E/acc and the political compass of AI war

As I've been arguing for some time, the culture war's most important front will be about AI; that's more pleasant to me than the tacky trans vs trads content, as it returns us to the level of philosophy and positive actionable visions rather than peculiarly American signaling ick-changes, but the stakes are correspondingly higher… Anyway, Forbes has doxxed the founder of «e/acc», irreverent Twitter meme movement opposing attempts at regulation of AI development which are spearheaded by EA. Turns out he's a pretty cool guy eh.

Who Is @BasedBeffJezos, The Leader Of The Tech Elite’s ‘E/Acc’ Movement?

…At first blush, e/acc sounds a lot like Facebook’s old motto: “move fast and break things.” But Jezos also embraces more extreme ideas, borrowing concepts from “accelerationism,” which argues we should hasten the growth of technology and capitalism at the expense of nearly anything else. On X, the platform formally known as Twitter where he has 50,000 followers, Jezos has claimed that “institutions have decayed beyond the point of salvaging and that the media is a “vector for cybernetic control of culture.”

Alarmed by this extremist messaging, «the media» proceeds to… harness the power of an institution associated with the Department of Justice to deanonymize him, with the explicit aim to steer the cultural evolution around the topic:

Forbes has learned that the Jezos persona is run by a former Google quantum computing engineer named Guillaume Verdon who founded a stealth AI hardware startup Extropic in 2022. Forbes first identified Verdon as Jezos by matching details that Jezos revealed about himself to publicly available facts about Verdon. A voice analysis conducted by Catalin Grigoras, Director of the National Center for Media Forensics, compared audio recordings of Jezos and talks given by Verdon and found that it was 2,954,870 times more likely that the speaker in one recording of Jezos was Verdon than that it was any other person. Forbes is revealing his identity because we believe it to be in the public interest as Jezos’s influence grows.

That's not bad because Journalists, as observed by @TracingWoodgrains, are inherently Good:

(Revealing the name behind an anonymous account of public note is not “doxxing,” which is an often-gendered form of online harassment that reveals private information — like an address or phone number — about a person without consent and with malicious intent.)

(That's one creative approach to encouraging gender transition, I guess).

Now to be fair, this is almost certainly parallel construction narrative – many people in the SV knew Beff's real persona, and as of late he's been very loose with opsec, funding a party, selling merch and so on. Also, the forced reveal will probably help him a great deal – it's harder to dismiss the guy as some LARPing shitposter or a corporate shill pandering to VCs (or as @Tomato said, running «an incredibly boring b2b productivity software startup») when you know he's, well, this. And this too.

Forbes article itself doesn't go very hard on Beff, presenting him as a somewhat pretentious supply-side YIMBY, an ally to Marc Andreessen, Garry Tan and such; which is more true of Beff's followers than the man himself. The more potentially damaging (to his ability to draw investment) parts are casually invoking the spirit of Nick Land and his spooky brand of accelerationism (not unwarranted – «e/acc has no particular allegiance to the biological substrate for intelligence and life, in contrast to transhumanism; in order to spread to the stars, the light of consciousness/intelligence will have to be transduced to non-biological substrates» Beff says in his manifesto), and citing some professors of «communications» and «critical theory» who are just not very impressed with the whole technocapital thing. At the same time, it reminds the reader of EA's greatest moment (no not the bed nets).

Online, Beff confirms being Verdon:

I started this account as a means to spread hope, optimism, and a will to build the future, and as an outlet to share my thoughts despite to the secretive nature of my work… Around the same time as founding e/acc, I founded @Extropic_AI. A deep tech startup where we are building the ultimate substrate for Generative AI in the physical world by harnessing thermodynamic physics. Ideas simmering while inventing a this paradigm of computing definitely influenced the initial e/acc writings. I very much look forward to sharing more about our vision for the technology we are building soon. In terms of my background, as you've now learned, my main identity is @GillVerd. I used to work on special projects at the intersection of physics and AI at Alphabet, X and Google. Before this, I was a theoretical physicist working on information theory and black hole physics. Currently working on our AI Manhattan project to bring fundamentally new computing to the world with an amazing team of physics and AI geniuses, including my former TensorFlow Quantum co-founder @trevormccrt1 as CTO. Grateful every day to get to build this technology I have been dreaming of for over 8 years now with an amazing team.

And Verdon confirms the belief in Beffian doctrine:

Civilization desperately needs novel cultural and computing paradigms for us to achieve grander scope & scale and a prosperous future. I strongly believe thermodynamic physics and AI hold many of the answers we seek. As such, 18 months ago, I set out to build such cultural and computational paradigms.

I am fairly pessimistic about Extropic for reasons that should be obvious enough to people who've been monitoring the situation with DL compute startups and bottlenecks, so it may be that Beff's cultural engineering will make a greater impact than Verdon's physical one. Ironic, for one so contemptuous of wordcels.


Maturation of e/acc from a meme to a real force, if it happens (and as feared on Alignment Forum, in the wake of OpenAI coup-countercoup debacle), will be part of a larger trend, where the quasi-Masonic NGO networks of AI safetyists embed themselves in legacy institutions to procure the power of law and privileged platforms, while the broader organic culture and industry develops increasingly potent contrarian antibodies to their centralizing drive. Shortly before the doxx, two other clusters in the AI debate have been announced.

First one I'd mention is d/acc, courtesy of Vitalik Buterin; it's the closest to acceptable compromise that I've seen. It does not have many adherents yet but I expect it to become formidable because Vitalik is.

Across the board, I see far too many plans to save the world that involve giving a small group of people extreme and opaque power and hoping that they use it wisely. And so I find myself drawn to a different philosophy, one that has detailed ideas for how to deal with risks, but which seeks to create and maintain a more democratic world and tries to avoid centralization as the go-to solution to our problems. This philosophy also goes quite a bit broader than AI, and I would argue that it applies well even in worlds where AI risk concerns turn out to be largely unfounded. I will refer to this philosophy by the name of d/acc.

The "d" here can stand for many things; particularly, defensedecentralizationdemocracy and differential. First, think of it about defense, and then we can see how this ties into the other interpretations.

[…] The default path forward suggested by many of those who worry about AI essentially leads to a minimal AI world government. Near-term versions of this include a proposal for a "multinational AGI consortium" ("MAGIC"). Such a consortium, if it gets established and succeeds at its goals of creating superintelligent AI, would have a natural path to becoming a de-facto minimal world government. Longer-term, there are ideas like the "pivotal act" theory: we create an AI that performs a single one-time act which rearranges the world into a game where from that point forward humans are still in charge, but where the game board is somehow more defense-favoring and more fit for human flourishing.

The main practical issue that I see with this so far is that people don't seem to actually trust any specific governance mechanism with the power to build such a thing. This fact becomes stark when you look at the results to my recent Twitter polls, asking if people would prefer to see AI monopolized by a single entity with a decade head-start, or AI delayed by a decade for everyone… The size of each poll is small, but the polls make up for it in the uniformity of their result across a wide diversity of sources and options. In nine out of nine cases, the majority of people would rather see highly advanced AI delayed by a decade outright than be monopolized by a single group, whether it's a corporation, government or multinational body. In seven out of nine cases, delay won by at least two to one. This seems like an important fact to understand for anyone pursuing AI regulation.

[…] my experience trying to ensure "polytheism" within the Ethereum ecosystem does make me worry that this is an inherently unstable equilibrium. In Ethereum, we have intentionally tried to ensure decentralization of many parts of the stack: ensuring that there's no single codebase that controls more than half of the proof of stake network, trying to counteract the dominance of large staking pools, improving geographic decentralization, and so on. Essentially, Ethereum is actually attempting to execute on the old libertarian dream of a market-based society that uses social pressure, rather than government, as the antitrust regulator. To some extent, this has worked: the Prysm client's dominance has dropped from above 70% to under 45%. But this is not some automatic market process: it's the result of human intention and coordinated action.

[…] if we want to extrapolate this idea of human-AI cooperation further, we get to more radical conclusions**. Unless we create a world government powerful enough to detect and stop every small group of people hacking on individual GPUs with laptops, someone is going to create a superintelligent AI eventually - one that can think a thousand times faster than we can - and no combination of humans using tools with their hands is going to be able to hold its own against that. And so we need to take this idea of human-computer cooperation much deeper and further. A first natural step is brain-computer interfaces.…

etc. I mostly agree with his points. By focusing on the denial of winner-takes-all dynamics, it becomes a natural big tent proposal and it's already having effect on the similarly big tent doomer coalition, pulling anxious transhumanists away from the less efficacious luddites and discredited AI deniers.

The second one is «AI optimism» represented chiefly by Nora Belrose from Eleuther and Qiuntin Pope (whose essays contra Yud 1 and contra appeal to evolution as an intuition pump 2 I've been citing and signal-boosting for next to a year now; he's pretty good on Twitter too). Belrose is in agreement with d/acc; and in principle, I think this one is not so much a faction or a movement as the endgame to the long arc of AI doomerism initiated by Eliezer Yudkowsky, the ultimate progenitor of this community, born of the crisis of faith in Yud's and Bostrom's first-principles conjectures and entire «rationality» in light of empirical evidence. Many have tried to attack the AI doom doctrine from the outside (eg George Hotz), but only those willing to engage in the exegesis of Lesswrongian scriptures can sway educated doomers. Other actors in, or close to this group:

Optimists claim:

The last decade has shown that AI is much easier to control than many had feared. Today’s brain-inspired neural networks inherit human common sense, and their behavior can be molded to our preferences with simple, powerful algorithms. It’s no longer a question of how to control AI at all, but rather who will control it.

As optimists, we believe that AI is a tool for human empowerment, and that most people are fundamentally good. We strive for a future in which AI is distributed broadly and equitably, where each person is empowered by AIs working for them, under their own control. To this end, we support the open-source AI community, and we oppose attempts to centralize AI research in the hands of a small number of corporations in the name of “safety.” Centralization is likely to increase economic inequality and harm civil liberties, while doing little to prevent determined wrongdoers. By developing AI in the open, we’ll be able to better understand the ways in which AI can be misused and develop effective defense mechanisms.

So in terms of a political compass:

  • AI Luddites, reactionaries, job protectionists and woke ethics grifters who demand pause/stop/red tape/sinecures (bottom left)
  • plus messianic Utopian EAs who wish for a moral singleton God, and state/intelligence actors making use of them (top left)
  • vs. libertarian social-darwinist and posthumanist e/accs often aligned with American corporations and the MIC (top right?)
  • and minarchist/communalist transhumanist d/accs who try to walk the tightrope of human empowerment (bottom right?)

(Not covered: Schmidhuber, Sutton& probably Carmack as radically «misaligned» AGI successor species builders, Suleyman the statist, LeCun the Panglossian, Bengio&Hinton the naive socialists, Hassabis the vague, Legg the prophet, Tegmark the hysterical, Marcus the pooh-pooher and many others).

This compass will be more important than the default one as time goes on. Where are you on it?


As an aside: I recommend two open LLMs above all others. One is OpenHermes 2.5-7B, the other is DeepSeek-67B (33b-coder is OK too). Try them. It's not OpenAI, but it's getting closer and you don't need to depend on Altman's or Larry Summers' good graces to use them. With a laptop, you can have AI – at times approaching human level – anywhere. This is irreversible.

No, Dase, simply finding another Indian nerd with such similar personality traits is far from sufficient for me to consider him isomorphic to myself. I do not care that he loves his mother, I love mine. Certainly from your perspective you might well be indifferent between us, but I am merely me.

Like, is he closer to me than almost everyone else? Certainly. As are humans practically negligibly different in the space of All Possible Minds. Doesn't make them me.

Is that sufficient for him to be considered me? Not at all.

Leaving aside that what entities one identifies with is inherently subjective, I've proposed a reasonably robust criterion for determining that, at least to my satisfaction. You blackbox both of us, and assess response to a wide variety of relevant stimuli. If the variability between us is within acceptable parameters, such as being less than the variability seen in the biological me after a nap or when I took the test 2 years ago, then that system is close enough to count as including a copy of "me".

This accounts for. even mind uploads, hence the blackboxing, I don't particularly privilege my biological form, though you could do a DNA test and MRI if you really prefer to.

It might well count an emulation of me within a wider system, say a Superintelligence, but that's a feature and not a bug. That component, if it can be isolated, counts as me, leaving aside more practical concerns like what degree of power it has in the ensemble.

Moreover, if you get brain damage or dementia, your hardware and computational divergences will skyrocket, but you will insist on being a continuous (if diminished) person, and me and him will agree! It

I am tolerant of minor performance fluctuations, but a sufficient amount of brain damage or dementia? Then I consider myself gone, in most of the aspects I care about, even if the system is physically and temporally contiguous.

The primary reason I might still value further existence is-

  1. Hopes that the damage can be mitigated with future advances, if not losslessly.

  2. Until the damage gets really bad, that poor soul is still closer to me than anyone else.

But if it gets bad enough, I assure you I consider the core construct to be dead.

I am, incidentally, immune to this issue because I do not believe in computationalism or substrate independence

I have always found this a peculiar view, and certainly I haven't seen any particular reason to assume a difference in internal qualia because of a difference in substrate, as long as the algorithms deriving it are interchangeable in terms of inputs and outputs.

Is it possible? I can't rule it out. But the bulk of my probability mass is against it.

If you have a convincing argument otherwise, I'm curious to hear it.

I will reject this conclusion until the time I have an opportunity to get much smarter and reexamine the topic or perhaps design some fix for this pervasive mental defect

My current approach to modeling myself has enough practical ramification that I will accept it on an operational basis. Certainly I would love to re-examine it in more detail when it becomes more relevant, such as if I'm contemplating a mind upload and am either smarter myself or have an ASI to answer my questions.

But it reduces to normality for almost every situation I can expect to encounter today, so it's hardly the most pressing matter.

You are performing more or less identical calculations, on very similar hardware, to a near-identical result, and if you one day woke up, Zhuangzi style, to be him, your own life story a mere what-if distribution shift quickly fading into the morning air – I bet you would have only felt a tiny pinprick of nostalgia before going on with his business, not some profound identity crisis.

Believe it or not, I have often imagined, idly, having my consciousness magically transferred into the shell of someone I envy. The conclusion I have drawn is that there are some aspects of my life I would happily discard, if he's an accomplished banker (and I retain his skills and memories), I would happily not attempt to pursue medicine. But I would still prefer my original parents or kin, and attempt to convey my conundrum to them, likely by divulging privileged information only known to the original me.

If my "original" is still around? Inform him and work with him. I might be suitably disposed to help the "replaced" persons family and friends, but largely because they're predisposed to help me, assuming they don't know the truth.

After all, I expect and wish to continue preferring the consciousnesses descended from my own current kin even after we've all become post-biological, a mere swap of DNA carrier, while extremely queer and not entirely desirable, represents no major impediment.*

*The primary reason I am attached to my genes is because they code for people and personalities similar to mine. I couldn't care less about most phenotypic traits.

I think your problem is typical for Indians (and most other non-WEIRDs and non-Japanese, to be fair, including my people… but worse so in Indians): you have no taste, not even the notion of "taste", to you it's probably an arbitrary set of markers of one's social milieu rather than some relatively lawful intuition. So you settle for mediocre half-baked ideas easily as long as they seem "cool" or "practical", and – physics of consciousness being currently impractical – coolness is a much simpler function than tastefulness. I am not sure how or why this works. Maybe @2rafa can explain better; maybe she'll opine I'm wrong and it is in fact purely about social markers. (Also interested in the input of @Southkraut and @ArjinFerman). In any case, it's exasperating to debate such uncertain grounds without the recourse to "this is just ugly" when it patently is.

I've proposed a reasonably robust criterion for determining that, at least to my satisfaction. You blackbox both of us, and assess response to a wide variety of relevant stimuli. If the variability between us is within acceptable parameters, such as being less than the variability seen in the biological me after a nap or when I took the test 2 years ago, then that system is close enough to count as including a copy of "me".

Oh yeah? So which is it, a nap or a 2-year time span? Are you sure you can, really, practically can, define a rubric such that no other person I find comes closer to the first data point in the latter case? Sure you can do this without including password-recovery-tier questions, the answers to which are entirely value-free, RNG-produced token sequences, in no way corresponding to actually unique specifics of your inner conscious computation?

It's only reasonably robust from the viewpoint of a time-constrained clerk – or an archetypal redditor. As stated, I claim that you might well fail this test under realistic and legitimate conditions of dropping cheat items; and then, if I decide, in this contrived scenario, that the non-self-made-human is to be sent to the garbage compressor, you will very loudly (and rightfully) complain, not showing any "satisfaction" whatsoever. The only reason you propose it is your confidence that this does not matter in actuality – which it admittedly does not. And in any case, you do not need to optimize for a le scientific, robust, replicable, third-person-convincing etc. identity test. Rather, you need to think about what it is you are trying to achieve by clinging to the idea that a cluster of behavioral correlates an observer can identify will carry on your mind – just gotta make it dense enough that in practice you won't be confused for another naturally occurring person.

certainly I haven't seen any particular reason to assume a difference in internal qualia because of a difference in substrate, as long as the algorithms deriving it are interchangeable in terms of inputs and outputs.

Fair enough.

But I would still prefer my original parents or kin, and attempt to convey my conundrum to them, likely by divulging privileged information only known to the original me.

I'll trust you on this even though I strongly suspect this would depend on the intensity of original memories vs. the recovered set.

I have to say calling someone an archetypal redditor is a very low blow. As is the comic, which I think we could all pull apart in a matter of seconds. Off the top of my head, what if you remove the screen and show the human and dog that the woofing isn't a real dog? Since when did anyone in this long and complex discussion say that sound was the only mechanism people/canines could use to recognize authenticity? The whole thing you're talking about is how complex and multifactorial identity-recognition is. It's irrelevant at best.

Since when did self-made say he'd be happy for you to send someone very like him (perhaps so similar as to be a soulmate or a best friend) to the garbage compressor because he wasn't so identical as to be effectively the same person? How can you think he would be forced to that conclusion, based on the premises he's established, which explicitly include weighting highly those like himself?

@self_made_human isn't treating you with that kind of disrespect.

As for substrate independence, we should be thinking about truth rather than beauty. How can it be impossible, in principle, to replace individual neurons one by one with a computerized equivalent such that normal function is preserved and the patient is conscious throughout the whole operation? Do you believe that there's some advanced quantum mechanics in our heads that's integral to our identity that simply cannot be emulated with machinery, no matter how advanced our technology? How can the human brain be so sophisticated, it was thrown together with incredible resource constraints on the savannah.

And since when did people agree that dementia patients were continuous with their original selves? They're not, I've observed this first-hand. Past a certain point there's a qualitative change. I can't tell you when or where, just like it's hard to say how many bricks a house can lose before it collapses or is unliveable.

As is the comic, which I think we could all pull apart in a matter of seconds. Off the top of my head, what if you remove the screen and show the human and dog that the woofing isn't a real dog? Since when did anyone in this long and complex discussion say that sound was the only mechanism people/canines could use to recognize authenticity? The whole thing you're talking about is how complex and multifactorial identity-recognition is. It's irrelevant at best.

The idea of "multifactorial identity-recognition" is irrelevant for the purpose of understanding the issue of consciousness-continuity of a subject. But really, after such arguments, what more can be said? Truly, you can also look at the dog! Oh wow, the argument against black box analysis is pulled apart!

Since when did self-made say he'd be happy for you to send someone very like him (perhaps so similar as to be a soulmate or a best friend) to the garbage compressor because he wasn't so identical as to be effectively the same person?

Morality is irrelevant for this counterfactual; this is only dependent on the baseline self-preservation and endorsement of the notion that black box suffices.

As for substrate independence, we should be thinking about truth rather than beauty.

There is no meaningful difference between truth and beauty with regard to this question.

Poor taste is irredeemable, and you're one of the worst in this respect here, by the way.

How can it be impossible, in principle, to replace individual neurons one by one with a computerized equivalent such that normal function is preserved and the patient is conscious throughout the whole operation?

Following Moravec, I think this is possible, though I am not sure which aspects of neuronal computations and their implementations are relevant for this procedure (eg how to deal with LFPs). I reject the sloppy bugman idea that you can get from this to "just boot up a machine simulating access to a copy of my memories bro". Indeed, if you didn't have such poor taste, you'd have been able to see the difference, and also why you are making this argument and not the direct defense of computationalism.

Do you believe that there's some advanced quantum mechanics in our heads

Now that's what I call real disrespect lol. It's okay though.

Now that's what I call real disrespect lol. It's okay though.

I think that line was crossed when you claimed that Indians lack "taste", or at least I do.

Believe me, I like you and enjoy your commentary, or else my patience would have been exhausted a good while back.

As I've repeatedly invited you to demonstrate, give one good reason for why substrate independence can't work, especially if we can simulate neurons at the molecular level (they're not beyond the laws of physics, if beyond compute budgets), or at least in aggregation by modeling their firing patterns with ML "neurons", which can replicate their behavior, even if it takes somewhere around a thousand of those per biological one.

Before we potentially get bogged down in terms of implementation or the sheer difficulty of the task, which I happily grant is colossal, why can't it work in principle?

Even positing Penrosian claims that the quantum dynamics of microtubules are somehow remotely relevant in modeling such a stochastic environment, those can simulated too.

What exactly isn't being preserved in such a transition, that remains conserved when almost all of the individual atoms in your body have and will be endlessly cycled and replaced by equivalent counterparts through the course of your life?

If you concede that point, then I have little to know interest in arguing whether you should value such an entity forked from yourself. Feel free not to, or do things as dumb as Hansonian Ems I suppose. I'm content in knowing that, if nothing else, such copies will heavily weight the preferences and wellbeing of SMH Mk1, regardless of everything. My standards, while eminently sensible, are my own.

Your sense of aesthetics counts for about zilch, not when you do a terrible job of presenting a compelling case for them.

As @RandomRanger can see, you've been high on aesthetics, nothing else. I'm not mad, I'm just disappointed, I expected better from you.

It really is fine, I would never be able to care about such offenses (barring brain damage), or, hopefully, even intentional offenses from people like you or Ranger. I just dislike the quantum microtubules thing – it's tasteless too, after all; just adding a layer of pseudo-empirical woo to postpone responding to a relatively compact philosophical challenge.

give one good reason for why substrate independence can't work, especially if we can simulate neurons at the molecular level

I do not have to give you any reasons because your position, in its decisive dimensions, has zero empirical content, it is just metaphysics – of a tool who has first-person experience but cognitively is conditioned to process himself through the master's pragmatic point of view. Well, that and geeky masturbation about (irrelevant, surmountable) difficulties of computing this or that. My metaphysics is the opposite, I start with asking for a reason to believe that computational equivalence even matters, because this is about me, not about some external function. I exist for myself. Do you exist for yourself? What does it mean to exist for oneself? Can you even conceive, in a purely hypothetical way, of the possibility of a distinction between you existing for yourself, and "something that simulates you" existing for myself, but not for itself? Not a strict p-zombie, perhaps, but something whose internal experience is different from the experience it computes, in a way that does not remotely hold for your current implementation? In my experience there is a qualitative and insurmountable difference between people who can and cannot, so I'd rather not invest into debating you, and just have fun the way I feel like.

You started with outsider-oriented rubrics to test similarity between two black-box behavioral generators compared to a years-old exemplar (in x years every molecule changes etc. etc. as you say, and I just call bullshit on the idea that you're more like yourself in 70 years than like another similar guy of your age, but anyway it's irrelevant); then retreated to increasingly fine-grained circuit equivalence in white boxes; now you talk about molecular simulation which will necessarily, overwhelmingly capture neurocomputationally redundant content. This is commendable: you at least have some remains of a normal-person intuition that your consciousness literally is your brain and not some equivalent of it with regard to some interface or observer. But you cannot come to grips with this intuition or wonder if it corresponds to something coherent.

Some can. In the words of Christof Koch, whose book The Feeling of Life Itself: Why Consciousness Is Widespread But Can’t Be Computed I've mentioned a few times: «The maximally irreducible cause-effect power of real physical computers is tiny and independent of the software running on the computer… Two systems can be functionally equivalent, they can compute the same input–output function, but they don’t share the same intrinsic cause-effect form. A computer of figure 13.3 doesn’t exist intrinsically, while the circuit that is being simulated does. That is, they both do the same thing, but only one is for itself. […] Consciousness is not a clever algorithm. Its beating heart is causal power upon itself, not computation. And here’s the rub: causal power, the ability to influence oneself or others, cannot be simulated. Not now, nor in the future. It has to be built into the physics of the system… This is true even if the simulation would satisfy the most stringent demands of a microfunctionalist. Fast forward a few decades into the future when biophysically and anatomically accurate whole-human-brain emulation technology—of the sort discussed in the previous chapter—can run in real time on computers.13 Such a simulation will mimic the synaptic and neuronal events that occur when somebody sees a face or hears a voice. Its simulated behavior (for instance, for the sort of experiments outlined in fig. 2.1) will be indistinguishable from those of a human. But as long as the computer simulating this brain resembles in its architecture the von Neumann machine outlined in figure 13.3, it won’t see an image; it won’t hear a voice inside its circuitry; it won’t experience anything. It is nothing but clever programming. Fake consciousness—pretending by imitating people at the biophysical level».

A pragmatist says: what should we care about that! My causal power is that which… something something inputs-outputs, so long as the function describing this transformation is the same, surely it is preserved! A pragmatist more invested in the conversation would add: why, I've cracked open the book, and it seems this all depends on some weird axioms in chapter 7 and 8, kooky stuff like consciousness exists intrinsically, for itself, without an observer, about why accept them and not a much more convenient (or rather, observer-oriented) approach? Also, why not Dust Theory?

Koch's specific technical justifications have to do with IIT, which is substantially flawed. In time, a better theory will be developed. But I don't think one needs a theory to just see how confused the metaphyics of a Tool, of someone who cannot throw out the entire baggage of External Observers, is. One only needs taste. I do not hope nor intend to rectify your taste, you're free to revel in it, just as I am free to think it repulsive.

Can you even conceive, in a purely hypothetical way, of the possibility of a distinction between you existing for yourself, and "something that simulates you" existing for myself, but not for itself?

If there is an entity that can simulate me with near perfect accuracy, I see no route through which it can achieve that without having an analogue of me inside it. Even if it's, say, an AGI that's attempting to mimic my behavior in an attempt to fool me into doing something I'd rather not, somewhere inside that tangled mass of computation is something faithfully recreating my cognitive structure.

That's an unavoidable consequence of consciousness being computational, there's no cheat code or hack to get it without running the numbers. I would obviously discount my approval of such entities that only have me as a tiny, not particularly authoritative part, in much the same manner I would prefer not to be in prison mumbling lines at gunpoint. Even something along the lines of a LUT, like a Chinese Room, necessitates someone, at some point performing computation and then saving it for lookup. You can play card tricks with it, shuffle it around, you can't get rid of it.

Can I conceive of such an entity? Sure, humans can imagine plenty of things that don't exist or never can exist, such as an integer hiding between 7 and 8 in base 10. It's when you notice the obvious incongruencies from that kind of degenerate assumption that you are forced to reconsider, tantamount to a proof by contradiction.

I don't think it's remotely likely or plausible, holding out only a tiny dollop of epistemic humility when neuroscience hasn't been solved.

Keep in mind I'm not quite sure what you mean by that quote and I'm responding to my best attempt to interpret it.

Not a strict p-zombie, perhaps, but something whose internal experience is different from the experience it computes, in a way that does not remotely hold for your current implementation?

I think p-zombies are incoherent, and that it's likely impossible to pull what you propose off. That's != inconceivable, I both conceive of it and dismiss it. If you're having trouble with differentiating a potential p-zombie from the real deal, well that sucks, you need to crack it open and see how it works, and once again my proposed system of tests is intended to be so fine grained that there's no way to trick it that's not simply running a high fidelity simulation in one form or another. In other words, using the AGI analogy, the greater mind might have qualia entirely different from a subunit that's emulating me. I'm still being emulated somewhere in there. What of it? I'm in a system that includes the room I'm lying in. I'm sure if you want to torture ideas of qualia to ask what that might look like for a system that included the other people in the house, you can see it's the same thing.

I do not have to give you any reasons because your position, in its decisive dimensions, has zero empirical content, it is just metaphysics

Well, at least we both acknowledge that. If you think my position isn't violating any law of computation, information theory or physics, then it can well boil down to Fundamental Values Differences in the ramifications of such.

Two systems can be functionally equivalent, they can compute the same input–output function, but they don’t share the same intrinsic cause-effect form.

When an abacus and a graphing calculator add two numbers together, they, if operating correctly, provide the same output for the same input. They're both implementations of Turing Machines after all.

One can well prefer one particular implementation for practical consideration. As possible as it is to run GPT-4 in a system of a billion diligent monks moving abacus beads, it's a bad idea in practise.

Since I am more concerned with establishing an isomorphic relationship, in the same manner a TI-82 and an abacus are fundamentally isomorphic when it comes to doing arithmetic, a digital upload of me has many robust advantages over my biological form, even after enormous amounts of augmentation. Biology is great within its particular constraints, not when energy budgets can become notable on the Kardashev scale.

That is, they both do the same thing, but only one is for itself. […] Consciousness is not a clever algorithm. Its beating heart is causal power upon itself, not computation. And here’s the rub: causal power, the ability to influence oneself or others, cannot be simulated. Not now, nor in the future. It has to be built into the physics of the system

This is far from obvious to me, I can't parse this as anything but a non sequitur.

Why can't you simulate "causal power"? Just hook it up to an output that operates in the Real World™.

A entity locked into a digital simulation has less "causal power" than one that isn't, certainly, but why is it ending up in such a state?

Consciousness seems to me like it can clearly be built into the physics of transistors on a chip when it can run on electrochemical spikes in wet tissue. How is that any less physical?

It can be nested arbitrarily deep, which isn't feasible in biology as we know it, but there's nothing stopping you from running it bare-metal with the same degree of differentiation from external reality as consciousness in-vivo.

But as long as the computer simulating this brain resembles in its architecture the von Neumann machine outlined in figure 13.3, it won’t see an image; it won’t hear a voice inside its circuitry; it won’t experience anything. It is nothing but clever programming. Fake consciousness—pretending by imitating people at the biophysical level

The laws of physics can be simulated with arbitrary precision on a computer with a Von Neumann architecture.

The human brain is physical.

Ergo I see no reason that this distinction matters.

As for Dust Theory, it's been a while since I read half of Permutation City. But I fail to see how it changes anything, my subjective consciousness wouldn't notice if it was being run on abacuses, meat or a supercomputer, or asynchronously. It doesn't track objective time. Besides, I sleep and don't lose sleep over that necessity, the strict linear passage of time is of no consequence to me, as long as it doesn't impede my ability to instantiate my goals and desires.

Relevant XKCD

https://xkcd.com/505/

You started with outsider-oriented rubrics to test similarity between two black-box behavioral generators compared to a years-old exemplar (in x years every molecule changes etc. etc. as you say, and I just call bullshit on the idea that you're more like yourself in 70 years than like another similar guy of your age, but anyway it's irrelevant); then retreated to increasingly fine-grained circuit equivalence in white boxes

There is no "retreat" involved. A test that has meaningful results for external observers has plenty of utility in itself. What if I'm dead and being revived from a plastinated brain? If they have a record of what an objective battery showed prior to brain death, they can have robust confidence that the data transmission wasn't too lossy.

I am merely being exhaustive in covering all my bases, be it finetuning an LLM on me, different fidelities of brain scans and more esoteric technology yet.

The blackbox approach is a fallback for when a white box isn't available, or the results aren't interpretable, in the same way you could train an LLM on me and neither of us could perform mechanistic interpretability on it, being forced to rely on outputs.

Hmm.. @faul_sname, you didn't get an invite to the Transhumanist Rumble, it got lost in the mental mail. Come get your comments in while the thread isn't entirely mouldy! Certainly I expect you to be better informed than me, and even potentially Dase.

I've written a bunch, and deleted (your response to the issue of causal power was decisive). The long and short of it is that, being who you are, you cannot see the problem with Dust Theory, and therefore you do not need mind uploading – in the Platonic space of all possibilities, there must exist a Turing machine which will interpret, with respect to some hypothetical decoding software at least, the bits of your rotting and scattering corpse as a computation of a happy ascended SMH in a Kardashev IV utopia. That this machine is not physically assembled seems to be no obstacle to your value system and metaphysics which deny that physical systems matter at all; all that matters, according to you, is ultimate constructibility of a computation. From the Dust Theory perspective, all conceivable agents have infinite opportunity to 'instantiate their goals and desires'. Seeing that, I would ask and indeed try to prevent you from wasting the valuable (for me, a finite physical being) negentropy budget on frivolous and wholly unnecessary locally computed and human-specified simulations which only add an infinitesimal fraction of your preferred computations to the mix.

I do not see why the existential of potential entities that "emulate" me in such a theoretical fashion precludes me from caring about the more prosaic/physical instantiations. My values do not particularly care that, for another example, I could potentially be reincarnated in a Boltzmann Brain, which, if I understand the physics involved, is nigh inevitable in an eternal universe.

Sure, that's nice to have. I also prefer more concrete representations of myself running around in the universe I am confident exists. Every decision theory I am aware of breaks down (or at least becomes indifferent between outcomes) when confronted with such infinities, but I am tentatively willing to ascribe that as a flaw in said decision theories rather than a reason to descend into apathetic nihilism.

As a matter of fact, whatever goes on in "Platonic space" matters just about nothing as far as I'm concerned. That's true for every computable entity or worldstate, hence it adds no reason to privilege or disprivilege my bumblings in more physical environs.

More comments

I'm definitely not more informed than Dase here. Anyway I specified in my other comment an example of a quite simple computational system that almost certainly contains a faithful representation of you.

you didn't get an invite to the Transhumanist Rumble

Sounds fun but unfortunately my weak biological substrate requires regular periods of inactivity to maintain optimum performance. And one of those periods is scheduled for now.

Undoubtedly, I'm sure there's a copy of me, with as much metadata as you please lurking in pi itself.

You're not going to get such a degenerate system to replicate me before blackholes start evaporating, so I'll stick to my rough and ready operational definition for now heh. After all, my proposal certainly implies active computation being performed, a backup in cold storage, while not worthless, isn't what it's meant to be handling, not until you can spin it up at least!

you're one of the worst in this respect here, by the way

Grow up. Your argument is based entirely on feels, on smelling an aura of 'bugman' on uploading, not the factual basis. This is just an esoteric version of those right-wing twitter anons who smell 'bugman' on AI and denounce it as mere linear algebra, pattern-matching autocorrect with media buzz. They get a bad vibe and then look for reasons to disdain it, thinking emotionally rather than logically.

'Bad taste' is a cope. Reality doesn't have to be realistic, let alone tasteful or aesthetically pleasing (especially not to you in particular). The arrogance needed to say that your personal opinions on aesthetics are equivalent to physical/technical truth is unfathomable to me. If you were some peerless world genius in the field of AI, neuroscience and HBI then maybe you could get away with this. But you're not.

If you can gradually emulate a conscious being, you can also copy-paste it. There's nothing sophisticated about this concept.

Call a bugman a bugman and see how he recoils etc.

As I've said already, "sophistication" is not what is needed to see your failures here. Specifically, the distinction between copy-pasting and transposition. Indeed, this is very trivial, children get it, until they are gaslit with sloppy computationalist analogies.

Specifically, the distinction between copy-pasting and transposition.

There is a distinction and it's totally irrelevant to what I'm saying. Use reading comprehension.

Poor taste is irredeemable, and you're one of the worst in this respect here, by the way.

Oh Christ. I like you man, but sometimes I worry what will happen if you're the first to ascend into the Singularity. My tastes aren't that sophisticated either!

You're fine in my book. And 'sophistication' has very little to do with what I take to be their failures in taste.

That said, sadly you wouldn't have had much to worry in any case; and I think people most likely to ascend first have next to no taste.

I doubt that the conditions would align for any one single entity to solely ascend and create a unipolar post-Singularity world, but I also haven’t read that deeply into such debates. Have there been previous conversations around this on TheMotte?

As for substrate independence, we should be thinking about truth rather than beauty. How can it be impossible, in principle, to replace individual neurons one by one with a computerized equivalent such that normal function is preserved and the patient is conscious throughout the whole operation? Do you believe that there's some advanced quantum mechanics in our heads that's integral to our identity that simply cannot be emulated with machinery, no matter how advanced our technology?

That's not the argument being made though. The argument is "a copy of my mind out on Mars in a separate body is still effectively me". That's what I disagree with.

Also interested in the input of @Southkraut and @ArjinFerman

I have no opinion on these topics of qualia and whatnot. It's far above my pseud paygrade. A hypothetical faithful copy of my responses to stimuli would hypothetically be me for everyone else involved. As for myself - I guess a continuous transfer from the biological to the digital or another body might preserve my sense of identity, but would also change me to some extent that depends on the particulars of the mechanism. Is that then me, or someone else? It doesn't matter until this actually happens to someone.

IMO mind uploading, consciousness copying, immortality, cryogenics, singularity etc. are all wishful thinking, clung to by people who attempt to distract themselves from their mortality. Thinking of yourself as an immortal-in-waiting then makes the comparably short natural lifespan seem even shorter, driving those people to believe even harder in the certainty of their imminent apotheosis.

The truth is that we're all going to die, most of us sooner than we'd like, and it's going to be fairly horrible for almost everyone involved, as it always has been.

(Also interested in the input of Southkraut and ArjinFerman).

I've always had very rigid opinions on the subject, and the only way I can "steelman" his idea is by assuming I must be misunderstanding what he means by the copy being him. Like I said, the only way it makes the slightest bit of sense to me, is if he's looking at it the same way one might look at being survived by their children. Bringing up another Indian nerd isn't even that far off the mark. When people can't have children they're prone to becoming mentors so a part of them can live on through the impact they've made on others. From there, I suppose I can understand building some sort of Pinocchio that will share your memories and quirks of personality.

The problems is that when I look at @self_made_human's actual words, the above seems like blatant sane-washing. He seems to believe any such copy will actually be him in some non-symbolic sense, which seems rather absurd. Maybe you can argue it from some cosmic-nihilist bird's eye view, but, as you pointed out, it's hard to defend from a "help! you've put the wrong one in the garbage compressor!" perspective.

He seems to believe any such copy will actually be him in some non-symbolic sense, which seems rather absurd.

I do believe it will be "me" to my desired level of satisfaction, and far better at the job than the currently available options of having kids, promulgation one's cultural or ethical values, or even a biological clone. To the point that if such a being appeared before me, it can have half my money no strings attached.

As for it being absurd to you? That's simply irrelevant to me. I don't think you agree with Dase about our other transhumanist predilections, so I don't see it mattering for the purposes of the debate.

I do believe it will be "me" to my desired level of satisfaction, and far better at the job than the currently available options of having kids, promulgation one's cultural or ethical values, or even a biological clone.

So just to be sure I understand you: you don't actually think it will be *you*? We are simply discussing your potential descendants. Far better, by your estimation, than any other descendant we can currently come up with, but still just a descendant?

To the point that if such a being appeared before me, it can have half my money no strings attached.

You gotta move the the US. Someone might actually be tempted to train an LLM on your output, to get a chunk of an American doctor's salary.

you don't actually think it will be you?

"you" is, to put it gently, a vague word, and certainly well out of its depth when talking about such hypothetical advances. But I would have no qualms about talking about it as "me", in much the same manner I can happily do so when talking about "me" 10 years ago or in another 50.

I wouldn't call a hypothetical monozygotic twin "me" today, or a fresh clone of myself.

Far better, by your estimation, than any other descendant we can currently come up with, but still just a descendant?

Far better in terms of replication of consciousness? Certainly. I'm sure that if you were being sufficiently imaginative in terms of "what we can currently come up with", you might find something or someone I like more than myself, but that's not the point in contention. I might end up valuing my child's life more than my own, as is common for parents. Ask me when I have one I guess.

But a child is not me, even if I'd potentially give them half my money if necessary, or more, and at least half my name.

You gotta move the the US. Someone might actually be tempted to train an LLM on your output, to get a chunk of an American doctor's salary.

If you go through the comment chain, I have far stricter standards than merely being swayed by a fine-tuned LLM. I do not expect that to me remotely sufficient.

"you" is, to put it gently, a vague word, and certainly well out of its depth when talking about such hypothetical advances.

I disagree vehemently. In my opinion, no matter the advances, *I* will always immediately be able to tell if *I* ended up in the trash compactor, rather than a copy.

This is, again, where I have no choice but accuse myself of sane-washing your ideas. I could sort of see where you're coming from, if we're only discussing descendants, I can even understand, even as I disagree with it, putting a premium value on the artificial copies of yourself over the currently available descendants. But claiming there is any vagueness in the concept of *me* is coco bananas.

Far better in terms of replication of consciousness? Certainly.

Yeah, but I don't get why I should care about replicating consciousness. It's still just a copy.

If you go through the comment chain, I have far stricter standards than merely being swayed by a fine-tuned LLM. I do not expect that to me remotely sufficient.

I thought I did see your criteria, I was going by this:

I've proposed a reasonably robust criterion for determining that, at least to my satisfaction. You blackbox both of us, and assess response to a wide variety of relevant stimuli. If the variability between us is within acceptable parameters, such as being less than the variability seen in the biological me after a nap or when I took the test 2 years ago, then that system is close enough to count as including a copy of "me".

I don't see anything here that wouldn't be fundamentally replicable by an LLM.

I don't think a text interface suffices, as @2rafa once suggested, it might be possible to finetune an LLM on all the text I or anyone else has ever written, such that someone who is only interacting with us via text could be fooled indefinitely.

There you go.

At the very least my hypothetical test of replication of consciousness would require things that no LLM today, no matter how multimodal, could pull off.

I don't think a text interface suffices, as @2rafa once suggested, it might be possible to finetune an LLM on all the text I or anyone else has ever written, such that someone who is only interacting with us via text could be fooled indefinitely.

My point is that I expect both of us to have the same/indistinguishable internal qualia, so for a sufficiently high fidelity copy, I'm agnostic as to who gets trashed, not that I want that for either of us if it can be helped.

From the inside, we can't tell the difference.

It's still just a copy.

"Just". I think we have to agree to disagree on what the ramifications of a copy of either of us existing would entail.

At the very least my hypothetical test of replication of consciousness would require things that no LLM today, no matter how multimodal, could pull off.

Am I going crazy? I swear I've seen people upload screenshots and photos to ChatGPT and have it respond to their content. Is it that any AI that handles more than text input is technically no longer just a "language model"? That sounds like playing semantics.

From the inside, we can't tell the difference.

This might be the fundamental disagreement. From the outside we may not tell the difference. From the inside the difference is immediately obvious.

"Just". I think we have to agree to disagree on what the ramifications of a copy of either of us existing would entail.

Yeah. Here's hoping Roko's Basilisk tries to threaten me instead of you.

More comments

I think your problem is typical for Indians (and most other non-WEIRDs and non-Japanese, to be fair, including my people… but worse so in Indians): you have no taste, not even the notion of "taste", to you it's probably an arbitrary set of markers of one's social milieu rather than some relatively lawful intuition. So you settle for mediocre half-baked ideas easily as long as they seem "cool" or "practical", and – physics of consciousness being currently impractical – coolness is a much simpler function than tastefulness.

I sincerely fail to see what taste has to do with any of this.

I will note that my conception of replication of personality/consciousness has plenty of backers in WEIRD transhumanist circles, almost certainly any of the sizeable number of them who think mind uploading is a valid replication of theirs.

In any case, it's exasperating to debate such uncertain grounds without the recourse to "this is just ugly" when it patently is.

I can hardly stop you from using whatever form of argumentation you want in a debate, just know that appeals to aesthetics will do nothing, at best, in convincing me of your point.

Oh yeah? So which is it, a nap or a 2-year time span?

The smaller the divergence, the better, but once again, as a purely operational standard open to revision, I would accept any entity that has the same degree of inter-test variability has SMH from the age of 19 to about the age at which cognitive decline kicks in earnest, maybe 70. That accounts for about the period of time my personality and interests largely crystallized, to where I will simply become dumber and more forgetful, barring medical advances. Oh, and no severe illnesses with permanent neurological decline, for obvious reasons.

These are hardly strict cutoffs for entities I care for more than the norm, I would certainly value 7 yo or 90 yo me more than any other human alive, who isn't me-now. If someone handed me a baby clone, I'd certainly do my best to raise it as I'd have wished to be raised.

Are you sure you can, really, practically can, define a rubric such that no other person I find comes closer to the first data point in the latter case?

Yes. Presumably restricting the set of candidates to biological baseline humans living today.

If you wish to attempt this, go ahead and perform stylometry on my writings, and find one person whose writings I can't distinguish from my own with a large corpus of text. Using a finetuned LLM to generate it is forbidden, because my idealized test would consider far more than textual artifacts. I will happily concede the case if you manage the former, because I expect you'd fail miserably.

Sure you can do this without including password-recovery-tier questions, the answers to which are entirely value-free, RNG-produced token sequences, in no way corresponding to actually unique specifics of your inner conscious computation?

If it's not pure rhetoric, do you really think the battery of tests I propose are anywhere near "password recovery tier"?

I'm talking simulation of a virtual environment beyond baseline sensory discrimination with blinding, a massive battery of psychometrics and behavioral experiments, ideally circuit level analysis of neuroarchitecture. The blackboxing is purely for the case where we can't interpret the neuroarchitecture, or for proving the point where I believe in substrate indepence.

If I had a person show up to, in the flesh and blood, who claimed to be a mental copy of me, I am confident that I could discriminate the truth of that proposition to a great degree of confidence, not that my current understanding of the necessary advances in biology, computational and isekai-implementation wouldn't have me concerned someone/something was fucking with me. But that's hardly the most robust metric, hence the proposal for something that would satisfy me beyond reasonable doubt.

Fair enough.

Funny. Not remotely edifying.

I'll trust you on this even though I strongly suspect this would depend on the intensity of original memories vs. the recovered set.

I am agnostic on whether a total replacement of memories would violate much of the replication of the parts of consciousness I care about. Taken arbitrarily far? Yes. I doubt an entity based off me but only possessing memories of being tortured for a quadrillion years is anything I'd identify with.

If I suddenly became amnestic, I'd consider it a severe blow, but not to the extent I'd consider myself dead, assuming I retained skills and knowledge.

To make it clear, this is not a binary process, how could it be? The ideal entity for the purposes of duplication has has 0% variability from me, the limit of acceptability is somewhere well before someone currently existing as a separate biological person, even with 7 billion such people to sample from. I do not expect any of them to ever overlap in the same volume of mind space I've mapped in my trajectory from birth to death, not unless they were intentionally forked.

if I decide, in this contrived scenario, that the non-self-made-human is to be sent to the garbage compressor, you will very loudly (and rightfully) complain, not showing any "satisfaction" whatsoever

I object to either of us being sent to the garbage compressor. To the extent that I think having more high fidelity copies of me around is a good thing (hardly the most good thing, the marginal value becomes close to infinite when it's 1 vs 0, and then drops when there's a sufficient number to probabilistically make it to Heat Death), I am opposed to that number being decreased unless strictly necessary.

If the only means of transport available to me was a Star Trek transporter that disassembled and reassembled a copy of me at the atomic level, you best believe I'm auditing the process and comparing it to known test constructs to make sure the fidelity is as high as needed.

If it's necessary? Sure. Say I'm about to die right now and the only available route is a destructive, only partially validated brain uploading tech, or even worse, desperately uploading every aspect of my biometric or stylometric output as training data for an AI meant to replicate me. Or if I've been cryopreserved and need to be reanimated. All of them are far preferable to utter information theoretic death. It's a minor consolation to me that things I've written and described have ended up in the training set of future LLMs and other AI.

If none of that applies, then I will resist, violently, an attempt to murder me or my clones.

Well, if we're summoning fellow transhumanists to the brawl of the decade, I call forth:

@RandomRanger @curious_straight_ca

And probably a bunch of others, not that I can remember their names offhand.

I'm certainly with you as well! This has been a frustrating debate to follow if not only for the satisfaction of reading someone else express my views on continuity of self identity almost exactly. I wish people would not sneer as much, but I suppose as an uploadist, one needs to have the humility to recognize their view is the more peculiar one.

I wouldn't mind all that much if it wasn't coming from Dase, who I am on decent terms with, and more importantly, expect better from. If you can't make a convincing argument that isn't purely from aesthetics, GGWP.

At any rate, I have little vested interest in convincing others of the validity of such claims, more that my approach is internally consistent and doesn't violate the known laws of physics. Everything after that becomes a question about your values system, such as if you should care that the version of you inside a computer lacks rights.

One massive bonus of our approach is that we're looking out for each other, in the sense that I expect an upload of myself to continue having a great deal of empathy and altruism (? does the word even apply) for the poor bastard stuck in the meat suit, assuming the latter can't be fortified to respectable posthuman standards itself. If these guys do so, well they better pray their selfishness doesn't bite them in the ass.

After all, I recognize that a successful, non-destructive mind upload still leaves me (or at least the original copy) behind, potentially doomed by biology. I still prefer non-destructive uploading, preferably one that maintains continuity of consciousness, but if that's not an option when I'm about to die, then so be it, that's grossly superior as a form of immortality when compared to having kids or leaving my writings behind.

Have you guys read Permutation City? It was a highly enjoyable read for me, and explores a variety of scenarios of simulated minds and their experiential identity.

I confess to only getting halfway through it and then getting distracted, but it was certainly interesting while I was reading it. I've certainly grabbed a few aspects, such as emulations running slower than biological humans (unless you pay out the arse) for my own book.
