In his book 'The myth of AI' (2021), Erik Larson argued that it is precisely the pursuit of Big Data(sets) that has been hindering real progress towards AGI. Interesting to see this convergent argument.

Hi Gary are you going to write about Devin? Quite a few people saying its a scam in the last few days.

Anyone who worked with neural networks could have predicted this. also after reading the comment section, what is it about AI that seems to bring out the crazy pseudophilosophers out in force? I swear AI sphere used to be math nerds arguing about statistical modelling of reality, now its mostly people who failed remedial math yelling about chatGPT and how it solved a riddle they copied from google.

I should have used "no more than" for clarity. My intended point, such as it was, was that you don't get an emergent property by simply making a bigger version of an inherently limited system. Reinforcing what Greg wrote. Thanks for the observation, they always help me clarify my own thoughts :-)

But weren't the scaling laws already saying that the performance increases as a logarithmic function of the data? What is new in this paper exactly? The title sounds like a statement of the scaling laws. I am confused.

I know you’re joking, but even in chaos there is structure. To be able to correctly model an idiot, you will quite likely have to understand the fundamentals of every human, idiot or not.

Not quite, that's what's required to model *all* idiots, exhaustively.

Plus, simply making epistemically unsound claims is modelling all idiots, except we've adopted a different, much nicer sounding term: people.

Ok, so LLMs can't do this, and can't do that. Seems reasonable, nothing in all of reality can do everything. So until further notice, we could talk about what LLMs can do, and how we can put those features to best use.

There are a ton of use cases where LLM use requires no supervision because it doesn't matter if the output is wrong some of the time. It's just that most of them are unethical.

There's been an explosion of LLMs being used in email scams, for example. LLMs require no supervision here, because it literally doesn't matter if the output is whack now and then. The LLM is generating emails to spam out for lead generation. If a few people get incoherent emails, there are zero reasons for the scammers to care. And if the LLM "hallucinates" -- well, so what? The whole scam was a lie to begin with.

But if you care about the people or result you're generating outputs for, it's hard to find a scalable use case for LLMs, because they need human supervision.

Expand full comment

The uses for LLMs are cases where a human is reviewing the output and the consequences for failure are small.

I need a vassalage or diabolical contract for a D&D campaign? It does it right, oh, 90% of the time -- unacceptable for an actual legal firm, but I can eyeball it, and if there's an error I miss (and one of my players is an insurance agent playing a high-intelligence charlatan PC, so it happens), I'll laugh and pretend I added the loophole intentionally for plot.

AI image generation? It usually takes a few tries to get right, but it'll give me a good-enough image to make an NPC token out of in a rush.

Programming? I know how to program; I can debug what it spits out, and only ask it for at most a single method at a time. Usually it's just stuff like LINQ -> SQL or SQL -> LINQ...

Point is, LLM use cases exist. They simply require too much babysitting to scale.

Here is a list of all the things they can do reliably:

When you consider how dumb the internet has made the actual people of the world, why does anyone think pouring more and more of the internet into these machines will make them intelligent?

I believe that will at least make them capable of intelligence, though some coding on top is needed to finish the job.

Garbage in, garbage out. Good point.

THE PLAN - Step #1: Take the output of a species which has thousands of massive hydrogen bombs aimed down it's own throat, an ever present existential threat it rarely finds interesting enough to discuss, and use that output to create a hyper intelligent machine.

THE PLAN - Step #2: Be absolutely amazed when that doesn't work.

Planning to fail seems suboptimal.

Why are humans so pessimistic sometimes? Could that have something to do with why so many things suck so bad so unnecessarily? 🤔

It might be because unlike in video games, you can only die one time.

Wasting that opportunity on Boeing jets or Tesla FSD seems like a poor choice.

How much can this be improved by changing the structure of the network and the training regimen, though? I know it's not directly comparable, but it seems a little odd that state of the art LLMs have an order of magnitude more parameters than we have neurons in our skulls, and have been trained on vastly more knowledge than any human could ever read, yet are still so relatively dumb.

Humans aren't able to detect how dumb they are because they cover it up with language, culture, (sub)consciousness, unrealized irony, etc.

Expand full comment

It’s not even a little bit odd. The parameters and “neurons” in artificial neural networks are just way less dynamic than actual neurons in the brain, with much fewer regulatory mechanisms that can alter their output depending on the input. In the brain, as someone pointed out below, there are also astrocytes(glia) which have their own network and send out processes that wrap around every single synapse (actual synapses are tripartite: preseynaptic neuron, postsynaptic neuron, astrocyte), and can modulate the output of the presynaptic neuron and the input the postsynaptic neuron receives, based on state changes in the astrocyte network that can be triggered by different neuronal circuits that could be far away.

Additionally, within each neuron, there’s a lot more going on that summing the inputs and giving out an output if a threshold is reached.

Essentially, the dimensionality of data captured in the brain is vaster, even though the amount of data the brain can be trained on is far lower than an artificial network. This allows the brain to generalize much better, and, of course, do it all consuming minuscule amounts of energy compared to LLMs.

Expand full comment

Is this an exhaustive and accurate description of the reason?

Expand full comment

Accurate to our current understanding, yes. Most definitely not exhaustive. If LLMs are a black box, our brains are, currently, blacker boxes, becuase there's just a lot more we don't know about even the fundamental building blocks, let alone the ways they interact to give rise to consciousness, cognition and sentience.

Expand full comment

> Accurate to our current understanding, yes.

Your "understanding" of our current understanding.

And while it's true that we do not understand the materialistic implementation of consciousness, we know A LOT about its phenomenological nature (we mostly just ignore what we know), which is far more important.

BTW, in neurobiology, a glial meshwork has a primary role and controls the functioning of a neural network. Similarly, a semantic multilingual model has a central role and uses a statistical multilingual model for word forms generation.

So now we're saying it has to be reliable before we count it as general intelligence? (Nothing against reliability but it isn't what proves a concept, especially a concept such as general intelligence.) I agree with this technical sentiment that LLMs when overfitted, untuned, and unaugmented with other vectors, are messed up to use in general and not intelligent. For some of these LLM wrapper type apps, It's kind of like using a bell curve when a flow chart would make more sense logically. Sure, we totally need more than just LLMs, but that's what AI has been since before the internet. A bunch of non-LLM non-transformer type AI technology that doesn't rely on pretrained models. So we have AGI it's just not superintelligent. We've already done it. I would even summarize your whole argument as "I wish AGI wasn't so general that it's unreliable. Now let's do some real AI stuff besides just pretrained transformers ad nauseum."

please read the article i linked today. what we have now is a giant memorization machine that becomes unreliable for anything far enough beyond its training set.

You are describing your subconscious, *sub-perceptual* (thus invisible) model of the thing, not the thing itself.

What we have now is not known and likely unknowable at least for now. Perhaps if we clean up our thinking and language we can get closer!

Sure if everything we're calling AGI is just LLMs (but there is so much more).

I don't know what AGI you may or may not be using to guess or know that I didn't read the research paper or synopsis you linked when I made my comment earlier, but you are right I didn't read it until now.

By the way I mostly read your articles not the ones you link and in general I like what you have to say even though I'm on a low sodium diet and things are starting to sound a bit salty when it comes to these hype cycles. (not just you a lot of people I read on substack).

Nothing I said changes though. It's because the article you linked is specifically criticizing the hype around zero-shot which again is one specific (wrong) explanation of the AGI state we have already achieved. The real AGI started with http protocol.

We're passionate about AI but I don't see the point in playing word games unless we're gonna get into the actual philosophy underlying some of these popular semantics.

Playing work games in very particular ways is a good way to figure out how reality works.

Your mind plays a crucially important role in "not making sense", it simply fails to notify you of this, presumably for evolutionary reasons, and also for cultural reasons.

Absence of evidence is not evidence of absence.

Put differently: Just because ChatGPT gives one answer that is right doesn't proof that every answer is right.

The thing with cars and other machinery is: Without a credible fall-back mechanism, *one mistake* is enough to kill you.

It's called Musk's roulette.

Of course, OpenAI, Google, and friends are already aware of this, which is why they are engineering the hell *around* the models, instead of supersizing them or spend another three years on fine-tuning: GPT3 was already 175B in 2019. They fine-tuned it for three years to make it 'helpful, honest, harmless' and after launch in 2022 the jailbreaks were so bad that they had to resort to filtering (an admission of defeat) within months. Much more has been done, but sizing apparently not. https://ea.rna.nl/2024/02/07/the-department-of-engineering-the-hell-out-of-ai/

"in 2022 the jailbreaks were so bad [...]"

Indeed. Back in the days, hacking was about reverse engineering mistakes a human would make one step at a time - but with LLMs you just state your intentions in the weirdest, most twisted way imaginable (e.g. just repeat them a dozen or so times[1]) and bam, you get what you want.
