For example, here is a variation on the Observation, State, Action loop I was describing earlier. Here the observations and actions are messages from other language models, which are concurrently getting fine-tuned on text from the internet (though they are not getting fine-tuned in the attached image since it is just an example visualization).
You’re using LLMs trained on internet text. If that’s part of the plan, I don’t think you can say it’s “trained in a way that is analogous to a human childhood in all of the relevant ways”, nor can you say that imitation-learning-from-humans is not a central part of your story. Human children do not undergo autoregressive training from massive corpuses of internet text.
Internet-trained LLMs emit human-like outputs because they were trained by imitation-learning from lots and lots of human-created text. Humans emit human-like outputs because they are humans. These are not the same, right?
I am indeed talking about a particular set of designs for an AI, but these are designs which increase the extent to which they can be considered AIs, because they give them adaptive properties. So I don’t think the title is misleading.
I interpret you as saying:
I’m only interested in AIs that are very competent at staying alive, executing plans, etc.
If I make an AI as follows: [autoregressive training on a massive corpus of internet text, certain type of prompting, blah blah], then I will get an AI that is very competent at staying alive, executing plans, etc.
Therefore I need only be interested in AIs that look like the previous bullet point.
If so, it’s obviously a bad argument because it neglects the possibility that maybe there are also other very different ways to make an AI that is very competent at staying alive, executing plans, etc. And indeed this is the case: e.g., whatever happens in the brains of human children (since human children brains are not trained on a massive corpus of internet text, or prompted, etc.).

All we need is for the text streams have mutual information in order to train cooperation this way. In which case your claim is that human children do not undergo autoregressive training from massive corpuses of text, to which I respond that the modality of training data only matters insofar as it is entangled which the world and the content of others’ minds. Blind people are not barred from intelligence.

Ok, so while for any fixed bar of functionality there would be multiple models that would exceed that bar, I expect that in the limit competitive pressures will squeeze out anything that isn’t orthogonal to communication ability. I also suspect that the parts of human values that would survive the CEV are the ones that are downstream of communication.
So to your bullet points: 1) Yes, 2) Yes, 3) More like here is one of a handful of techniques that I can apply that will help increase the communication and therefore the prosociality of an LM
I note that I am using the word communication in a bit of a non-standard way—I mean number of bits sent as measured by the number of times it halves the receiver’s Bayesian uncertainty, as opposed to raw number of 0′s and 1′s sent on a wire.
your claim is that human children do not undergo autoregressive training from massive corpuses of text, to which I respond that the modality of training data only matters insofar as it is entangled which the world and the content of others’ minds.
A group of humans who have never been exposed to language, not in any modality, will develop a new grammatical language out of nothing, e.g. Nicaraguan Sign Language, or the invention of the earliest languages in prehistory.
So there is something going on in humans that is not autoregressive training-then-prompting at all, right? This isn’t about modality, it’s about AI paradigm. Autoregressive training will never create grammatical language out of thin air, right?
here is one of a handful of techniques that I can apply that will help increase the communication and therefore the prosociality of an LM
I feel like you should have said “here is one of a handful of techniques that I am aware of”. For example, do you think no more AI algorithms will ever be discovered in the future?
I also strongly disagree with “communication therefore prosociality” in general. I’ve known a couple high-functioning sociopaths, they communicated as much as anybody, indeed probably more than average.

Yet again, from my perspective, you seem to have a giant blind spot to the idea that any AI algorithm could possibly exist apart from autoregressive training then prompting. Human brains do a lot of things that are not autoregressive training, right? Particularly RL.
If a human or animal is hungry then they will eat because they find eating-when-hungry to be rewarding, i.e. thanks to an RL reward function, not because they were find-tuned on examples of themselves eating, nor because they were prompted to eat or whatever. Animals will eat when they’re hungry even if they have never seen any other animal eat before, not in any modality.
You’re welcome to specify that RL-centric algorithms are outside the scope of this blog post, but you can’t also say “an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways” if there is no online RL involved, right?

Meh. I could see the prompting and finetuning structure mentioned earlier giving rise to agents which figure out more efficient ways of communicating. If you asked GPT-4 to create a new language now it might be able to do it. Also for the record I am talking about reshaping the prompt during and not just after regular auto-regressive training.
I feel like you should have said “here is one of a handful of techniques that I am aware of”. For example, do you think no more AI algorithms will ever be discovered in the future?
Yes, I expect there to be many more techniques that increase the communication of the system that the AI is embedded in. My point is that this is how I am coming up with the ideas in the first place.
I also strongly disagree with “communication therefore prosociality” in general. I’ve known a couple high-functioning sociopaths, they communicated as much as anybody, indeed probably more than average.
Indeed, if they are not doing object-level bad things, which decrease the amount of communication in their environment, then I do not see anything wrong with them. Sociopathy will end up getting selected out of the population as a function of how much they decrease the communication of the process in which they are embedded (for example by being dishonest or hurting people), which is why we are not all sociopaths.

I did say auto-regressive training and prompting, right? I think decision transformer includes RL into the auto-regressive training + prompting story, but I could be wrong about that.
If you asked GPT-4 to create a new language now it might be able to do it.
GPT-4 has already been trained on lots of human language. Let’s talk instead about a transformer initialized with random weights (xavier initialization or whatever).
Starting right from the random xavier initialization, you are not allowed to (pre)train it on any human language at all. None. No text. No audio of humans speaking. No video of humans speaking. Absolutely none at all. Do you think that could wind up with grammatical language? If not, then I claim this is a nice demonstration (one of many) of how human child brains are doing something different than the kind of AI you have in mind.
I did say auto-regressive training and prompting, right?
Your OP doesn’t say “auto-regressive training & prompting”, rather it says “an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways”. I don’t think the kinds of AIs and training procedures that you have in mind are at all analogous to a human childhood. Children will do things that they want to do without being “prompted” by anyone. Children are not exposed to 45 TB of internet text while in the womb. Etc. Right??
I think decision transformer includes RL, but I could be wrong about that.
Is that what you’ve ben thinking of this whole time? You didn’t even mention decision transformers until just now. (Or did I miss it?)
Yes, I expect there to be many more techniques that increase the communication of the system that the AI is embedded in. My point is that this is how I am coming up with the ideas in the first place.
Let me put it this way. Suppose I understood how human brains worked sufficiently well that I could make an AI that was doing all the same things as a human child brain, for the same reasons, i.e. due to the same underlying algorithms. Then I put this AI in a human body and raise it in a loving human family.
From my perspective, this would be the most central example possible of “an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways”.
But from your perspective, I feel like you’re going to say “Oh no no no, that’s totally different from the thing I’m talking about in this post.”
(After all, human brains incorporate many features that do not increase the communication of the system that they are embedded in. Sociopathy has not been selected out of humans. Some human children are introverted and we’re OK with that. Etc. etc.)
If so, do you see why the post title & intro come across as misleading?

The LM does indeed start training with random initialization and has to learn new languages. So then the question is why are humans more sample efficient than LM’s? I am not sure about this, and I am not even sure of the premise. It sometimes feels like GPT-4 can read something once that I would need to read a few times. Which is to say that sample efficiency may be a function of how many tokens you have already seen (I would greatly appreciate a graph showing this). So it could be the case that humans are just a particular kind of pre-trained. But normally pre-training does include language, and babies don’t seem to be pre-seeded with the languages of their ancestors. So what can that pre-training contain? Well probably interaction with some sufficiently complex yet predictable environment that responds to their action space (tokens). Maybe you could do meta learning from this stage to create an LM which can learn a language from few samples. But even the smaller model may be difficult to encode directly in the genome, and it could be easier to specify parts of those models as a reward function, which when followed will lead to reconstructing those pre-trained models.
But your point here is that ML models are not like people in this way. Some other differences that I tentatively think currently exist are that LMs are faster than people, people are more sample efficient than LMs, and LMs tend to get stuck when making long term plans at the moment (try Auto GPT for instance).
I believe you are pointing out that there are differences in people and LMs to demonstrate that the space of competence intelligences is wide. The (admittedly rephrased) point I made in response to this earlier was that while there are many intelligences that are beyond some level of competence, I expect competitive pressures to ramp up as a function of intelligence (related). This is because I think that a system’s optimization ability (aka intelligence) is a monotonic function of its ability to communicate internally and externally (flagging that I am quantifying communication via Bayesian information). Optimization abilities scale with communication because communication allows you to recruit more computational resources for a given problem. Going back to the main point, I think that the design space of competitive intelligences will end up converging, and the only reason that it hasn’t sufficiently converged yet is that we are not smart enough.
Your OP doesn’t say “auto-regressive training & prompting”, rather it says “an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways”.

I did not go into detail about what I believed were the ‘relevant ways’ because I thought that talking about communication and such would be too philosophical and drag out the post. But I do understand that it might make the reader suspicious that I am circularly defining the ‘relevant ways’ in terms of humans. Of course, I need to use my baseline of humans in order to guess what future values might look like, in which case this is the same kind of circular as any scientific theory which uses data from the universe to predict other data from the universe.
Is that what you’ve ben thinking of this whole time? You didn’t even mention decision transformers until just now. (Or did I miss it?)

Yes, that would be a central example, and I would wish you the best of luck getting it done in time.
(After all, human brains incorporate many features that do not increase the communication of the system that they are embedded in. Sociopathy has not been selected out of humans. Some human children are introverted and we’re OK with that. Etc. etc.)
To say this you would have to argue that humans without this feature would have led a faster singularity, more or less. My point earlier with respect to sociopathy was that it is only selected out to the degree that it manifests in anti-social behavior. If your sociopath ends up producing some company that produces net value for organisms at various levels of abstraction, evolution counts that as a win. That introvert might invent the steam engine, letting people interact from farther away and extract more energy from their environment so you can make more people who start the cycle over again. Not that inventing the steam engine likely enough for evolution to pick it up specifically—I am just trying to say that the action spaces is much wider than the words that you verbalize.
If so, do you see why the post title & intro come across as misleading?
The antecedent has not been fulfilled if I am understanding what “if so” is pointing at correctly.
The LM does indeed start training with random initialization and has to learn new languages. So then the question is why are humans more sample efficient than LM’s?
No, that’s not the question I was asking. Humans are able to start using grammatical languages on the basis of no observations of grammatical language whatsoever—not in the pretraining, not in the training, not in text form, not in audio form, not in video form. Again, I mentioned Nicaraguan sign language, or the creation of creoles from pidgins, or for that matter in the original creation of language by hominins.
So this has nothing to do with sample-efficiency. There are zero samples.
I don’t think you can take one or more randomly-initialized transformers, and get grammatical language out of them, without ever putting any human-created grammatical language into them. Do you? If so, how?
To say this you would have to argue that humans without this feature would have led a faster singularity, more or less.
I’m sorry, I don’t understand this sentence at all.
Your post says “Let’s imagine a hypothetical scenario where an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways.” OK, now:
It is possible in principle to program an AI that is exactly like a human sociopath’s brain
It is possible in principle to put that AI in a human-like body and raise it in a loving human family in a normal human neighborhood, enroll them in school, etc.
Presumably, if I did both these things, this would be a central example of “a hypothetical scenario where an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways”, according to a reasonable interpretation of those words.
And if I did both these things, I would wind up creating an AI that is just like a human adult high-functioning sociopath, the kind of person that emotionally abuses people just for fun, with callous disregard for the well-being of anyone but themselves, that is constitutionally incapable of guilt or remorse, etc. etc.

I don’t think you can take one or more randomly-initialized transformers, and get grammatical language out of them, without ever putting any human-created grammatical language into them. Do you? If so, how?
I agree that my statements about sample efficiency do not address this point. I do think you could get transformers to invent language, without seeing language data. You would want to use online learning in an observation, state, action loop while interacting with an environment, and probably include optimizations from ReAct, Reflexion, AutoGPT, and Voyager. But each of these relies on having some core language model that can do reasoning, and the way that we normally get these is by pre-training on language. I could imagine instead on pre-training on solutions to another problem that is arbitrarily hard to compute, simple to verify, and provides a natural learning gradient. For example, the LM could be given a numpy program f and an output f(x) and get loss L2(f(x),f(y)) for guess y. Or it could try to guess zeros of polynomials and get loss and be penalized according to the guess squared. Then put the agents together in a way such that they can communicate through their input and output channels, and I suspect that they will be able to create language. Maybe language is not so hard—level 1 is just using words to point at concepts you already have. Then learning how to compose those words is just a matter of more time-steps, given sufficient parameter capacity in your networks.
To say this you would have to argue that humans without this feature would have led a faster singularity, more or less.
I am saying it is hard to know if a feature of a person gives rise to better communication in the whole group, which makes my theory conveniently hard to test. And then I am pointing at the singularity as a limiting object (from our point of view) of increasing communication, that follows in a trend after DNA, language, the printing press, phones, the internet, and AI.

Where if anywhere do you disagree?
For the bullets:
Agree, and I think that AI won’t last long in the world, but it might last long enough to destroy humans.
Agree
Agree
Thank you for bringing my post into an empirical domain I had not been thinking about. So I will modify my claim to ‘there exists a competence level α such that for all agents with competence level β>=α, nurture matters more than nature’, where ‘matters more than’ also needs to be made precise. Now the question is locating α, for which it would be useful for me to understand how common it is for a person to have a high quality upbringing (in a multi-faceted sense) and end up self-interested. Though I wonder if size of moral circle is the right metric.
I think people’s personalities are significantly predictable from their genes, and mostly independent of how their parents raised them (at least within the typical distribution, i.e. leaving aside cases of flagrant abuse and neglect etc.). See e.g. popular expositions of this theory by Judith Harris or by Bryan Caplan for the fine print and massive body of supporting evidence (e.g. twin studies and adoption studies). Antisocial personality disorder / sociopathy follows the usual pattern like everything else—it’s substantially predictable based on genes, almost entirely independent of how your parents raise you and other aspects of childhood family environment.
I’m not sure what you mean by “competence”. Mean people and cruel people and high-functioning sociopaths can be very highly “competent” according to how I use that word day-to-day. William Shockley was a brilliant physicist who started a successful company—while also being awful to everyone, vindictive, and a notorious racist. Heck, Hitler himself was extraordinarily charismatic and exquisitely skilled at social manipulation, AFAICT. He achieved one wildly ambitious goal after another. I think I would describe him as a “highly competent” guy.
You’re using LLMs trained on internet text.

Of course, I need to use my baseline of humans in order to guess what future values might look like, in which case this is the same kind of circular as any scientific theory which uses data from the universe to predict other data from the universe.
My proposal (linked again for convenience) and toolformer (in an earlier comment) also train auto-regressively on a modified prompt. I was including this when talking about auto-regressive training + prompting. This is what I was trying to communicate by saying “Also for the record I am talking about reshaping the prompt during and not just after regular auto-regressive training”.
Yes, that would be a central example, and I would wish you the best of luck getting it done in time.
To say this you would have to argue that humans without this feature would have led a faster singularity, more or less. My point earlier with respect to sociopathy was that it is only selected out to the degree that it manifests in anti-social behavior. If your sociopath ends up producing some company that produces net value for organisms at various levels of abstraction, evolution counts that as a win. That introvert might invent the steam engine, letting people interact from farther away and extract more energy from their environment so you can make more people who start the cycle over again. Not that inventing the steam engine likely enough for evolution to pick it up specifically—I am just trying to say that the action spaces is much wider than the words that you verbalize.
The antecedent has not been fulfilled if I am understanding what “if so” is pointing at correctly.
No, that’s not the question I was asking. Humans are able to start using grammatical languages on the basis of no observations of grammatical language whatsoever—not in the pretraining, not in the training, not in text form, not in audio form, not in video form. Again, I mentioned Nicaraguan sign language, or the creation of creoles from pidgins, or for that matter in the original creation of language by hominins.
So this has nothing to do with sample-efficiency. There are zero samples.
I don’t think you can take one or more randomly-initialized transformers, and get grammatical language out of them, without ever putting any human-created grammatical language into them. Do you? If so, how?
I’m sorry, I don’t understand this sentence at all.
Your post says “Let’s imagine a hypothetical scenario where an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways.” OK, now:
It is possible in principle to program an AI that is exactly like a human sociopath’s brain
It is possible in principle to put that AI in a human-like body and raise it in a loving human family in a normal human neighborhood, enroll them in school, etc.
Presumably, if I did both these things, this would be a central example of “a hypothetical scenario where an AI is somehow trained in a way that is analogous to a human childhood in all of the relevant ways”, according to a reasonable interpretation of those words.
And if I did both these things, I would wind up creating an AI that is just like a human adult high-functioning sociopath, the kind of person that emotionally abuses people just for fun, with callous disregard for the well-being of anyone but themselves, that is constitutionally incapable of guilt or remorse, etc. etc.
Where if anywhere do you disagree?
I agree that my statements about sample efficiency do not address this point. I do think you could get transformers to invent language, without seeing language data. You would want to use online learning in an observation, state, action loop while interacting with an environment, and probably include optimizations from ReAct, Reflexion, AutoGPT, and Voyager. But each of these relies on having some core language model that can do reasoning, and the way that we normally get these is by pre-training on language. I could imagine instead on pre-training on solutions to another problem that is arbitrarily hard to compute, simple to verify, and provides a natural learning gradient. For example, the LM could be given a numpy program f and an output f(x) and get loss L2(f(x),f(y)) for guess y. Or it could try to guess zeros of polynomials and get loss and be penalized according to the guess squared. Then put the agents together in a way such that they can communicate through their input and output channels, and I suspect that they will be able to create language. Maybe language is not so hard—level 1 is just using words to point at concepts you already have. Then learning how to compose those words is just a matter of more time-steps, given sufficient parameter capacity in your networks.
I am saying it is hard to know if a feature of a person gives rise to better communication in the whole group, which makes my theory conveniently hard to test. And then I am pointing at the singularity as a limiting object (from our point of view) of increasing communication, that follows in a trend after DNA, language, the printing press, phones, the internet, and AI.
For the bullets:
Agree, and I think that AI won’t last long in the world, but it might last long enough to destroy humans.
Agree

Thank you for bringing my post into an empirical domain I had not been thinking about. So I will modify my claim to ‘there exists a competence level α such that for all agents with competence level β>=α, nurture matters more than nature’, where ‘matters more than’ also needs to be made precise. Now the question is locating α, for which it would be useful for me to understand how common it is for a person to have a high quality upbringing (in a multi-faceted sense) and end up self-interested. Though I wonder if size of moral circle is the right metric.
Thanks!
I think people’s personalities are significantly predictable from their genes, and mostly independent of how their parents raised them (at least within the typical distribution, i.e. leaving aside cases of flagrant abuse and neglect etc.). See e.g. popular expositions of this theory by Judith Harris or by Bryan Caplan for the fine print and massive body of supporting evidence (e.g. twin studies and adoption studies). Antisocial personality disorder / sociopathy follows the usual pattern like everything else—it’s substantially predictable based on genes, almost entirely independent of how your parents raise you and other aspects of childhood family environment.
I’m not sure what you mean by “competence”. Mean people and cruel people and high-functioning sociopaths can be very highly “competent” according to how I use that word day-to-day. William Shockley was a brilliant physicist who started a successful company—while also being awful to everyone, vindictive, and a notorious racist. Heck, Hitler himself was extraordinarily charismatic and exquisitely skilled at social manipulation, AFAICT. He achieved one wildly ambitious goal after another. I think I would describe him as a “highly competent” guy.
