Amazing Progress in Artificial Intelligence – Ben Goertzel

At a recent conference in Beijing (the Global Innovators Conference) – I did yet another video interview with the legendary AGI guru – Ben Goertzel. This is the first part of the interview, where he talks about some of the ‘amazing’ progress in AI over recent years, including Deep Mind’s AlphaGo sealing a 4-1 victory over Go grandmaster Lee Sedol, progress in hybrid architectures in AI (Deep Learning, Reinforcement Learning, etc), interesting academic research in AI being taken up by tech giants, and finally providing some sobering remarks on the limitations of deep neural networks.

Can we build AI without losing control over it? – Sam Harris

San Harris (author of The Moral Landscape and host of the Waking Up podcast) discusses the need for AI Safety – while fun to think about, we are unable to “martial an appropriate emotional response” to improvements in AI and automation and the prospect of dangerous AI – it’s a failure of intuition to respond to it like one would a sci-fi like doom scenario.

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris — and not just in some theoretical way. We’re going to build superhuman machines, says Harris, but we haven’t yet grappled with the problems associated with creating something that may treat us the way we treat ants.

The Simulation Argument – How likely is it that we are living in a simulation?

The simulation hypothesis doesn’t seem to be a terse parsimonious explanation for the universe we live in. If what is most important is to simulate ancestors, what’s the motivation for all the hugely detailed rendering of space? Why not just simulate earth or our solar system or our galaxy?

People often jump to the conclusions and assume* that the great simulators have infinite computing power. Infinity – another thing we have never been able to measure 🙂 Max Tegmark wrote an interesting piece about why infinity is probably not real. Until we do have evidence of infinities in the real world, I believe we should treat all thought experiments that rely on infinities as mere intuition pumps.

Without the assumption that potential simulators have infinite computing power, but assume instead they have a finite amount – it seems logical that there would be a cost/benefit trade-off between computation and simulation, detail/number of sims that would need to be taken into account. Limits to available computation would decrease the motivation for building huge amounts of simulations and/or highly detailed simulations.

People think their way around the astronomical computational waste and add yet another extra assumption* that the simulation may grow to fill all the spaces we probe and interact with – though this would still increase the computational requirements to run the simulation. With this assumption, we should believe that if we are in a simulation, compared to just 500 years ago, it is costing the simulators a whole lot more to run now that we can stare into the depths of physics and peer about the universe. It has been argued that we should avoid building big computers or perform certain experiments because the simulators may decide to turn off our simulation because it begins costing them to much to run.

If we are in a simulation – many argue for the most part, it probably doesn’t matter. Based on Newcomb’s problem – even if we are in an elegant simulation, then the simulated laws of physics will behave just as they would if they were actual laws
If we feel compelled to put an estimate on it – the more we develop empirically informed naturalistic explanations for the universe, the lower our estimates should be that we are in a simulation.

If there are considerable costs to creating simulations with the detail of our universe – why simulate ancestors if it costs so much?
What is so important about ancestor simulations to justify the expense?

* the more assumptions we add to a hypothesis, the less certain we should be about it

The Seminal Nick Bostrom Interview

Here is the interview I did with Bostrom in 2012:

Why so much confidence that we are in a simulation?

I hear reports that Bostrom’s confidence that we are in a simulation have decreased over the years (less than 10% I heard recently – can’t find a direct reference right now) – while others, after he wrote the seminal paper, have increased their confidence quite dramatically. Based on various article headlines I am fairly certain that many latch onto a surface level understanding of the arguments that support their existing biases. So its probably best to read the paper and understand the Simulation Hypothesis and the Simulation Argument before hand waving about what Bostrom thinks.

How much credence should we give sound arguments that are empirically unfalsifiable?

I’d say some – not everything can be falsified – generally I rank arguments with empirical evidence higher than those that don’t.

I Wonder what do the Intelligent Design movement think of this?

Some atheists may be worried that such a philosophical implications – but most seem to think the Simulation Argument is cool.

Keith Wiley is the author of A Taxonomy and Metaphysics of Mind-Uploading, available on Amazon.

The ship of Theseus, also known as Theseus’ paradox, is a thought experiment that raises the question of whether an object that has had all of its components replaced remains fundamentally the same object. The paradox is most notably recorded by Plutarch in Life of Theseus from the late first century. Plutarch asked whether a ship that had been restored by replacing every single wooden part remained the same ship.

The paradox had been discussed by other ancient philosophers such as Heraclitus and Plato prior to Plutarch’s writings, and more recently by Thomas Hobbes and John Locke. Several variants are known, including the grandfather’s axe, which has had both head and handle replaced.

Note this is not a transcription of the video/audio interview.

The Ship of Theseus Metaphor

Adam Ford: Firstly, what is the story or metaphor of the Ship of Theseus intended to convey?

Keith Wiley: Around the first century AD, Plutarch wrote several biographies, including one of the king Theseus entitled Life of Theseus, in which he wrote the following passage:

The ship on which Theseus sailed with the youths and returned in safety, the thirty-oared galley, was preserved by the Athenians down to the time of Demetrius Phalereus. They took away the old timbers from time to time, and put new and sound ones in their places, so that the vessel became a standing illustration for the philosophers in the mooted question of growth, some declaring that it remained the same, others that it was not the same vessel.Plutarch

People sometimes erroneously believe that Plutarch presents the scenario (replacing a ship piecemeal style until all original material is absent) with a conclusion or judgment, i.e., that it makes some prescription of the “correct” way to interpret the scenario (as to, yes or no, is the ship’s identity preserved). However, as you see from the passage above, this is not the case. Plutarch left the question open. He mere poses the question and leaves it to the reader to ruminate on an actual answer.

The specific questions in that scenario are:

  • Does identity require maintaining the same material components? Aka, is identity tied and indicated by specific sets of atoms?
  • If not, then does preservation of identity require some sort of temporally overlapping sequence of closely connected parts?

The more general question being asked is: What is the nature of identity? What are its properties? What are its requirements (to claim preservation under various circumstances)? What traits specify identity and indicate the transformations under which identity may be preserved and under which it is necessarily lost?

Here is a video explainer by Keith Wiley (intended to inspire viewers to think about identity preservation)

Adam Ford: How does this story relate to mind uploading?

Keith Wiley: The identity of relatively static objects, and of objects not possessing minds or consciousness, is an introduction to the thornier question of metaphysical personal identity, i.e., the identity of persons. The goal in considering how various theories of identity describe what is happening in the Ship of Theseus is to prime our thinking about what happens to personal identity of people in analogous scenarios. For example, in a most straightforward manner, the Ship of Theseus asks us to consider how our identity would be affected if we replaced, piecemeal style, all the material in our own bodies. The funny thing is, this is already the case! It is colloquially estimated that our bodies turn over their material components approximately every seven years (whether this is precisely accurate is beside the point). The intent is not that a conclusion drawn from the Ship of Theseus definitively resolves the question concerning personal identity, because the former is a much simpler scenario. The critical distinction is that people are more obviously dynamic across time than static physical objects because our minds undergo constant psychological change. This raises the question of whether some sort of “temporal continuity” is at play in people that does not take effect in ships. There is also the question of whether consciousness somehow changes the discussion in radical ways. So the Ship of Theseus is not conclusive on personal identity. It is just a way to get us started in thinking about such issues.

Adam Ford: Fishing for clarification on how you use the term ‘identity’, Robin Hanson (scenario of uploads in the future in Age of Em) enquired about what kind of identity concept you are interested in. That is, what function do you intend this concept to serve?

Keith Wiley: Sure. First, and this might not be what Robin meant, there are different fundamental kinds of identity, two big ones being quantitative and numerical. Two things quantitatively identified possess the same properties, but are not necessarily “the same entity”. Two things numerically identical are somehow “the same thing”, which is problematic in its phrasing since they were admitted to be “two things” to begin with. The crucial distinction is in whether numerical identity makes any difference, or whether quantitative identity is all the fundamentally matters.

For me, I phrase the crucial question of personal identity relative to mind uploading in the following way: Do we grant equal primacy to claims to the original single identity to all minds (people) who psychologically descend from that common ancestral mind (person)? I always phrase it this way: granting primacy in claims to a historical identity. Do we tolerate the metaphysical interpretation that all descendant minds are equal in the primacy of their claim to the identity they perceive themselves to be? Alternatively, do we disregard such claims, dictating to others that they are not, in fact, who they believe themselves to be, and that they are not entitled to the rights of the people they claim to be? My concern is of:
bias (differing assignments of traits to various people),
prejudice (differing assignments of values, claims, or rights resulting from bias),
and discrimination (actions favoring and dismissing various people, resulting from prejudices).

Adam Ford: Is ‘identity’ the most appropriate word to be using here?

Keith Wiley: Well, identity certainly doesn’t seem to fully “work”. There’s always some boundary case or exception that undermines any identity theory we attempt to assign. My primary concern, such as it is on an entirely abstract philosophical musing (at this point in history when mind uploading isn’t remotely possible yet) is only secondarily the nature of identity. The primary concern, justified by those secondary aspects of identity, is whether we should regard uploads in some denigrated fashion. Should we dismiss their claims that they are the original person, that they should be perceived as the original person, that they should be treated and entitled and “enrighted” as the original person? I don’t just mean from a legal standpoint. We can pass all sorts of laws that force people to be respectful, but that’s an uninteresting question to me. I’m asking if it is fundamentally right or wrong to regard an upload in a denigrated way when judging its identity claims.

Ontology, Classification & Reality

Adam Ford: As we move forward the classification of identity will likely be fraught with struggle. We might need to invent new words to clarify the difference between distinct concepts. Do you have any ideas for new words?

Keith Wiley: The terminology I generally use is that of mind descendants and mind ancestors. In this way we can ask whether all minds descending from a common ancestral mind should be afforded equal primacy in their claim to the ancestral identity, or alternatively, whether there is a reasonable justification to exhibit biases, prejudices, and discriminations against some minds over such such questions. Personally, I don’t believe any such asymmetry in our judgment of persons and their identity claims can be grounded on physical or material traits (such as whose brain is composed of more matter from the ancestral brain, which comes up when debating nondestructive uploading scenarios).

Adam Ford: An appropriate definition for legal reasons?

Keith Wiley: I find legal distinctions to be uninteresting. It used to be illegal for whites and blacks to marry. Who cares what the law says from a moral, much less metaphysical, perspective. I’m interested in finding the most consistent, least arbitrary, and least paradoxical way to comprehend reality, including the aspect of reality that describes how minds relate to their mental ancestors.

Adam Ford: For scientific reasons?

Keith Wiley: I don’t believe this is a scientific question. How to procedurally accomplish uploading is a scientific question. Whether it can be done in a nondestructive way, leaving the original body and brain unharmed, is a scientific question. Whether multi-uploading (producing multiple uploads at once) is technically possible is a scientific question, say via an initial scan that can be multi-instantiated. I think those are crucial scientific endeavors that will be pursued in the future, and I participate in some of the discussions around that research. But at this point in history, when nothing like mind uploading is possible yet, I am pursuing other aspects, nonscientific aspects, namely the philosophical question of whether we have the correct metaphysical notion of identity in the first place, and whether we are applying identity theories in an irrational, or even discriminatory, fashion.

Implications for Brain Preservation

Adam Ford: Potential brain preservation (inc cryonics) customers may be interested in knowing the possible likely science of reanimation (which, it has been suggested, includes mind uploading) – and the type of preservation which will most likely achieve the best results. Even though we don’t have mind uploading yet – people are committing their brains to preservation strategies that are to some degree based on strategies for revival. Mummification? No – that probably won’t work. Immersion in saline based solution? Yeah for short periods of time. Plastination? Yes but only if it’s the connectome we are after… And then there is different methods of cryonic suspension that may be tailored to different intended outcomes – do you want to destructively scan the brain layer by layer and be uploaded in the future? Do you want to be able to fully revive the actual brain in the (potentially in a longer term future)?

Keith Wiley: People closer to the cryonics community than myself, such as some of my fellow BPF board members, claim that most current cryonics enthusiasts (and paying members or current subjects) are not of the mind uploading persuasion, preferring biological revival instead. Perhaps because they tend to be older (baby boomer generation) they have not bought into computerization of brains and minds. Their passion for cryonics is far more aligned with the prospect of future biological revival. I suspect there will be a shift toward those of a mind uploading persuasion as the newer generations, more comfortable with computers, enter the cryonics community.

As you described above, there are few categories of preservation and a few paths of potential revival. Preservation is primarily of two sorts: cryogenic and at least conceivably reversible, and room temperature and inconceivably reversible. The former is amenable to both biological revival and mind uploading. The latter is exclusively amenable to mind uploading. Why would one ever choose the latter option then? Simple: it might be the better method of preservation! It might preserve the connectome in greater detail for longer periods of time with lesser rates of decay — or it might simply be cheaper or otherwise easier to maintain over the long term. After all, cryonic storage requires cryonic facilities and constant nitrogen reintroduction as it boils off. Room temperature storage can be put on the shelf and forgotten about for millennia.

Adam Ford: What about for social (family) reasons?

Keith Wiley: This is closer to the area where I think and write, although not necessarily in a family-oriented way. But social in terms of whether our social contracts with one another should justify treating certain people in a discriminatory fashion and whether there is a rational basis for such prejudices. Not that any of this will be a real-world issue with which to tackle for quite some time. But perhaps some day…

Adam Ford: If the intended outcomes of BP are for subjective personal reasons?

Keith Wiley: I would admit that much of my personal interest here is to try to grind out the absolutely most logical way to comprehend minds and identity relative to brains, especially under the sorts of physical transformations that brains could hypothetically experience (Parfit’s hemispherical fission, teleportation, gradual nanobot replacement, freeze-slice-scan-and-emulate, etc.).

Philosophy

Adam Ford: In relation to appropriate definitions of ‘identity’ for scientific reasons – what are your thoughts on the whole map/territory ‘is science real’ debate? Where do you sit – scientific realism, anti-realism and structural realism (epistemic or ontic)? what’s your favorite?

Keith Wiley: I suppose I lean toward scientific realism (to my understanding: scientific claims and truths hold real truth value, not just current societal “perspective”, and further they can be applied to yet-to-be observed phenomena), although antirealism is a nifty idea (scientific truths are essentially those which we have yet to disprove, but expect to with some future overturning, or furthermore, unobserved phenomena are not reasonable subjects of scientific inquiry). The reason I don’t like the latter is it leads to antiintellectualism, which is a huge problem for our society. Rather than overturning or disregarding scientific theories, I prefer to interpret it as that we refine them, saying that new theories apply in corners where the old ones didn’t fit well (Newton’s laws are fine in many circumstances, but are best appended by quantum mechanics at the boundary’s of their applicability). Structural and ontic realism are currently vague to me. I’ve read about them but haven’t really grinded through their implications yet.

Adam Ford: If we are concerned about our future and the future of things we value we perhaps should ask a fundamental question: How do things actually persist? (Whether you’re a perdurantist or an endurantist – this is still a relevant question – see 5.2 ‘How Things Persist?’ in ‘Endurantism and Perdurantism’)

Keith Wiley: Perdurantism and Endurantism are not terms I have come across before. I do like the idea of conceptualizing objects as 4D temporal “worms”. I describe brains that way in my book for example. If this is the “right” way (or at least a good way) to conceive of the existence of physical objects, then it partially solves the persistence or preservation-of-identity problem: preservation of identity is the temporal stream of physical continuity. The problem is, I reject any physical requirement for explicitly *personal* identity of minds, because there appears to be no associated physical trait — plus that would leave open how to handle brain fission, ala Parfit, so worms just *can’*t solve the problem of personal identity, only of physical objects.

Adam Ford: Cybernetics – signal is more important than substrate – has cybernetics influenced your thinking? If so, how?

Keith Wiley: If by signal, you mean function, then I’ve always held that the functional traits of the brain are far more important (it not entirely more important) than mere material components.

Adam Ford: “signal is more important than substrate” – Yet the signal quality depends on the substrate – surely a ship’s substrate is not as tightly coupled to its function of moving across a body of water (wood, fiberglass, even steel will work) than a conscious human mind is to its biological brain. in terms of the granularity of replacement part – how much is needed?

Keith Wiley: Good question. I have no idea. I tend to presume the requisite level is action potential processing and generation, which is a pretty popular assumption I think. We should be open on this question at this time in history and current state of scientific knowledge.

Adam Ford: What level of functional representation is needed in order to be preserve ‘selfhood’?

Keith Wiley: Short answer: We don’t know yet. Long answer, it is widely presumed that the action-potential patterns of the connectome are where the crucial stuff is happening, but this is a supposition. We don’t know for sure.

Adam Ford: A Trolley Problem applied to Mind Uploaded Clones: As with the classic trolley problem, a trolley is hurtling down a track towards 5 people. As in the classic case, you can divert it onto a separate track by pulling a nearby leaver. However, suddenly 5 functionally equivalent carbon copies* of the original 5 people appear on the separate track. Would you pull the lever to save the originals but kill the copies? Or leave the originals to die, saving the copies? (*assume you just know the copies are functionally equivalent to the originals)

Keith Wiley: Much of my writing focuses on mind uploading and the related question of what minds are and what personal identity is. My primary claim is that uploads are wholly human in their psychological traits and human rights, and furthermore that they have equal primacy in their claim to the identity of the person who preceded an uploading procedure — even if the bio-original body and brain survive! The upload is still no less “the original person” than the person housed in the materially original body, precisely because bodies and material preservation are irrelevant to who we are, by my reckoning. If this is not the case, then how can we solve the fission paradox? Who gets to “be the original” if we split someone in two? The best solution is that only psychological traits matter and material traits are simply irrelevant.

So, for those reasons, I would rephrase your trolley scenario thusly: track one has five people, track two has five other people. Coincidentally, pairs of people from each track have very recently diverging memories, but the scenario is psychologically symmetrical between the two tracks even if there is some physical asymmetry in terms of how old the various material compositions (bodies) are. So we can disregard notions of asymmetry for the purpose of analyzing the moral or identity-preserving-killing implications of the trolley problem. It is simply “Five people on one track, five on another. Should you pull the lever, killing those on the diverted track to save those on the initial track?” That’s how I rephrase it.

Adam Ford: I wonder if the experiment would yield different results if there were 5 individuals on one track and 6 copies of 1 person on the other? (As some people suggest that copies are actually identical to the original – eg for voting purposes)

Keith Wiley: But they clearly aren’t identical in the scenario you described. The classic trolley problem has always implied that the subjects are reasonably alert and mentally dynamic (thinking). It isn’t carefully described so as to imply that the people involved are explicitly unconscious, to say nothing of the complexities involved in rendering them as physically static objects (preserved brains undergoing essentially no metabolic or signal-processing (action potentials) activity. The problem is never posed that way. Consequently, they are all awake and therefore divergent from one another, distinct individuals with all the rights of individual personhood. So it’s just five against six in your example. That’s all there is to it. People might suggest, as you said above, that copies are identical to each other (or to the original), but those people are just wrong.

So an interesting question then, is what if the various subjects involved actually are unconscious or even rigidly preserved? Can we say their psychological sequences have not diverged and that they therefore represent redundant physical instantiations of a given mind? I explore this exact question in my book by the way. I think a case could be made that until psychological divergence (until the brains are rolling forward through time, accumulating experiences and memories) we can say they are redundant in terms of identity and associated person-value. But to be clear, if the bio-original was statically preserved, then uploaded or duplicated, and then both people were put on the train tracks in their preserved state, physically identical, frozen with no ongoing psychological experience, then I would be clear to state that while it might not matter if we kill the upload, it *also* doesn’t matter if we choose the other way and kill the bio-original! That is the obvious implication of my reasoning here. And in your case above, if we have five distinct people on one track (let’s stay everyone involved is statically preserved) and six uploads of one of those people on the other track, then we could recast the problem as “five on one track and one on the other”. The funny thing is, if we save the six and revive them, then, after the fact, we have granted life to six distinct individuals, but we can only say that after we revive them, not at the time of the trolley experiment when they are statically preserved. So now we are speculating on the “tentative” split personhood of a set of identical but static minds based on a later time when they might be revived. Does that tentative individuality grant them individuality while they are still preserved? Does the mere potential to diverge and individualize grant them full-blown distinct identity before the divergence has occurred? I don’t know. Fascinating question. I guess the anti-abortion-choice and pro-abortion-choice debate has been trying to sort out the personhood of tentative, potential, or possible persons for a long time (and by extension, whether contraception is acceptable hits the same question). We don’t seem to have all agreed on a solution there yet, so we probably won’t agree in this case either.

Philosophy of identity

Adam Ford: Retention of structure across atomic change – is identity the structure, the atomic composition, the atomic or structural continuum through change, or a mixture?

Keith Wiley: Depends on one’s chosen theory of identity of course. Body theory, psychological theory, psychological branching theory, closest continuer theory, 4D spacetime “worm” theory. There’s several to choose from — but I find that some more paradox-prone than others, and I generally take that as an indication of a weak theory. I’m a branchest, although the distinction from worm theory is, on some accounts, virtually indistinguishable.

Adam Ford: Leibniz thought about the Identity of indiscernibles (principle in ontology that no two things can have all properties the same) – if objX and objY share all the same properties, are they the same thing? If KeithX and KeithY share the same functional characteristics are they the same person?

Keith Wiley: But do they really share the same properties to begin with, or is the premise unfounded? When people casually analyze these sorts of scenarios, the two people are standing there, conscious, wondering if someone is about to pass judgment on them and kill them. They are experiencing the world from slightly different sensorial vantage points (vision, sound, etc.) Their minds are almost certainly diverged in their psychological state mere fractions of a second upon regaining consciousness. So they aren’t functionally identical in the first place. Thus the question is flawed, right? The question can only be applied if they are unconscious and rigidly preserved (frozen perhaps). Although I believe a case could be made that mere lack of consciousness is sufficient to designate them *psychologically* identical even if they are not necessarily physically identical due to microscopic metabolic variations — but I leave that subtly as an open question for the time being.

Adam Ford: Here is a Symmetric Universe counterexample – Max Black – two distinct perfect spheres (or two Ship of Theseuses) are two separate objects even though they share all the same properties – but don’t share the same space-time. What are your thoughts?

Keith Wiley: This is very close to worm theory. It distinguishes seemingly identical entities by considering their spacetime worms, which squiggle their way through different spacetime paths and are therefore not identical in the first place. They never were. The reason they appeared to be identical is that we only considered 3D space projection of their truly 4D spacetime structure. You can easily alias pairs of distinct higher-dimensional entities by looking only at their projections onto lower dimensions and thereby wrongly conclude that they are identical when, in fact, they never were to begin with in their true higher dimensional structure. For example, consider two volumes, a sphere and a cylinder. They are 3D. But project them onto a 2D plane (at the right angle) and you get two circles. You might wrongly conclude they are identical, but they weren’t to begin with! You simply ignored an entire dimension of their nature. That’s what the 4D spacetime worm says about the identity of physical objects.

However, once we dismiss any relevance or importance of physical traits anyway (because I reject body identity on the matter of personal identity, favoring psychological identity), then the 4D worm becomes more convoluted. The question then becomes, what sort of “time worm” describes psychological changes over time instead of physical, structure, and material changes over time? I think it’s as simple as: take an information pattern instantiated in a physical system (a brain), produce a second physical instantiation, and now readily conclude that the psychological temporal worm (just a temporal sequence of psychological states frankly) has diverged.

Adam Ford: Nice answer! – I’m certainly interested in hearing more about worm theory – I think this wikipedia source is about the same thing: https://en.wikipedia.org/wiki/Perdurantism
Do you have any personal writings I can point at in the text form of the interview?

Keith Wiley: Ah, I hadn’t heard that term before. Thanks for the reference. Well, I always refer to my book of course, and more recently Randal Koene and I published a paper in the Journal of Consciousness Studies this past March.

(See Free near-final version on arxiv

Adam Ford: David Pearce is skeptical that our we as in our subjects of experience are actually enduring metaphysical egos – he seems more of a stage theorist – that each moment of subjective experience is fleeting – only persisting through one cycle of quantum cohesion delimited by decoherence.

Keith Wiley: Hmmm, I see the distinction in the link to stage theorist you provided above, and I do not believe I am committed to a position on that question. I go both ways in my own writing, sometimes describing things as true 4D entities (I describe brains that way in my book) but also writing quite frequently in terms of “mind descendants of mind ancestors”. That phrasing admits that perhaps identity does not span time in a temporal worm, but rather that it consists of instantaneous time slices of momentary identity connected in a temporal sequence. Like I said, I am uncommitted on this distinction, at least for now.

Identity: Accidental properties vs Essential properties

Adam Ford: Is the sense of an enduring metaphysical ego really an ‘accidental property’ (based on our intuitions of self) rather than an ‘essential property’ of identity?

Keith Wiley: It is possible we don’t yet know what a mind is in sufficient detail to answer such a question. I confess to not being entirely sure what the question is asking. That said, it is possible that conscious and cognitively rich aliens have come up with a fairly different way of comprehending what their minds actually are, and consequently may also have rather bizarre notions of what personal identity is.

Note that in the video, I sometimes offer an answer to the question “Did we preserve the ship in this scenario?” and I sometimes don’t, simply asking the viewer “So did we preserve it or not? What do you think?” This is because I’m certainly not sure of all the answers to this question in all the myriad scenarios yet.

Adam Ford: This argument is criticized by some modern philosophers on the grounds that it allegedly derives a conclusion about what is true from a premise about what people know. What people know or believe about an entity, they argue, is not really a characteristic of that entity.
There may be a problem in that what is true about a phenomenon or object (like identity) shouldn’t be derived from how we label or what we know about it – the label or description isn’t a characteristic of the identity (map not the territory etc).

Keith Wiley: I would essentially agree that identity shouldn’t merely be a convention of how we arbitrarily label things (i.e., that labeling grants or determines identity), but rather the reverse, that we are likely to label things so as to indicate how we perceive their identity. The question is, does our perception of identity indicate truth, which we then label, or does our perception determine or choose identity, which we then label? I would like to think reality is more objective than that, that there at least some aspects of identity that aren’t merely our choices, but rather traits of the world that we discover, observe, and finally label.

Definitions


Perdure – remain in existence throughout a substantial period of time; persisting in virtue of having both temporal and spatial parts (alternatively the thesis that objects are four dimensional and have temporal parts)
Endure – being wholly present at all times at which it exists (endurance distinct from perducance in that endurance has strict identity and perdurance has a looser unity relation (genidentity))
Genidentity – is an existential relationship underlying the genesis of an object from one moment to the next.
Gunk – In mereology, an area of philosophical logic, the term gunk applies to any whole whose parts all have further proper parts. That is, a gunky object is not made of indivisible atoms or simples. Because parthood is transitive, any part of gunk is itself gunk.

Longevity Day with Aubrey de Grey!

“Longevity Day” (based on the UN International Day of Older Persons – October 1) is a day of support for biomedical aging and longevity research. This has been a worldwide international campaign successfully adopted by many longevity activists groups. In this interview Aubrey de Grey lends support to Longevity Day and covers a variety of points, including:

An Overview of Models of the Technological Singularity

anders-sandberg-technology-feedback-loopsSee Anders’ paper ‘An overview of models of technological singularity
This paper reviews different definitions and models of technological singularity. The models range from conceptual sketches to detailed endogenous growth models, as well as attempts to fit empirical data to quantitative models. Such models are useful for examining the dynamics of the world-system and possible types of future crisis points where fundamental transitions are likely to occur. Current models suggest that, generically, even small increasing returns tends to produce radical growth. If mental capital becomes copyable (such as would be the case for AI or brain emulation) extremely rapid growth would also become likely.

[The] Technological singularity is of increasing interest among futurists both as a predicted possibility in the midterm future and as subject for methodological debate. The concept is used in a variety of contexts, and has acquired an unfortunately large number of meanings. Some versions stress the role of artificial intelligence, others refer to more general technological change. These multiple meanings can overlap, and many writers use combinations of meanings: even Vernor Vinge’s seminal essay that coined the term uses several meanings. Some of these meanings may imply each other but often there is a conflation of different elements that likely (but not necessarily) occur in parallel. This causes confusion and misunderstanding to the extent that some critics argue that the term should be avoided altogether. At the very least the term ‘singularity’ has led to many unfortunate assumptions that technological singularity involves some form of mathematical singularity and can hence be ignored as unphysical.Anders Sandberg

A list of models described in the paper:

A. Accelerating change

Exponential or superexponential technological growth (with linked economical growth and social change) (Ray Kurzweil (Kur05), John Smart (Smang))

B. Self improving technology

Better technology allows faster development of new and better technology. (Flake (Fla06))

C. Intelligence explosion

Smarter systems can improve themselves, producing even more intelligence in a strong feedback loop. (I.J. Good (Goo65), Eliezer Yudkowsky)

D. Emergence of superintelligence

(Singularity Institute) 1

E. Prediction horizon

Rapid change or the emergence of superhuman intelligence makes the future impossible to predict from our current limited knowledge and experience. (Vinge, (Vin93))

F. Phase transition

The singularity represents a shift to new forms of organisation. This could be a fundamental difference in kind such as humanity being succeeded by posthuman or artificial intelligences,
a punctuated equilibrium transition or the emergence of a new meta-system level. (Teilhard de Chardin, Valentin Turchin (Tur77), Heylighen (Hey07))

G. Complexity disaster

Increasing complexity and interconnectedness causes increasing payoffs, but increases instability. Eventually this produces a crisis, beyond which point the dynamics must be different.
(Sornette (JS01), West (BLH+07))

H. Inflexion point

Large-scale growth of technology or economy follows a logistic growth curve. The singularity represents the inflexion point where change shifts from acceleration to de-acceleration. (Extropian
FAQ, T. Modis (Mod02))

I. Infinite progress

The rate of progress in some domain goes to infinity in nite time. (Few, if any, hold this to be plausible 2 )

Zombie Rights

andrew-dun-zombie-rightsAndrew Dun provides an interesting discussion on the rights of sentient entities. Drawing inspiration from quantum complementarity, defends a complementary notion of ontological dualism, countering zombie hypotheses. Sans zombie concerns, ethical discussions should therefore focus on assessing consciousness purely in terms of the physical-functional properties of any putatively conscious entity.

Below is the video of the presentation:

At 12:17 point, Andrew introduces the notion of Supervenience (where high level properties supervene on low-level properties) – do zombies have supervenience? Is consciousness merely a supervenient property that supervenes on characteristics of brain states? If so, we should be able to compute whether a system is conscious (if we do know its full physical characterization). The zombie hypothesis suggests that consciousness does not logically supervene on the physical.

Slides for presentation can be found on slide-share!


Andrew Dun spoke at the Singularity Summit. Talk title : “Zombie Rights”.

Andrew’s research interest relates to both the ontology and ethics of consciousness. Andrew is interested in the ethical significance of consciousness, including the way in which our understanding of consciousness impacts our treatment of other humans, non-human animals, and artifacts. Andrew defends the view that the relationship between physical and conscious properties is one of symmetrical representation, rather than supervenience. Andrew argues that on this basis we can confidently approach ethical questions about consciousness from the perspective of ‘common-sense’ materialism.

Andrew also composes and performs original music.

Extending Life is Not Enough

Dr Randal Koene covers the motivation for human technological augmentation and reasons to go beyond biological life extension.

randal_koene_squareCompetition is an inescapable occurrence in the animate and even in the inanimate universe. To give our minds the flexibility to transfer and to operate in different substrates bestows upon our species the most important competitive advantage.” I am a neuroscientist and neuroengineer who is currently the Science Director at Foundation 2045, and the Lead Scientist at Kernel, and I head the organization carboncopies.org, which is the outreach and roadmapping organization for the development of substrate-independent minds (SIM) and also previously participated in the ambitious and fascinating efforts of the nanotechnology startup Halcyon Molecular in Silicon Valley.

Points discussed in the talk:
1. Biological Life-Extension is Not Enough Randal A. Koene Carboncopies.org
2. PERSONAL
3. No one wants to live longer just to live longer. Motivation informs Method.
4. Having an Objective, a Goal, requires that you have some notion of success.
5. Creating (intelligent) machines that have the capabilities we do not — is not as good as being able to experience them ourselves… Imagine… creating/playing music. Imagine… being the kayak.Imagine… perceiving the background radiation of the universe.
6. Is being out of the loop really your goal?
7. Near-term goals: Extended lives without expanded minds are in conflict with creative development.
8. Social
9. Gene survival is extremely dependent on an environment — it is unlikely to survive many changes.Worse… gene replication does not sustain that which we care most about!
10. Is CTGGAGTAC better than GTTGACTGAC? We are vessels for that game — but for the last10,000 years something has been happening!
11. Certain future experiences are desirable, others are not — these are your perspectives, the memes you champion…Death keeps stealing our champions, our experts.
12. Too early to do uploading? – No! The big perspective is relevant now. We don’t like myopic thinking in our politicians, lets not be myopic about world issues ourselves.
13. SPECIES
14. Life-extension in biology may increase the fragility of our species & civilization… More people? – Resources. Less births? – Fewer novel perspectives. Expansion? – Environmental limitation.
15. Biological life-extension within the same evolutionary niche = further specialization to the same performance “over-training” in conflict with generalization
16. Aubrey de Grey: Ultimately, desires “uploading”
17. TECHNICAL
18. Significant biological life-extension is incredibly difficult and beset by threats. Reality vs. popular perception.
19. Life-extension and Substrate-Independence are two different objectives
20. Developing out of a “catchment area” (S. Gildert) may demand iterations of exploration — and exploration involves risk.Hard-wired delusions and drives. What would an AGI do? Which types of AGI would exist in the long run?
21. “Uploading” is just one step of many — but a necessary step — for a truly advanced species

‘Wake Enhancement’: Is sleep better than medicine?

‘Wake Enhancement’: Is sleep better than medicine?
Are well rested people happier and more productive people?

We have ways of making people go to sleep, and ways of preventing people going to sleep – but that’s not nessecarily the best solution. The best solution is guaranteed 8 hours of sleep.Anders Sandberg

Generally anecdotal feedback from grinders, transhumanists and futurists that I have met with often get into the habit of loosing sleep, and depending on coffee or other nutropics like modafinil to get through the day – while this can help as a palliative to easing the effects of not getting enough sleep – they shouldn’t be seen as replacements to a full night of sleep.  Perhaps at some stage in the future we will have technology that can effectively replace sleep – though as of 2016, it is not here yet.
According to the National Sleep Foundation in America, the recommended sleep time for adults from 18-65 is 7-9 hours and 7-8 hours for those over 65.

This video is the product of an unscripted conversation as part of an interview series with Oxford scholar Anders Sandberg – it turned out quite interesting.

* Also see other sections of the interview in this playlist!

The cycle of sleeping during the night and waking up at dawn is a natural part of human life that arguably has been with us and our ancestors for 100’s of thousands of years – yet very recently scientists begun to understand the relationship between daylight/darkness to the alternating cycle of sleep and waking. Melatonin is a natural hormone produced by the body’s pineal gland which helps regulate sleep patterns – it is also found in some foods – and may be useful as a supplement to help get the body’s circadian rhythm. approval by the FDA).

The NSA has an article on Melatonin which says “For melatonin to be helpful, the correct dosage, method and time of day it is taken must be appropriate to the sleep problem. Taking it at the “wrong” time of day may reset your biological clock in an undesirable direction. How much to take, when to take it, and melatonin’s effectiveness, if any, for particular sleep disorders is only beginning to be understood.”

[Referring to Melatonin pills] Now that’s useful because you can reset your diurnal rhythm. Now typically jet-lag is nasty because your brain is out of synch – it’s sending signals to the rest of the body on what it’s supposed to do that doesn’t fit your activity – so everything goes a bit haywire. Melatonins kind of good because it cuts in a reset signal – right now, it’s just after midnight.” – Anders Sandberg

The judicious use of Melatonin supplements can aid in helping your body adjust back into an effective sleeping pattern – and for most cases, is likely to be a wiser option than taking ‘sleeping pills‘.

Sleeping pills shut you down well enough so that you get unconscious at least, but it’s not necessarily that you get good sleep – because during sleep your doing memory consolidation among a lot of other things. So that’s an interesting issue that during the day we want to learn things quickly – we need to get a lot of information. And then we want to store it permenantly but if you learn quickly into your memory, it can erase it quickly too. So ideally you want to re-write it at a slower rate – you actually want to have a kind of write protection on part of your brain. Now that’s probably what’s going on during sleep. During deep sleep the hyppocampus can replay what you have learned during the day – especially the stuff that turned out to be important – to the rest of the brain to store it more safely. And without sleep of course, you’re not going to do that very well.Anders Sandberg

11 Tips to help you achieve quality sleep

Here are 11 tips from the NSA to help you get some extra sleep:

  1. Stick to a sleep schedule of the same bedtime and wake up time, even on the weekends. This helps to regulate your body’s clock and could help you fall asleep and stay asleep for the night.
  2. Practice a relaxing bedtime ritual. A relaxing, routine activity right before bedtime conducted away from bright lights helps separate your sleep time from activities that can cause excitement, stress or anxiety which can make it more difficult to fall asleep, get sound and deep sleep or remain asleep.
  3. If you have trouble sleeping, avoid naps, especially in the afternoon. Power napping may help you get through the day, but if you find that you can’t fall asleep at bedtime, eliminating even short catnaps may help.
  4. Exercise daily. Vigorous exercise is best, but even light exercise is better than no activity. Exercise at any time of day, but not at the expense of your sleep.
  5. Evaluate your room. Design your sleep environment to establish the conditions you need for sleep. Your bedroom should be cool – between 60 and 67 degrees. Your bedroom should also be free from any noise that can disturb your sleep. Finally, your bedroom should be free from any light. Check your room for noises or other distractions. This includes a bed partner’s sleep disruptions such as snoring. Consider using blackout curtains, eye shades, ear plugs, “white noise” machines, humidifiers, fans and other devices.
  6. Sleep on a comfortable mattress and pillows. Make sure your mattress is comfortable and supportive. The one you have been using for years may have exceeded its life expectancy – about 9 or 10 years for most good quality mattresses. Have comfortable pillows and make the room attractive and inviting for sleep but also free of allergens that might affect you and objects that might cause you to slip or fall if you have to get up
  7. During the night Use bright light to help manage your circadian rhythms. Avoid bright light in the evening and expose yourself to sunlight in the morning. This will keep your circadian rhythms in check.
  8. Avoid alcohol, cigarettes, and heavy meals in the evening. Alcohol, cigarettes and caffeine can disrupt sleep. Eating big or spicy meals can cause discomfort from indigestion that can make it hard to sleep. If you can, avoid eating large meals for two to three hours before bedtime. Try a light snack 45 minutes before bed if you’re still hungry.
  9. Wind down. Your body needs time to shift into sleep mode, so spend the last hour before bed doing a calming activity such as reading. For some people, using an electronic device such as a laptop can make it hard to fall asleep, because the particular type of light emanating from the screens of these devices is activating to the brain. If you have trouble sleeping, avoid electronics before bed or in the middle of the night.
  10. If you can’t sleep, go into another room and do something relaxing until you feel tired. It is best to take work materials, computers and televisions out of the sleeping environment. Use your bed only for sleep and sex to strengthen the association between bed and sleep. If you associate a particular activity or item with anxiety about sleeping, omit it from your bedtime routine.
  11. If you’re still having trouble sleeping, don’t hesitate to speak with your doctor or to  find a sleep professional. You may also benefit from recording your sleep in a Sleep Diary  to help you better evaluate common patterns or issues you may see with your sleep or sleeping habits.

 

Notes, References & Extra Reading

See Anders’ page on ‘Optimized Sleep

Consider reading Anders’ paper: ‘Sleep better than medicine? Ethical issues related to “wake enhancement”

Abstract: This paper deals with new pharmacological and technological developments in the manipulation and curtailment of our sleep needs. While humans have used various methods throughout history to lengthen diurnal wakefulness, recent advances have been achieved in manipulating the architecture of the brain states involved in sleep. The progress suggests that we will gradually become able to drastically manipulate our natural sleep-wake cycle. Our goal here is to promote discussion on the desirability and acceptability of enhancing our control over biological sleep, by illustrating various potential attendant ethical problems. We draw attention to the risks involved, possible conflicts of interests underlying the development of wake enhancement, and the potential impact on accountability for fatigue related errors.

Singularity Skepticism or Advocacy – to what extent is it warranted?

Why are some people so skeptical of the possibility of Super-intelligent Machines, while others take it quite seriously?
Hugo de Garis addresses both ‘Singularity Skepticism’ and advocacy – reasons for believing machine intelligence is not only possible but quite probable!
The Singularity will likely be an unprecedentedly huge issue that we will need to face in the coming decades.

Singularity Skepticism - Hugh de Garis. 2jpg

If you take the average person in the street and you talk to them about a future intelligent machine – there is a lot of skepticism – because today’s machines aren’t intelligent right? I know from my own personal experience that I get incredibly frustrated with computers, they crash all the time, they don’t do what I want… literally I say “I hate computers” but I really love them – so I have an ambivalent relationship with computers..Hugo de Garis
.

The exponential growth of technology and resolution of brain-scanning may lead to advanced neuro-engineering. Brain simulation right down to the chemical synapse, or just plain old functional brain representation might be possible within our lifetimes – this would likely lead to a neuromorphic flavour of the singularity.

There have been some enthusiastic and skeptical responses to this video so far on YouTube:

AZR NSMX1 commented that “Computers already have a better memory and a higher speed than human brain, they can learn and recognice the human voice since 1982 with the first software made for Kurzweil Industries, the expert systems are the first steps for thinking, then in 90’s we learned that emotions are more easy for machines than we believed, an emotion is just an uncontrolled reaction an automatic preservation code that may be good or not for a robot to reach its goal. Now in 2010 the Watson supercomputer show us that is able to structure the human language to produce a logic response, if that is not what does the thought, then somebody explain me what means to think. The only thing they still can’t do is the creative thinking and conciousness, but that will be reached between 2030 and 2035. Conciousness is just the amout and quality of the information you can process, IBM Blue Brain team said this, for example we the humans are very stupid when it comes to use and exploit all the possibilities offered by the smell sense compared to dogs or bears, in this dimension a cockroach is smarter than us because they can map the direction of smell to find the food or other members of their group, we can’t do this, we just have no consciusness in that world. Creativity is the most complex thing, if machines reaches creativity then our world will change because we will not only have to work anymore, but what is better we will not have to think anymore haha. Machines gonna do everything.”
 My response: There has certainly been some impressive strides in technological advancement, it might asymptote at some stage – not sure when, but my take is that there won’t likely be many fundamental engineering or scientific bottlenecks that will block or stifle progress – the biggest problems I think will be sociological impediments – human caused. 

Darian Rachel says “Around the 8 minute or so point he makes a statement that a machine will be built that is intelligent and conscious. He seems to pull this idea that it will be conscious “out of the air” somewhere. It seems to be a rather silly idea.”
 My response: while I agree that a conscious machine is likely difficult to build, there doesn’t seem to be much agreement among humans about whether it exists, what consciousness actually is, whether it is a byproduct of (complex?) information processing and whether it is actually computable (using classical computation). Perhaps Hugo de Garis views consciousness as just being self-aware. 

Exile438 responded that the “human brain has 100billion neurons and each connects to 10,000 other neurons, 10^11*10^4=10^15 human brain capacity estimate. Brain scanning resolution and speed of computers doubles every so often so within the next 2 to 3 decades we can simulate a brain on a computer. If we can do that it would run electronically 4million times faster then our chemical brains. This leads to singularity.”
 My response: it’s certainly a strange and exciting time to be alive – the fundamental questions that we have been wrestling with since before recorded history – questions around personal identity and what makes us what we – may be unraveled within the lifetimes of most of us here today.
