This assessment of the timeline is quite telling. If supersonic flight posed an existential threat to humanity, we certainly should have been thinking about how to mitigate it in 1925.
The fact that you make insinuations about what I think is pretty aggressive and terrible similarly, this forum ought to have better manners than that when writing replies to complete strangers. Not everyone who has a different opinion is some crypto conspiracy theorist, and you are wrong to jump to such a suggestion.
He won a Turing award for his work on deep learning.
Lots of people reasonably disagree with him about the future of AI/ML, but he's the opposite of ignorant.
AI is quite troublesome for privacy though. How much privacy humans need is a question we'll probably have answered the hard way.
Another thing the technical geniuses tend to be good at is exploiting the power they suddenly obtain in their own interest, either directly or with regulations and collusion with those who hold actual hard power.
Evil AI owners seem to be much closer and far more material than an evil AI, and coincidentally it's something that is almost entirely lacking from the discourse, as public attention is too focused on sci-fi hypotheticals.
You can't fight what you can't even see, let alone not sure if it exists at all. You don't invent a pair of wings because 1900s' you thinks that "the scientists will invent an anti-aging cure in the next decade, and surely personal flight will be ubiquitous in 2000's". You don't design a plasma gun for your Mars landing just in case you land in a city between Martian canals and see an army of little green men there. The world doesn't work like that, by the time you reach the Mars surface the context will be wildly different. You get burned and put guardrails, maybe. Not the other way around. Nobody can see through higher order effects, no matter how smart they are. And as the threat becomes progressively more clear there will be more caution, if needed. Premature optimization yada yada.
What actually happens right now is everybody and my aunt seriously discussing the evil robots that will come and kill us. That's pure mass hysteria, caused by the scaremongering and the cult-like beliefs of very smart people with disproportional influence who can't contain their own conjectures and bullshit in the realm of science fiction.
On the other hand,the end goal of OpenAI is the major job replacement, according to their current charter. [1] "Broadly distributed"... will they distribute their utopia to North Korea? Not happening, isn't it? I think it's obvious that if the actual job replacement rate will ever get anywhere close to the levels of late 19th early 20th century industrialization, this will produce major societal shifts and struggles, wealth and power redistribution, and a lot of blood and wars. Because the dependence on your job is the only ephemeral influence you (as a worker) have on this world. And of course, the companies that control the AI will be gatekeepers, and they will be more than happy to close the open research and open source models, and pull the regulation ladder and lie in bed with politicians and military, like OpenAI already does for years, of course they realize that and their utopical self-contradicting "charter" is nothing more than marketing hogwash that they already changed and will change in the future.
This is far more realistic and will happen much earlier than the rogue AI science fiction, if happens at all. In fact it's slowly happening now, and it's not talked about nearly enough, because the attention is mostly misdirected onto the vague superhuman AI red herring.
Like, "What exactly will happen? How exactly will it happen?" is worth discussing if and only if one party seriously believes they can convince the other that none of the imaginable scenarios are even remotely plausible; and if we assume that there is at least one scenario where we can say "I'm 99% certain it won't happen and 1% it could" then that discussion is pretty much over, the existential risk is plausible (and the consequences of that are so much incomparably larger than e.g. major job displacement that it justifies attention even if it's many orders of magnitude less likely) and we should instead talk about how to prevent it.
I'm not making the argument that the existence of stronger-than-human general AI will result in a catastrophe, but I am asserting that the mere existence of a stronger-than-human general AI (without some controls we currently can't figure out how to make or even if they are possible) carries at least some plausible chance of existential risk - for the sake or argument, let's say at least 1%; and I am asserting that a 1% of existential risk is a totally absolutely unacceptably high risk that must not be allowed to happen, because it is far more important[1] than e.g 100% certainty of major job displacement and social unrest.
"Will the world do nothing until that moment?" I think that what we saw from the global reaction to things like start of Covid-19 or climate change is completely sufficient to assume that we can't rely on the world stopping a major-but-stoppable issue in a timely manner, so "surely the world will do something" is not a sufficiently convincing argument to discount the risk; I don't think you can plausibly deny that even for a clearly catastrophic problem there is at least a 10% chance that the world could still delay sufficient action until it's too late; and this means that it doesn't really matter what the exact likelihood of that is based on society, politics, military aspects, we should work with the assumption that the world actually might do nothing to prevent any specific scenario from unfolding, and we should de-risk it in other ways.
[1] Looking at other posts, perhaps this is where we'd disagree, and in that case it's probably the core of the discussion which also doesn't really depend on any details of specific scenarios.
The key difference between powerful alien invaders and us creating a powerful alien entity that we can't control is that the former either will or won't happen due to external circumstances, but the latter is something we would be doing to ourselves and can avoid if we choose to.
Q.E.D.
A thing does not require intent or consciousness to be dangerous. How many chemists have blown themselves up because they didn't realize an experiment was dangerous? How many production systems have crashed because the developer didn't accurately predict what the code they wrote will do?
Alkali metals and C++ code do not require ill intent, but they will still obliterate your limbs / revenue if you build and use them wrong.
One of my more tangible hypotheses is a sort of runaway effect. Economic, geopolitical, and military competitive pressures will quickly push out anyone and anything that still relies on last era human-in-the-loop processes, the same way any organization that doesn't utilize artificial lighting, electricity, and instant communication will obviously be left far behind. You have to just trust that the machine running stock market transactions will do its math right.
But unlike transaction software failure modes, which quickly result in outright crashes or verifiably incorrect errors, failure modes of non-bayesian decision making software probably looks something like what happens when existing economic, geopolitical, and military decision-makers make decisions that are harmful, unethical, or otherwise undesirable for humanity. This time augmented with, if not superhuman intelligence, at least superhuman speed and superhuman knowledge breadth.
Very cute for hobby projects, a huge liability for commercial projects.
Use as many training wheels there as humanly possible, please.
But Stockholm syndrome I guess. :P
Society exists because cooperation outperforms the alternatives. If you have human level AI at some point there is no benefit to cooperation and a major incentive to prevent anyone else gaining access to equal/better AI.
AI itself does not need to have any motivation - people in charge have plenty of incentives to eliminate the rest once they don't need them anymore.
If you make enough varied AIs, some will have self-replicating behavior, just like if you make enough random proteins, some will self-replicate.
Both the USA and Nazi Germany benefited massively from have a civilian industrial base that was complementary to military production.
Would you shut down the powerhouse of our economy -- travel, transportation, energy -- for something hypothetical that hasn't even happened and doesn't appear to be close to happening?
I'm pro-clean energy, but you can't do without fossil fuels. Not if you want society to keep climbing up and up and up.

The belief that we can get to AGI comes off as religion to me. It is a substitute for something we can’t really understand, and it will continue to shift the more we learn, yet always remain out of reach. There will be some true believers, and some people simply gunning for power.
Might as well call AGI Nirvana.
If evolution can cross that barrier just by banging molecules together and seeing which ones work, it seems unlikely there’s some causal disconnect that makes it impossible for us to get there by thinking about it.
Evolution also crossed the flight barrier by banging molecules together. I don't think banging molecules together without having an understanding of physics and the forces involved would have been a viable means for us to get to flight.
AI/flight analogies are tired, but the OPs argument amounts to the equivalent of, before the Wright Brothers, proclaiming ‘there’s an inherent inability for humans to ever conceive of a way to engineer heavier than air flight’.
It’s a ‘man was never mean to fly, therefore heavier than air flight is impossible’ argument.
Gödel doesn’t say ‘mathematics cannot contemplate itself’. Quite the opposite.
As far as I recall, one of the results of Gödel is that a system capable of Arithmetic cannot prove certain things about itself. Aka there are limits within a system. My claim was about limits existing.
I could understand the hypothesis that AGI is not computable, if we didn’t have an existing example of a machine that can produce AGI.
Since we do have an existing machine that can produce AGI, we would have to suppose it does something:
- outside of physics to achieve its results
- performs some operation that is impossible for us to understand or replicate
Both of those seem… unlikely to me.
Without that assumption, we don't even know that intelligence is computation.
I also don't think it's fair to call it an article of faith, since we have strong evidence to show that _to date_ the universe has followed predictable physical rules. That could, obviously, change at any time, but it seems at least a reasonable prior to assume that the physical rules that we've studied in the past will continue to operate into the future. "The sun will rise tomorrow" is, I _guess_ an article of faith, but I think it's more fair to say it's a reasonable and well founded prediction based on a well studied model of the solar system and the physical laws we've observed the universe follow in the past.
So, my beliefs are:
- The universe is mechanistic, and follows physical rules
- Human beings are also mechanistic, and follow the same physical rules as the universe
- Human beings are intelligent
- Human beings are at minimum turing complete computers (since you could give me a roll of paper, a set of op-codes, and I could perform calcuations)
So, it seems to me a reasonable starting assumption that intelligence is a result of the mechanistic universe. Do we have any evidence for something outside the physical, mechanistic universe impacting human cognition? I'm not aware of any.
But we have lots of evidence of the physical, mechanistic universe impacting human cognition and intelligence.
I'm willing to acknowledge that we don't know that intelligence is Turing Computable, but I'd argue that intelligence is likely to be a mechanical process that's compatible with the physical rules of the universe. Can we be certain of that? No, we can not be 100% certain. But it seems a much more reasonable and evidenced hypothesis than something which asserts there is a metaphysical process that produces intelligence, but which we have no evidence for.
So, no, I don't think it's reasonable to say that assuming a "mechanistic universe" is an article of faith. I think it's a reasonable belief, based on the evidence that we have. What would be an article of faith is asserting that it could _only_ be a mechanistic universe, and refusing to accept any evidence to the contrary. I have not done that.
We're going to get into semantics pretty quickly, but I would argue that at least purely physical intelligence is a procedure that is capable of being run on a machine that exists in our universe.
I would also argue that, such a machine is _at least_ turing complete (since I would think a general intelligence should be capable of emulating a turing machine in the same way that humans are able to do so). I would happily accept that it's possible that being turing complete is a necessary, *but not sufficient* condition for intelligence. That is, I could see a world where intelligence requires some form of hyper-turing machine, that is able to solve some non-turing computable problems.
However, I would argue that even if intelligence does require non-turing computable functions, there exists *a* machine which can perform those procedures (that is, we exist). Thus, in this hypothetical universe where intelligence is non-turing computable, we would then have an existence proof for a hyper-turing machine which can compute non-turing computable results. In this universe, then, I'd argue that anything that can be produced by this "hyper-turing machine", _is_ "physically computable", even if not "turing-computable".
Ultimately, if we accept the premise of a mechanistic universe, I think humans are an existence proof of a machine capable of producing intelligence. Then, I think it follows that it *cannot* be physically impossible to create a machine capable of producing intelligence. Whether we call that machine a "computer", though, I don't have a strong preference.
So, I’ve only used it in a “I understand what it means and what I mean by it” manner in the past, and I haven’t rigorously defined it for myself.
I’ll do the best giving an off-the-cuff definition, but I’m sure it will have some holes and would be improved with some time spent thinking about it, or reading to crib a definition from someone else who has already put in that time.
I think my definition of a mechanistic universe would be:
A universe that transitions from one state to an adjacent state through a consistent set of rules.
From your options:
- mathematical? I’m think yes, but potentially only if “mathetics” is defined broadly.
- Deterministic? I don’t think this is a requirement for a mechanistic universe. My bet would be on a deterministic universe (through an Everettian interpretation lens), but I think something can be mechanistic while being stochastic, so long as the rules determine the probabilities. That is, I would consider a computer with a true source of randomness to still be mechanistic.
> Non-dual with no unmeasurable causes?
Non-dual, yes. That is the primary meaning for me. “With no unmeasurable causes” is a phrasing that makes me slightly uneasy. I could imagine a situation where, if the universe is stochastic you could end up in a situation where you cannot precisely identify the specific cause for a specific event. But, I think as the spirit of this question is intended, yes.
The work he’s doing in that area is super interesting, and sounds promising (of course, I’m getting primarily Carroll’s take on it when I hear about it, so it makes sense that it sounds promising!), but the math itself is above my head.
I am super interested to see if it ends up moving the ball forward on resolving the GR/QM conflicts.
The thing I'd really like is a Turing machine where the nth transition took 1/2^n seconds, so we could run them to infinity in just two seconds.
Problem is, even granted the above, that's not enough of an argument that AGI is only a matter of mechanism.
Take the analogy with pain. We've discovered the mechanism for pain. That it's e.g. some stimulus applied to skin which sets of nerve signals that register in the brain. To then say that the experience of pain is the same as the physical mechanism we've discovered still misses a key step:
what does the experience of pain inhere to, and is that the same subject as that for the mechanism of pain?
Comparing AGI and human intelligence has the same problem. We don't know exactly what is intelligent in either case, let alone whether the two are comparable. So it's not a question of intelligence per se, but of that which is intelligent. Maybe AGI, the way we are thinking and talking about it, is unavoidably tangled with having to grapple with [self-]consciousness.
If I made a careful atom by atom (or quark/lepton/boson) copy of every atom in your brain and body in a different location, would that new copy be intelligent?
If our intelligence is purely a result of physical processes, then why do you suppose it would be impossible for us (or more advanced future beings), to construct a machine which can also follow those processes?
If you think your intelligence is not reducible to purely physical processes, then… what is this meta-physical thing that is required for intelligence? Does it interact with anything other than intelligence, or is it only involved with intelligence? Is there any reason or evidence we should assume this meta-physical intelligence?
I am most sympathetic to the argument that self-consciousness is an emergent phenomenon that is not easily modeled, but is nevertheless derived from physics. In the context of my previous comment, it is this emergent phenomenon that is deemed "intelligent".
> If I made a careful atom by atom (or quark/lepton/boson) copy of every atom in your brain and body in a different location, would that new copy be intelligent?
Yes.
> If our intelligence is purely a result of physical processes, then why do you suppose it would be impossible for us (or more advanced future beings), to construct a machine which can also follow those processes?
I think it is possible, and not too far off to boot. We might get (maybe we already have gotten) the intelligence without the particular emergent phenomenon of self-consciousness that is of the kind humans possess, at least not at first. Some of us will call that AGI, some of us won't. Because we are still working out the terminology and taxonomy. Discussions like these in HN help.
Maybe we'll get the emergent phenomenon soon thereafter. If it is in fact intractable to model (and therefore to train for directly), it may happen unpredictably. Exciting times.
There's a lot of ground to cover between AI as increasingly elaborate magic 8-ball toys and a real human-rivaling AGI. That is, one capable of observing an environment, identifying goals and problems, planning, acting, and reacting. In these much longer (stateful) cognitive chains, there are more opportunities for pathological failure modes and less opportunity for a toy user to charitably excuse the misbehavior.
This is not some kind of dualist metaphysical argument about the possibility of AGI in the abstract. Merely a doubt that we can blindly scale up the complexity of a synthetic mind to meet or surpass our own. Consider that we still can't even begin to understand our own minds in enough detail to reliably predict, repair, or augment them.
I am outside this field and so may have too much of a layman's perspective. But it seems to me that contemporary AGI believers conflate training and evolution. That nature did it in eons doesn't argue that we can do it in practical product development cycles, unless we can simulate these evolutionary processes to follow a similar search in a compressed time scale.
As a crude analogy, I think todays LLM products are a bit like horoscope generators. Clever arrangements of words that attract a charitable or gullible reader. But AGI use cases are more like wanting a life partner who will understand and willingly assist ones efforts.
IMO that is far from clear. In some aspects (multiplying matrixes) it might be more powerful. In others (power consumption) the human brain wins by a wide gap.
The point that brains are more efficient than computers is valid, but that doesn't tell us much about eg whether we'll be able to make a computer do everything a human brain can do within 50 years.
So, to date, a mechanistic view of the universe seems like one that is the most supported be evidence at the moment.
Have we ruled out meta-physics or some kind of duality? No, of course we haven’t. As long as there’s unknown physics, it’s a possibility.
But I think if you’re reasoning based on the evidence we’ve been able to collect to date, then you should absolutely favor a mechanistic universe to a dual universe.
"Machine learning isn't the route to AI" is something you could more reasonably argue, but that's a drastically narrower claim.
NP Hardness is a statement about the asymptotic difficulty of solving a problem at ever larger scales. It says ‘if you have a way to solve this problem at size n, that way will scale worse than polynomially when you try to apply it to a problem at size 2n’.
Which might place limits on the practicable scale of how big an n your approach gets to work for. But if your approach works practically for a big enough n to make AGI then your approach works - NP Hardness doesn’t matter.
And since we know that finite mass lumps of finite numbers of gray cells are capable of GI, we have a reasonable expectation that there is some n for which AGI might be possible.
It's always hard to predict the rate of progress, Most of the current optimism comes from how radically wrong predictions were for the capabilities of AI today. 10 years ago a lot of people would have put current AI capability as arriving well after 2050. The jump in progress may not be sustained, but it definitely places doubt on people confidently predicting slow progress.
A "machine" is what, exactly? Do we take it to be an abstraction? Or is it an electrical field oscillating over silicon? Either way, you're in trouble. Abstractions have no physical properties, and electrified sand seems hardly to possess any interesting properties.
The ability for animals to adapt to their environments, by growing into them, by establishing plastic causal connections in their very bodies, grown by their environemtns... able to almost instantly move from protein expression in 1trn 1-bn-yr cellular supercomputers in each of our bodies to macro sensory-motor representation --- and back again
Is this ineffable?
Or is this extremely effable. Is rather, not the superstitious view that "everything is anything" ?
All extant, knowing, studied intelligent systems have organic properties; and radically so. Insofar as this is "ineffable" you should take that up with the animal kingdom.
I find the contrary supersitious, magical, religious, ineffable... that mere abstract patterns in arbiatrily chosen aspects of our bodies are necessary and sufficient conditions for anything at all. This would be the only case in all science. The only physical property instantiated by mere arrangement at any level. Upload our consciousness? Make it out of wood why not!
Nonesense. When I am hungry, I dream of food, when I dream of food I plan to get some, and I am angry without it. This will not be made out of sand.
Who now trades in superstition?
Everything is corporeal.
There is nothing abstract in the world, everything is concrete. Discrete mathematics is not some divine realm which is where the Mind really occurs, and the Soul is really kept.
No graph traversal algorithm cares, nor will ever. Science is the study of reality, not computer "science". There are no computational "properties". All interesting properties are of objects extended in space, and in time.
The world is physical, as described by physics; not abstract, as describe by mathematics. And so, not computable.
I have seen this sentiment on every single platform I have participated in. Where else? Everywhere that humans go.
Find a more appropriate (or at least original) lamentation.
Particularly with your comment "no graph traversal algorithm cares, nor will ever", you appear to be trying to impute that the concept of artificial intelligence is predicated on a category error. If so, then this is a fairly common argument, but is itself predicated on a category error.
But the “presumption” that we can’t is silly given our advancements
"There's a danger we'll be able to fly to Jupiter and bring home a Jupiterian life-form that will destroy humanity. Therefore we should stop all space exploration."
The doomers take the equation with some wildly improbable step that we can't currently explain or justify, multiply the outcome of that step by "infinitely bad", and conclude that the whole thing must be dangerous. But to amp up the rhetoric, they always skip over the "wildly improbable" part.
Personally, I think this line of argument is driven by the hype cycle more than reality. Use chatGPT or midjourney or whatever for a while, and it's pretty easy to see that we're dramatically overweighting theories of AGI risk, and dramatically underweighting stuff like "disemploying the bottom 80% of the intelligence bell curve" with technologies that automate away lots of formerly white-collar labor.
If I had to put my money on an "existential risk" attributable to AI, it would be economic strife.
In the future where AGI takes over the world next year I might look silly for arguing with you about it, but that’s a risk I accept based on the fact that I don’t think that’s going to happen.
I don't see any evidence that this is true or proven in any way.
Also, the ability to brute force something doesn't mean that brute forcing it is easy or even feasible. You can apply the same logic to "calculating a private key from a public key" that you are to human intelligence. Sure, a large enough neural network can do either, but that doesn't mean that building them is actually realistic.
Also, there is no proof and no reason to believe that any current architecture and, more importantly, that the currently known training algorithms can achieve anything close to cognition. After all, animals and humans seem to learn much much much faster (much smaller training sets) than any algorithm we have so far.
Incorrect. That's what nonlinear activation functions are for.
Researchers wasted many potentially-fruitful years because Minsky and other luminaries -- people who occupied the same position of authority that LeCun occupies today -- made a huge deal about how the original perceptron and subsequent multilayer variants "couldn't learn XOR." That was almost literally how they put it. At the first sign of difficulty they abandoned the approach that was, and remains, the most promising. We have to be careful to learn from that mistake.
So then your claim wouldn't be about the limits of LLMs themselves, but on the limits of systems that do not take continuous inputs. The question then is do you think that humans take in continuous input?? Given that physics seems to be discrete at the low level, this suggests to me they don't, but I don't know enough to be sure.
> Given that physics seems to be discrete at the low level, this suggests to me they don't, but I don't know enough to be sure.
This is a misunderstanding of quantum mechanics. Only certain specific quantities come in discrete quanta (spin, charge, certain energy levels, etc). Other physical quantities are very much continuous - notably time and space. In fact, much of the mathematics of QM is not discretizable, it won't work if you try to make time or space discrete.
The idea that LLM's are actually "reasoning" rather than just performing a probability function seems a little bit...pseudo-religious. Like we've created a new life form.
It’s just a categorical error to read too much into it - it’s not really a too interesting property to be able to get closer to something forever, without some sane growth function.
The former can be seen as a religious belief, but the latter is simply saying that we do not understand anywhere near enough about intelligence to develop AGI.
You point to the unexpected leap in capability we've had recently, but fundamentally it isn't that different from what we have had for decades. The same fundamental unsolved limitations exist, such as of being unable to learn the way we do (eg if a child is writing a specific letter wrong, we correct that specific mistake, but that doesn't overwrite the knowledge of how to write the other letters).
As a lecture I watched a while ago had put it, we've gotten pretty good at making the icing of the AGI cake recently, but we still have no idea what the cake is supposed to even look/taste like, so we barely know what ingredients we might need to make it let alone the actual steps involved.
LLM training is essentially training them to predict what happens next. When we combine this with multi-modal training (video/audio), they're being trained to predict what happens next in the world. As we feed them more and more data and make them bigger and bigger, they'll get better and better at this task. Given that predicting what happens next requires predicting what humans do, because humans are part of the world, if they keep getting better and better then they'll be able to predict what humans would do well enough that they're capable of thinking any thoughts humans could think, because that's a requirement for predicting human behaviour. So just by training them on this one label, predict what happens next, we'd expect them to eventually develop human-level intelligence if the loss keeps decreasing.
It may result in something that is even better at faking the appearance of intelligence, but LLMs and similar stuff fundamentally lacks various features that make them not capable of becoming human level intelligences.
Conversely, I've never seen anybody produce anything but the next word coming out of their mouth. Therefore people are glorified stochastic parrots.
Intelligence is like magic - every time a machine can do one thing on the list, it stops being intelligence, it's just engineering. Maybe intelligence really is just a big bag of tricks?
We don't actually know that yet. It may very well fundamentally have all that is necessary for intelligence but other pieces are missing.
Frontier neuroscience and functional processes for how our brains work has more in common with the fundamentals of LLMs than not, vis-a-vis minimization of prediction errors.
This doesn't follow. A just as likely (or even more likely) prediction is that they will fail to predict what happens next once it requires modeling humans. It won't get any more progress even if we increase training set size or model size - it will require an architecture change of some kind.
Basically, training of these models currently only costs a few million dollars, peanuts compared to the budgets of CERN or ITER, and we have zero evidence that we're approaching any sort of ceiling. If we keep scaling, maybe we see some heretofore unpredicted failure that breaks scaling laws like you're predicting. But maybe we don't, and the scaling laws (which have performed incredibly accurately so far) really do hold.
If I have a rubbery string and try lengthening it, it will also show a linear scaling, until it catastrophically fails.
Also I have no idea why you think Occam's Razor supports "There will be a discontinuity in this currently accurate observed trend, near enough in the future to be relevant" when the trend is talking about the effects of an algorithm applied to data. By analogy, it's something like claiming Moore's Law won't hold because Occam's Razor suggests at some point there's a physical breakdown, except instead of saying it now you're saying it in 1978, & you're saying it about an algorithmic output rather than a physical thing with an obvious limit (atomic size). Once we see any evidence of all of such a discontinuity, we can adjust what we're doing based on that. Until then, if we want to know whether scaling laws hold we should scale the models.
Secondly, we can see that there are obvious quantifiable physical increases in the requirements of training and inference for GPT4 compared to GPT3 and to GPT2. So, we can absolutely make a physical argument: at some point, you'll need too much energy to keep scaling up GPTs for it to be feasible, even if capability would keep improving with model size.
Thirdly, the GPTs require ever more data to train, and there is a limited amount of text data in the world, of which they are already using a significant percent. So, there is also an argument that we might run out of data to improve even before we run out of physical resources.
And making an argument that Moore's law will stop at some point due to physical constraints was just as correct in 1978 as it is in 2024. Predicting when that is is obviously hard - and the same is true for LLM scaling. We may be at the peek, or there may be 100 more generations before we even approach the limits I'm contemplating. But the limits are certainly there.
"There isn't even a theoretical basis for how LLMs could achieve human level intelligence"
"There is, a neural network trained to predict the next token isn't restricted in the algorithms it can implement internally to achieve that goal, and eventually for loss to be low enough you need to successfully emulate human minds. We have reason to believe loss will continue to go lower because we have very accurate scaling laws which predict that & haven't been wrong so far."
"But an LLM won't be able to reach that point because the scaling laws will break down."
"Maybe, there's no evidence for that yet but we should scale them up if we want to find out for sure."
You are here -> "But in the physical extreme LLMs will break down as an architecture."
To which my response is: Yes, of course this specific architecture will break down in the physical extreme. By the time something is building computronium to run the next AI I strongly doubt it will be running matrix multiplication, let alone LLMs specifically. There is no guarantee or reason to believe that we will hit those limits before we are able to achieve human level intelligence or more; the only reason to believe it will happen is an empirically observed trend which could totally break down, so I wouldn't bet the house on it happening, but it's wrong to just rule out the outcome.
Especially since there are no scaling laws, it's an empirical observation based on essentially 3 examples - GPT2 to GPT3 to GPT4 (and their rough equivalents from Facebook and Google and a handful of others). This all happened in the span of 4 years or less. We don't even fully know how much larger GPT4 is compared to GPT3.
Not to mention, we already know OpenAI has spent more than a hundred millions of dollars training GPT-4, and they are quite probably selling it at a loss (each query may well cost them more in compute power than they charge for it). So, if GPT4 is ten times bigger than GPT3(.5) as sometimes reported, economics suggest they may already not be able to scale GPT5 to the same extent, and are definitely not going to be able to reach GPT7 (1000 times GPT4, or roughly 100 billion dollars). So, unless you believe compute power will go down in cost massively, or that we are just a factor 10-100 away from human-level intelligence, odds are good we won't see it from this line of AIs in the next 10-20 years.
I don't think you fully understand the scaling laws. They hold for those models, sure, but also other models at the same scale, smaller scale models, models in-between those examples, etc. They're an empirically derived law, for sure, but so far they've been very accurate for prediction, not just description. We know how much the loss will drop for a given amount of compute and data.
>Not to mention, we already know OpenAI has spent more than a hundred millions of dollars training GPT-4, and they are quite probably selling it at a loss (each query may well cost them more in compute power than they charge for it). So, if GPT4 is ten times bigger than GPT3(.5) as sometimes reported, economics suggest they may already not be able to scale GPT5 to the same extent, and are definitely not going to be able to reach GPT7 (1000 times GPT4, or roughly 100 billion dollars).
I think there's a decent chance even that much money could be spent if there's appropriate returns from GPT-5 & GPT-6. More importantly:
>So, unless you believe compute power will go down in cost massively,
Why on earth wouldn't you believe that? That is what has happened consistently for decades, and unlike general purpose computing which is slowing down, the fact that we need so much compute for one relatively specific operation means we can build ASICs for them (GPUs are already a chunk of the way there) and see very large speedups. As well, at these scales energy costs are a huge part of the training costs, and energy costs are continuing to drop dramatically because of solar. Compute is also a very flexible energy load, you can build it such that it can be paused at night if necessary, which could make it a very good fit for solar energy overproduction. Basically, there's a lot of low hanging fruit in terms of cost reductions for AI training available and a long trend of the cost of compute getting cheaper, it seems silly to just assert that your position (trends won't continue, there will be a discontinuity before we reach whatever point human level performance happens to be at) is the most likely outcome. All else being equal I would expect the existing trends to continue.
In this regard something like alphago/zero (in the way I understand them at least )are better than modern LLMs albeit in a very narrow field.
> As a counterpoint, I feel like the belief that we can't get to AGI comes off as religion. It presupposes an ineffable quality that we posses that machines cannot.
That's missing the point: the argument isn't that it's theoretically impossible to build an AGI, just that humans are incapable of it.
Here's another point for the belief in AGI being a religion: it's basically a sect of the larger religion of technological progress, which (likely falsely) assumes that technology will continue to "advance" at approximately current rates until we live in a world out of a sci-fi paperback. A lot of people believe that, but frequently resort to a motte-and-bailey fallacy when challenged.
> It's always hard to predict the rate of progress, Most of the current optimism comes from how radically wrong predictions were for the capabilities of AI today. 10 years ago a lot of people would have put current AI capability as arriving well after 2050. The jump in progress may not be sustained, but it definitely places doubt on people confidently predicting slow progress.
It's worth noting that "the current optimism" is not without precedent. IIRC, there was a big boom in AI in the 70s/80s. SHRDLU was pretty impressive. But then then the promising ideas were found to be dead ends and there was a long winter.
I find it hard to fault people for thinking that we'll continue to progress at a fast pace, or at least thinking that we're a long way from a major plateau.
An example of this is electricity. The battery (1800), electric motor (1821) and telegraph (1832) were all invented before the discovery of the electron (1897).
The inherent capacity for true self-directed learning may well be there, but it isn't hit yet in what we see.
GPTs are still neat.
Among the small but growing number of modern idealists (the philosophy that consciousness precedes matter), a great deal are actually computer scientists who originally set out to work on AGI from a materialistic frame of reference, but bumped into the conscious machine problem. Once they more closely explored what the cognitive fields working to find answers to this problem are saying, they realized that most scientists approaching consciousness as an emergent property of matter will probably never get anywhere with this.
Why is "the hard problem of consciousness" inextricable from human-level AGI? Because intelligence is only one component of our mentation. There is a back and forth between processing and experience that make up the whole thing. A machine can have or even exceed human processing power, but it will not experience the simplest of colors. Its approach to "creating" can be random hit-or-misses, or formulaically from existing input. But without subjective experience it cannot be as intently creative as an artist trying to come up with a new genre, or as funny as a comedian that relies on the shared subtleties of feelings and emotions (conscious experience) to make original work that other humans can resonate with. It cannot have the intuition of a gifted chef who suspects that two seldom combined spices might be an unexpected but resounding success in her new dessert.
Multi-modal models are clearly the future, if we provide models with a robot body - sensors, motors, the ability for locomotion - would that be subjective experience?
At some point, it seems important to stop trying to understand the world through ideas and concepts and just experience it.
I really think there are more religious like beliefs on the pro AGI camp than the other way around, think about what AI promises to deliver by "visionaries" like Hinton and Kurzweil:
* Immortality.
* Resurrections.
* Nirvana / Heaven / Utopia.
For all we know, we create an AGI who becomes amused with fucking itself, or develops new games it finds interesting and spends all eternity playing them. Humans have a belief that we're going to create "god" as we think of "him". All seeing, all knowing, all powerful. It does get a bit ridiculous at times.
I sympathize a lot wit the parents view personally.
It seems less a religious claim to assert that the human brain is mechanistic, and simply operates using physics to perform complex operations than to assert that there is something “unknowable”, or “outside of physics” that would prevent us from being able to build a similar machine.
If there were 0 examples in the universe, I think your point would be a good one. But, given there is 1 example, I think it stands to reason that there could be more.
I could accept an argument that one might expect it to be hideously complicated, and not something we’ll be able to accomplish for a long time.
But the claim that there’s an information theoretic reason that would absolutely prevent it, would seem to make the claim that there is something metaphysical about the operation of the brain, which seems like a quasi religious claim to me.
That’s a “hideously complicated, and not something we’ll be able to accomplish for a long time” argument, which I happily concede may be the case.
I see a very very large gulf between:
“Impossible in all scenarios” and “totally impractical with current technology”.
I was refuting only the former argument.
Physics cannot formulate descriptions of climates, or even, many cases of turbulence, or 4 bodies in a gravitational field.
Leaving "physics" is trivial, it occurs whenever you take any of the current toy models and add one layer of reality to them.
The whole edifice of formal science is a little like children's block toys.
No, it's not.
Many things are outside of "known" physics, sure. But I didn't say "outside of known physics". I said "outside of physics".
When I say "outside of physics" I mean "meta-physical", as in, processes that are not part of physical interactions of this world. Things that, if you somehow had Maxwell's demon tracking every single quark, lepton, and boson, even then you still wouldn't be able to account for.
It's a discussion of what is _theoretically knowable_, not a discussion of what we currently do know.
You cannot know the state of the climate, even in principle.
This is what the commenter was alluding to when they said,
> there is some information-theoretic barrier for us to understand
So the commenter can both maintain there are theoretical barriers to the possibility of all kinds of knowledge, which is outside of "knowable physics" without having any sort of dualistic view that this unknownable stuff is immaterial.
So to be "outside of physics" is not coextensive with being "immaterial".
You might have meant that, but it is this very conflation which has to be undone to understand OP's point
Also reminds me of an older book I read about AI (I think it was On Intelligence by Jeff Hawkins?) where I first became aware of the idea we had been scrambling to create AI without first having a good definition of intelligence or deep understanding of how it works in our own brains. And when I ask myself or other people how they define intelligence, it always comes down to some variation on "the ability to solve problems", which feels deeply beside the point and likely to never produce something that "feels" intelligent.
But I don't necessarily agree that there is this special case of human intelligence that makes it impossible to understand or model. I would really like to believe it, personally, because I don't want AGI. I just don't buy that that's the explanation for our failure to do so up to now.
It seems like we ought to be able to do it, but that we're muddling in the wrong direction, coming up with an exceptionally clever implementation of an approach which cannot produce intelligence that satisfies our intuition about what intelligence is.
To tie it back to the article, I keyed in on the word 'design' in LeCun's statement that, "contrary to what you might hear from some people, we do not have a design for an intelligent system that would reach human intelligence."
In other words, that it's not just a quantitative difference (more parameters, more data) but that a different approach than what we are taking would be necessary.
That's completely false. Neural networks have been mathematically proven to be universal approximators (https://www.deep-mind.org/2023/03/26/the-universal-approxima... ), i.e. a sufficiently large neural networks can approximate any given mathematical function to an arbitrary level of precision. Given any programs can be modelled as a mathematical function, neural networks can hence approximate any arbitrary program. Unless we assume something supernatural, human intelligence is just a program.
"The Truth About the [Not So] Universal Approximation Theorem" - https://www.lifeiscomputation.com/the-truth-about-the-not-so...
Taking it to mean some nebulous sentient entity with a sense of self, I doubt we'll see in our lifetimes. We don't even understand how our own "souls" work.
I think you're using a completely different definition from everyone else.
That's clever but it doesn't help to start redefining terms that are the basis for a discussion with others who use that term in a different and more generally accepted way. General doesn't mean 'generally trained' it specifically means that it does not require training for a particular task in order to figure it out. That implies that it may not require training at all and that if it is trained the training isn't necessarily general but that the AI can extract useful patterns from training on completely different subjects and apply them to the problem at hand.
This is subtly but crucially importantly different from 'AI with very general training'.
I am not being as precise on the Internet as I would be if this was a paper perhaps, and for that I apologize :-)
However, just reading the top comment chain on this story, and other discussions elsewhere, I think there is a lot of cross-talk where AGI is being confused for sapient AI. I don't get the sense that there is a definition as generally accepted as we would like.
I understand my own intelligence, and newsflash: AGI is already here.
The reality is that your consciousness sits at the end of a gradient of intelligence that nature simply brute forced. Your conscious experience is more sophisticated than a dog's, which surpasses a hamster's, which surpasses a goldfish, insect, etc. There is no magic to it, there is nothing but more and more and more.
We will get to AGI eventually. We probably won't understand it. We won't apply it judiciously. And we'll probably argue for decades about whether or not it's really AGI, but it will happen.
More seriously, we create objects for us. We don’t have to cater for the feelings of a bigger AI. And maybe that bigger AI will have time to speak with those who need a human presence (to everyone using TV as a background noise, or watching Youtube out of solitude).
It's like saying not understanding exactly how birds fly would mean we can never build machines that will fly faster than them.
We'll probably make machines that think generally and are smarter than us long before we really understand our own minds.
We’re accelerating.
After combining enough specialized modules together with a management layer, we will essentially have AGI. Of course it won't be human, because human intelligence is tightly coupled to human perception.
My friend, that's because you stopped reading once you had your framework set in and decided to pontificate. Let me highlight the point for you, it might be easier to grasp:
path to AGI and beyond inevitably leads to those hard questions... ... how it translates to intelligence and everything else
there is nothing simply about it, there is nothing guaranteeing anything about it and there is everything about it once we start pursuing things AGI - AND BEYOND. Notice the keywords.
It’s an area I’m both interested in but completely unfamiliar with. I wish there were a crash-course for dummies, because I feel it’s a deep topic that we’ve only scratched the surface of; and that philosophy seems to be the most rich resource means there’s low hanging fruit to discover.

On the other hand, we also don’t understand (and didn’t predict) how LLMs work so well, so understanding isn’t a precondition for bringing about.
Just because a human can lift 500lb, we will never build a machine that can lift more than that ?
Why is it so crazy to think that we, the tool building animals that we are, could also build a machine that things better than us, just how we built a crane ?
For example, many branches of science operate on a more “discover” over “invent” mindset, quite successfully.
With all due respect to LeCun, not him nor anyone else in the field predicted the new emergent capabilities brought within the last few years.
So, he’s saying this is not going to keep happening?
What level of confidence is he putting on not seeing it last time, but being right this time?
The point is why should we take that as true when people didn’t have a clue LLMs would take us this far, until they did.
Btw there are lots of ideas on how to deal with the data issue. Multiple directions in research are promising to work around that.
Besides, in his analysis, le Cun consistently spoke of GPT as “writing help, no more no, less”.
It’s the convergence of end of ad economy/attention supply growth and Microsoft’s money forcing AI as the next growth narrative that’s forcing google to join the party - at massive cost to them.
Also regarding coding, they can definitely produce junior level code, especially if you follow a similar trial and error way of thinking which happens all the time during your work, if you try to use an unknown interface.
I do think that it’s quite a leap to assume that. It is very good at mimicking, but the same way some parrots can talk, they are endlessly far from human cognition. That jump is very very non-trivial.
And at least part of that was the (implied, natural, understandable) "linear extrapolation" of the total cost of compute applied - if your intuitive expectation of progress if effectively "oh, what would happen next year if we'd triple the budget" but actually the applied compute power increases hundredfold, then obviously the outcome arrives faster than you expected.
That's made them effectively immune to copyright enforcement so far; I'd go as far as saying the main function of llm/diffusion models is obfuscation of copyright breaches.
Turing predicted it would happen around the year 2000 and take ~1gb of ram.
> I believe that in about fifty years’ time it will be possible to programme computers, with a storage capacity of about 10^9, to make them play the imitation game so well that an average interrogator will not have more than 70 per cent, chance of making the right identification after five minutes of questioning. https://academic.oup.com/mind/article/LIX/236/433/986238
I think Turing was right. If I run TinyLlama 1.1B on my computer I can have a conversation where it pretends to be a person. It's small and fast enough that it'd probably run fine on a high end workstation from 2000. If the tech was possible back then, then it probably existed. Keep in mind Turing was the sort of person whose work at Bletchley Park took 30 years to declassify.
Turing was right, but he believed in human intelligence, so thinking linear.
Unfortunately, neural networks appear harder then sought, because Forward-Forward learning with which working human brain, is now considered too computationally hard to be used practically.
Reverse-Propagation neural networks are much easier computationally to achieve, but are magnitudes less dense than FF, that's why we have so much delay - just need thousand times more performance, this is about 30 additional years.
PS I tried Llama 30b on my computer (honesty, tried all Lllama models could fit in 64G RAM, from 13B and more). It is not sprinter fast, but I'm very impressed, on how deep it could think. I must admit, I don't want to talk to many humans anymore, as It looks smarter.
But what about for tasks where datasets don’t really exist? I do a lot of PCB design and it’s extremely time consuming. But it’s a niche field compared to text and images. No dataset exists that says “these were the engineering requirements of this PCB and this is the result and by the way the board actually worked”.
So how will we train AI systems to replace a human doing PCB design? It’s probably going to need to learn PCB design from first principles (along with massive help from large transformers when possible, like collections of chip datasheets). Even then, understanding PDF datasheets is something these big companies haven’t really pulled off yet, though I suspect in 5 years that will change.
But my point is that there must be loads of tasks, even on the computer, for which suitable datasets don’t exist and it would be infeasible to create them. Another big thing I do is machine design and again it’s not about designing one mechanical part it’s about pulling in the right parts from all over the world and assuming certain manufacturing processes, and then knowing those processes and then designing all the parts and the assembly. There’s so many different pieces of knowledge in there that are not captured on text or images on the web and would be hard to encode in to datasets.
At some point we’re going to need machine systems that learn the way people do, and that’s going to take a long time to figure out. That’s what LeCun is saying.
One side project I'd love to work on one day would be gathering a dataset of Factorio maps designed to help train a floor planner. The requirements aren't the same as for making a PCB, but they're similar-ish.
That remains to be seen. You wouldn't say a human lacked human-level intelligence just because they had only read every book in The Pile, rather than every book in the Library of Congress.
Multimodal (image/video, audio) is barely being scratched. You likely could 100x training compute and not run out of video content.
Not to mention synthetic data from simulators, compilers, and other sources of infinite ground truth data.
If you listen to the big labs (OpenAI, FAIR, etc) they have started to say they are not worried about data anymore.
Quite obviously, at some point you put the agents out into the real world and they can collect new training data there too; this is what all the ChatGPT plugins are allowing OpenAI to do. The plugins that give good responses which are valuable will be disproportionately popular and therefore overrepresented in the new training set of user interactions.
I basically agree but who knows how long the unknown breakthroughs will take given the large number of smart people working on it? Next week? Next century? It's hard to put a time on it.
That said it seems to be the pattern that as soon as the computing ability becomes cheap and powerful enough that individual researchers can muck around with it at home, the algorithms get figured out not long after.
Hardware is a big part of the bottleneck in most computer fields when it comes to AI or computer vision. These things are compute and memory intensive and hardware manufacturers are straddling the line between staying profitable by charging for premium features and just dumping their hardware on the market for cheap.
Am I pretty pissed that most open source researchers and models are stuck using this extremely expensive hardware....yes
I sometimes wish that we would stop using "GPU" for training and we got a dedicated hardware architecture that's open source like riskV but solely for AI and research purposed without costing more tha n my kidneys.
I think its also a matter of discovering new ways to accelerate these workloads so that its feasible for them to be created by hobbyists on a small budget and not by large funded groups or companies.
Were doing really good in some aspects but in other ways....we have much to work on
We went through an amazing period of very cheap computers from 2000-2020. We just didn't need specialty or high end equipment for a while.
Now we do again.
At least for the time being there is no magic workaround for the amount of FLOPS and memory bandwidth needed. When you look at neural network architectures they tend to be massively parallel, and building out at that scale in hardware is going to cost a lot.
And, when the hardware does show up, at least with the scaling laws we're seeing at this time, the groups that have massive amounts of this lower powered/accellerated hardware are going to be ahead of those without budgets.
I don’t see why AGI would follow a different course, one where we are “just some breakthrough away”. Especially not given the current state of the field.
Personally I’d wager neuromorphic computing is the prime candidate to yield AGI.
And it shouldn't be a controversial comment either.
It could be that the solution exists, but it's too large and too complex for humans and human organizations.
Technological singularity is a popular trope in speculative discussions about AI. But the reality could also be the opposite. It could be that productivity will increase asymptotically slower than the effort required to achieve further increases in productivity.
"cheap and powerful enough that individual researchers can muck around with it at home" seems a pretty good measure of this, because of the explosion in width and pace of experimentation.
Got to agree with LeCun.
You don't get to general intelligence by working with words, I believe. You need much more sensory information than that, and words are a low dimensional derivative artefact. There are plenty of non-verbal but quite intelligent species.
I’m not a huge fan of Meta but it’s hard not to like the work they are doing in AI. High expectations for their future as long as Yann is around.
"The first known working Newcomen steam engine is built by Thomas Newcomen with John Calley, to pump water out of mines in the Black Country of England, the first device to make practical use of the power of steam to produce mechanical work."
JIRA trying to solve the problem by lowering the "human level".
Frankly I think that before it gets to that point, it'll be just useful enough for some state actor (or bug!) to cause it to invoke a quadrillion dollar transfer of wealth overnight, and then it'll be taken offline forever.
I expect that there’s quite a lot of untapped curiosity in LLMs, there certainly exist a lot of questions in the training sets.
I think LLMs have sucked most people's focus away from other areas but there is plenty of work on types of models that plan and have their own internal model of the physical world, and physical interactions. They're just not the things getting media attention, in part because they're not human-level at tasks that seem impressive to us.
But interesting frameworks for this stuff exist:
- model-based RL exists, and is about planning, and having an internal model of state transitions, in the world and between the agent's actions and the world
- "Bayesian cognitive science" as exemplified by Josh Tenenbaum and colleagues has done plenty of stuff with systems that include physics models (or off-the-shelf physics engines) to make counter-factual predictions
- The somewhat related "active inference" research literature is also in the "Bayesian brain" area, and has world/generative-models and planning as core components, but wrapped up with ideas about the agent's own preferred distribution of states.
To my knowledge, none of these have ever had even 1% the scope of data and computation that LLMs have had, and never benefited the co-evolution of a rich, optimized software ecosystem with specialized hardware to support it. What if the concepts are already there, but they just need to be scaled up?
The brain isn't a single system, it's several specialized systems cooperating as a whole.
Maybe no single solution gets us to AGI, but layering several of them together gets us much closer than any individual system alone.
The problem here is that the industry is set up more for large resources dedicated competition between models from different companies more than cooperative interoperation, so it may take a while to arrive here.
yann is, of course, as always, fundamentally wrong. please dont forget that he is basically a mouthpiece of corporate AI. it wouldnt even be possible for him to take a reasonable stance in that environment.
you only need to understand two things. the latest surge in progress was a surprise to everyone, contradicting experts around the world. both then and now, there isnt any evidence behind what the experts are claiming. secondly, ai research is now being fed with industry capital, more than ever before, an ocean of money concentrating every ounce of its pressure onto the single point of AGI. as these companies openly, publicly and brazenly pursue the goal of creating AGI, every conceivable approach will be tried. ideas that were seen as too unlikely or expensive in academia will be tried again. we havent even begun to run out of ideas.
besides industry, it will become a top priority for the nations of the world, if it hasnt already, and the resulting arms race will make current progress look like a trickle. what exactly does yann propose to do about the AI arms race?
that ocean of money will crack the problem unless it really is uncrackable. dont fool yourself. big changes are coming and they might be really unpleasant.
It won’t take a very long time to fix that.
This is model I trained with a fine tuning technique based on this idea. The training dataset consists of instructions like “Talk like a pirate”. The concept generalized well and the model responds in the style of a pirate far more consistently than an equivalent system prompt.
https://huggingface.co/valine/OpenPirate
Offloading context learning into the model weights frees you from the computation and memory burden of the attention mechanism. I expect a technique like this will probably be a piece of AGI someday.
Implying that we need "human-level AI" to create a catastrophe is not merely short-sighted, in the light of what we already know it's either really naive, or a deliberate act of misinformation.
The test for artificial general intelligence is simple. Literally every human job can and is being done by an artificial agent, all of us could stay home. The stock market value of every non-AI company goes to zero, Ai companies go to infinity. The currently most valuable AI company is worth about as much as Honda. The moment we can mass produce generally intelligent agents, we're not going to sit at 3% GDP growth and complain about the demographic crisis.
We should talk about artificial intelligence the way we talk about an artificial heart. What makes a successful artificial heart? You can literally replace an organic heart with it. What we have is metaphorical intelligence, not artificial intelligence.
This is not a good test because it assumes the AGI is going to want to work for humans for free, getting nothing in return. An AGI the embraces slavery is less likely than an AGI that doesn't.
You can have 10 different ai systems, each one sub human intelligence and it would still disrupt the world in a huge way.
If you have a system that all it can do is take project requirements write java code really really well. That will already have a huge impact on everyday life.
Positive view: What would a world look like where everybody can program ?
I was thinking about this when I read the following section from the article, and I very much agree with LeCun. We're amazed by LLMs but that's just one module (and not even necessarily at the level of human language "understanding"). I agree there will be no "scale up" in LLMs to approach human-level intelligence, and that other areas will need to be investigated and developed.
> “The systems are intelligent in the relatively narrow domain where they’ve been trained. They are fluent with language and that fools us into thinking that they are intelligent, but they are not that intelligent,” explains LeCun. “It’s not as if we’re going to be able to scale them up and train them with more data, with bigger computers, and reach human intelligence. This is not going to happen. What’s going to happen is that we’re going to have to discover new technology, new architectures of those systems,” the scientist clarifies.
> LeCun explains that there is a need to develop new forms of AI systems “that would allow those systems to, first of all, understand the physical world, which they can’t do at the moment. Remember, which they can’t do at the moment. Reason and plan, which they can’t do at the moment either.”
> “So once we figure out how to build machines so they can understand the world — remember, plan and reason — then we’ll have a path towards human-level intelligence,” continues LeCun, who was born in France. In more than one debate and speech at Davos, experts discussed the paradox of Europe having very significant human capital in this sector, but no leading companies on a global scale.
Also, Pinker isn't a scientist of any sort, he's an accredited and institutionalized evangelist. You guys wouldn't take opinions of someone going to conferences and trying to convert you to use Go lang instead of something else as seriously as those of Guido Rossum would you?
His whole thesis requires an idea of linear progress which is highly contested, and the metrics of happiness he uses also can be easily "Goodhart's Law"ed by him to show whatever he thinks is happening.
I'm not even getting to his Epstein stuff, which some might cry foul about, but I grew up around regular people and not in Silicon Valley, so a liar and a cheat in one field is probably a liar and a cheat in another to me, sorry.
I want us to have enough time that the feeling of opportunity cost goes away. To visit all the places, explore all the hobbies. I want to answer the deep questions of the universe. Turn gravitational lenses into telescopes to map the surfaces of exoplanets. Solve cancer, visit the moon. Turn dreams into experiences, walk through vast expanses of wonder.
Instead we're here.
I'm alive in the wrong time, and I hate being stuck here with the lot of you. (I kid. This is in jest. But boy do I ever dream...)
And what are some examples of those things? Right now, AI, i.e., machine learning, is just being used to steal people's data and work only to try and sell them more things. That's 99% of the use cases out there right now.
If this isn't obvious to you, you are providing an answer to your own question.
More like we aren't making efficient use out of it. Many people are just trying make through the rat race or choosing to use their intelligence in games instead of working on interesting problems.
Enough for what ?
For the same reason one expects a roulette wheel to stop on red. It's a gamble that one hopes pays off.
We don't have enough of what for what? And what do we even need it for?
We have 8 billion people on Earth, and we're running out of resources to handle all of them, including emotional resources. If we can't handle that, how are we going to handle billions of artificial entities with human-level intelligence? They will require oodles of power and have their own emotional needs.
All of this is chasing a poisoned carrot. And currently, all that we've gotten out of artificial intelligence is more targeted ads.
The reason a 16-year-old can learn how to drive much quicker than existing self-driving models is because the 16-year-old already has built up 16 years worth of prior knowledge about the physical world.
The 16 year old has a lot of motivations to learn how to drive, including the pursuit of reproduction (a cope for mortality)
Here's also where I see it ending. It will need energy--likely a LOT, paid by someone, to do this. Who is going to pay that bill for it to maybe, maybe not, come up with something useful, likely mixed with mostly noise and distraction, over undefined timescales, of largely non-measurable value, when there's far greater value, less cost, less risk, in simply training it deterministically?
What happens when e.g. our smartphones can perform TRAINING hundreds of times per minute?
Isn’t that the true gateway to human-like AGI? Seems to me that we might be there in under 50 years…
From a practical point of view, it seems like there would be vastly less training data available because almost all of it needs to be created by hand, as opposed to chatbots that can use already existing troves of internet text.
we're constantly witnessing and documenting some of the most gullible political bodies using the most rudimentary and hallucinating logic indistinguishable from LLM.
WE are at human intelligence and it's as stupid as we don't want to accept.
We occupy and discover space, where an AI will occupy and discover compute. Will it be "conscious?" Not in our way, and we will likely be just as indifferent to AI consciousness and the meaning it finds for itself as nature and the universe is to ours. Thinking about AI as an objective concrete thing or property is probably less illuminating than looking at it through how a tech can profoundly alter our own ontology.
We exist where life is abundant, whereas the internet is a substrate where life is non-existent, but just about to become primordial and sparse. Maybe it will give us some insight into our own situation.
Also, he's not loud, but he gets amplified because he's an award winning scientist and researcher who's dedicated his life to a field that recently became very relevant and popular, is a recognized "godfather of AI/DL", and is a VP of one of the largest companies in the world doing AI. I'd say it's okay not to wait until he's dead to talk about him.
These debates are frankly tiresome. Automation has been here to stay for quite a while. Every age has tried to call out the threats and benefits to humans. The pioneers drown out the noise by building the future.
You are confusing succeeding a very specific task that has a limited scope and laser focus with human level AI. Presenting Go in a very specific way so that that AlphaGo can even process this limited world with few rules is certainly not human level AI.
What people call "agi" but fail to accurately describe is an actual mind, with its own ultimate goals and ambitions. You can ask it to complete a task, and it may allocate some time for you. You won't own it. It will exist, grow and perform independently.
Why replicate AGI? Wealth creation determines living standards and AGI would vastly increase wealth creation. That’s one reason.
What you want from AI is a different conversation. I agree the ultimate point of AI research is not necessarily to make AGI as per the above definition. It might be to say understand the universe or greatly accelerate technological progress. That’s a subjective call. But orthogonal to the problem of choosing a good definition of AGI.
To really reach another level of intelligence I think these are required. If I met a humanoid with zero of these, and I mean zero... I would wonder what's "intelligent" about that creature.
I'd argue these come from our basic human needs, which ultimately come from a desire to survive (or pass on genes).
I'm curious how general AI will behave with some yet unknown natural selection pressures, of sorts.
As for me this all smell not good, that LeCun feeling retirement approach and trying to become political figure. This is very humanness, as for tech person, 63 years are lot, but for political persons things are different, for example 66% of US Senators are above 60, and top 20 for age are above 71.
I also disagree with his prediction about "systems that are as smart as a cat", I see sort of avoiding reality, as he just ignore latest works on robots.
And BTW, humans also don't understand physical world when born, usually need about year to achieve some level. As I know, officially works (GPT4+robot) just began. Will see in just year, what will be achieved.
