we call conscious intelligence, reducing people and animals to organic equivalents of advanced computing machines,
Well,
Do you talk to you wife like that? I wonder. I asked a colleague of mine, who thinks just like you, that once, and he didn’t really have an answer. My point is, why would you care about people or animals any more than you do about machines or rocks if you think there is no fundamental difference between them, and if you don’t,
Why not just say that?
On a Proof that Friendly AGI is Impossible
In response to much screaming and moaning about the prospect of someone developing a logical proof that “friendly” AGI (Advanced General Intelligence) is impossible:
A proof that friendly AGI is impossible, would not make friendly AGI impossible, it would simply demonstrate that it is impossible; the proof would be a step forward in the sense that it would tell us something we don’t know… which would be, I’d say, rather important.
Some kind suggestions from our friend to the Singularitarians
Note: Many of these people are the kind who rooted for Arnold in the first Terminator, so they can be difficult to reach.
My friend tried here, though, by way of advising them on how to talk to a fearful public about the future:
You could just play clips from the Jetsons.
What the general public (or nonscientists, at any rate) wish Scientists understood.
The passions
From correspondence between a friend and the Singularitarians, on the question of life, non-life and Deutsch’s Computation reductionism
“If we cannot really know [if machines are alive], then we can’t assume that they aren’t alive any more easily than we can assume they are sentient. But how can we act without assumption of one or the other and still proceed?”
The burden of proof here is on the machines, you could say, and it should be a high burden. I’ve seen no evidence of humans having created any kind of mechanical life, let alone mechanical life having the potential to become superhuman in intelligence. It could be that we can’t do that, that all we can ever do is create really fast machines with a lot of memory, and maybe that’s fine, maybe that’s better.
“If you don’t know if [Shrodinger’s] cat is dead or alive, it seems to me you still have limited options as to how you can proceed. What is better – to assume that it’s more likely the cat is dead and light the box on fire, or to assume it’s more likely alive and open the box so you can at least check before doing something destructive?”
“The question comes down to one of greater harm – which has more dire consequences not just for humans, but for all life? That we assume machines are incapable of reaching a sentient status and continuing to treat them like machines (in other words, assume they can’t possibly be slaves, potentially enslaving something sentient) or to assume that they could be sentient and do everything in our power to figure it out before we get to the point of doing something destructive?”
For all of that, of course I think we should monitor it closely and not do anything avoidable that is destructive. But why would we want to create machines that are alive, let alone a synthetic superintelligence?
Deutsch and “Artificial Intelligence”
http://www.aeonmagazine.com/being-human/david-deutsch-artificial-intelligence/
I also don’t accept the “Universality of Computation.”
Sorry. I don’t think everything can be reduced to calculation, information retrieval, processing. I do think there is a qualitative difference, further, between life and non-life (which would be “racist” as the author says, though he never says that something “racist” is therefore “not true”; I suppose we are all simply supposed to know this, since “racist” things are, by definition, “bad” and “bad” things can not be “true”.)
Nonsense.
A machine that fools you into thinking it’s not a machine is still a machine. You’ve just been fooled. The Turing test, for all of Turing’s obvious genius and accomplishments, is silly; more importantly, it’s epistemic, not physical/ontologic (it is a statement about conclusions we as humans have come to about the identity of a thing, our knowledge, or seeming knowledge, of that identity, not the identity itself.)
You can say whatever you’d like, but thinking something is alive or human or conscious or whatever does not make it so. I suppose it is fairer to say we simply cannot know, ultimately, whether something is alive in the same way that we are ourselves alive (conscious, sentient, however you’d like to describe it); saying, because we cannot really know, and the thing seems to be alive (sentient, conscious whatever) therefore it is, or may as well be, strikes me as wrong.
(Similarly, you may not know whether or not the cat in the box is dead or alive, but it is either dead or alive, not both, or neither; you simply don’t know. That is to say, it has properties in itself independent of your understanding or observation. A person is alive, sentient, intelligent, conscious, however you want to describe it in himself, not because you think he is.)
I simply do not accept the reductionist idea that life is just non-life that can compute and act with apparent volition, and that the only difference between a person and a software program is computing power and clever enough coding. (I also think it a monstrous idea; but that’s a moral/aesthetic judgment, not an argument against the validity of the concept, so I’ll leave it be).
What is it that drives your computations? (what makes a person want to go left rather than right, decide to write an essay rather than go skiing, etc.) Only living things have desire (as one of their characteristics), volition, drive; these things cannot be reduced to the product of “computation” however complex; they are qualitatively different from that.
Life is not just problem solving (something makes the living creature [not “entity;” a cat or a person is not a rock, a corporation or an iPad] decide to solve or attempt to solve one problem and not some other problem, experience something, abandon something else, etc.
A Letter from a friend to the Singularitarians
Good day.
I would describe myself as a qualified technology enthusiast (which is to say, someone excited about certain intermediate term technological possibilities [regenerative medicine, genomics, robotics, etc.], while skeptical about others [AI, the singularity, the Internet as it has evolved {post Web 2.0}, the surveillance state, etc.]).
So I’m neither a Luddite nor an extropian. I have all of the rectangles (Plasma, LCD, Mac Pro [with dual widescreens!] MacBook Pro, iPad, iPhone, iPod, etc.), and I’ve been online one way or another since the BBS days, but I don’t watch commercial television; I don’t post on Facebook, Tweet, pass around YouTube clips, or otherwise spend my days playing with my telephone.
I also don’t believe that the Singularity will bring about abundance, the withering away of the state, or the peaceful ascension of humans into physical immortality (as indefinitely young post-humans) (most of that would be just fine, I just don’t think any of it will happen, not all at once, and if at all, not for a long time).
Technology is used by people (who seem intent on reducing it to its most moronic or destructive possible applications, like the blubbery infantile post humans chattering away at each other from their motorized chairs in Wall-E); I don’t believe people become magically transformed from the vapid, annoying, myopic, grasping clods they tend to be as individuals into some kind of wise superhuman force by stacking them on top of each other either (whether you call that stacking the market or democracy or state or metastate) (so I’m not receptive to arguments about market process [unhindered, of course, by the State] just solving all of our problems for us) I’m not anti-market (I was an Austrian!), I just don’t sacrifice to the Market God, just as I’m not anti-Machine, but believe:
The machines were created to serve us, not replace us.
As a lifelong anti-Marxist, I never believed in the labor theory of value (and think the closest thing we can get to a social ideal would be having the machines do all of the [non-creative] work, freeing humans to do more interesting things with their time; rather like Athens or the Roman Republic (with machines standing in for the slaves).
Until recently, nobody really cared about “jobs” (work was for slaves), what they cared about was wealth.
A Note on Population
Any discussion about economics or the environment that ignores population growth is a waste of time. The trillions spent and technology applied thus far to the problem (of what is called global development) have all too often worsened it by making possible a population explosion that could never have happened in their absence.
It won’t do either to assume that population will stabilize in the “developing” world as it has in the “developed” once economic conditions improve; thus far, this has not proven universally true, nor is there any particular reason why it should prove true (unless you think that everybody everywhere is the same, that people are just little units of production and consumption differing only in input variables like education and net worth).
I’m not one to call for “death squads”, of course, but I do think people should be held responsible, to the extent possible, for the decisions they make. If they have more children then they can support, they should not be privileged to export or otherwise impose the consequences of their irresponsibility on the rest of us. Any humanitarian aid/technology we may offer to mitigate the otherwise inevitable consequences of such choices (such as famine), should be contingent upon their adopting policies that will lessen their future likelihood.
And no, the market won’t “provide,” either. The market “provides” whatever people want, if they can pay for it. When the population of Africa doubles again to 2 Billion in a few decades, if those 2 billion can not produce or otherwise acquire enough in value to trade for, say, the food they want (to stay alive), the market will provide them with starvation (absent exogenous intervention, of course).
As to why any of that is our problem (in the “West” or the “North” or whatever you’d like to call the places that have developed themselves),the idea that if we have something or build something we are somehow obliged to share it with teeming masses everywhere (who lack it and/or could never create it for themselves), well, that’s another goopy headed post-Christian bit of egalitarian blather.
The filthy hordes out there you pretend to care so much about, whose lack of (uninfected) water or food or clothes or the wheel or fire or anything else you want to lay on my head,
Those people hate you and want you dead. Well to the extent they are aware of you at all, of course. By all means, hop a plane to the Congo or Bangladesh or Libya or wherever, just don’t pretend any of it has anything to do with me.
