Fuck AI

Not much, llm's and other gen ai crashing and burning change nothing about the fact that ML in general is doing crazy shit. Protein folding getting solved in our lifetimes is insane and there are still way more legit applications, nvidia will be fine.

Id imagine nothing but we all get cheaper GPUs on a overstock sale for a bit.

Many people in the world, they don't know the difference between an expert system and an LLM. Or, to phrase it a different way, many people think that AI is equivalent to generative AI.

I think that's largely a result of marketing bullshit and terrible reporting. Of course it would be good if people could educate themselves, but to some degree we expect that the newspaper won't totally fail us, and then when it does, people just don't realize they got played.

On a personal note, I'm a teacher, and some of my colleagues are furious that our students are using grammar checkers because they think grammar checkers are AI, and they think grammar checkers were invented in the last 3 years. It's really wild because some of these colleagues are otherwise smart people who I'm certain have personal experience with Microsoft Word 20 years ago, but they've blocked it out of their mind, because somehow they're afraid that all AI is evil.

They got very good results with just making the model bigger and train it on more data. It started doing stuff that was not programmed in the thing at all, like writing songs and having conversations, the sort of thing nobody expected an autocomplete to do. The reasoning was that if they keep making it bigger and feed it even more days, that the line would keep going up. The the fanboys believed it, investors believed it and many business leaders believed it. Until they ran out of data and datacenters.

Because that's how they're marketed and hyped. "The next version of ChatGPT will be smarter than a Nobel laureate" etc. This article is an indictment of the claims these companies make.

My running theory is that human evolution developed a heuristic in our brains that associates language sophistication with general intelligence, and especially with humanity. The very fact that LLMs are so good at composing sophisticated sentences triggers this heuristic and makes people anthropomorphize them far more than other kinds of AI, so they ascribe more capability to them than evidence justifies.

I actually think this may explain some earlier reporting of some weird behavior of AI researchers as well. I seem to recall reports of Google researchers believing they had created sentient AI (a quick search produced this article). The researcher was fooled by his own AI not because he drank the Koolaid, but because he fell prey to this neural heuristic that's in all of us.

If you're not yet familiar with Ed Zitron, I think you'd enjoy either his newsletter or his podcast (or both).

But how will you be able to auto-complete this "2 sentences long email" to your team at work without killing humanity?

it will once all the VC funds dries up, and the companies desparetely staving off that debt by enshittifying that service.

First you take the Shrek and the cabbage, you leave Shrek and Return for the Wolf. You leave the cabbage and take the Wolf. Now you take Shrek to the cabbage and bring both to the wolf. Now you row into the sunset, your work here is done.

Now do it for a stack of 12.

A research paper by Apple has taken the tech world by storm, all but eviscerating the popular notion that large language models (LLMs, and their newest variant, LRMs, large reasoning models) are able to reason reliably. Some are shocked by it, some are not. The well-known venture capitalist Josh Wolfe went so far as to post on X that “Apple [had] just GaryMarcus’d LLM reasoning ability” – coining a new verb (and a compliment to me), referring to “the act of critically exposing or debunking the overhyped capabilities of artificial intelligence … by highlighting their limitations in reasoning, understanding, or general intelligence”.

Apple did this by showing that leading models such as ChatGPT, Claude and Deepseek may “look smart – but when complexity rises, they collapse”. In short, these models are very good at a kind of pattern recognition, but often fail when they encounter novelty that forces them beyond the limits of their training, despite being, as the paper notes, “explicitly designed for reasoning tasks”.

As discussed later, there is a loose end that the paper doesn’t tie up, but on the whole, its force is undeniable. So much so that LLM advocates are already partly conceding the blow while hinting at, or at least hoping for, happier futures ahead.

In many ways the paper echoes and amplifies an argument that I have been making since 1998: neural networks of various kinds can generalise within a distribution of data they are exposed to, but their generalisations tend to break down beyond that distribution. A simple example of this is that I once trained an older model to solve a very basic mathematical equation using only even-numbered training data. The model was able to generalise a little bit: solve for even numbers it hadn’t seen before, but unable to do so for problems where the answer was an odd number.

More than a quarter of a century later, when a task is close to the training data, these systems work pretty well. But as they stray further away from that data, they often break down, as they did in the Apple paper’s more stringent tests. Such limits arguably remain the single most important serious weakness in LLMs.

The hope, as always, has been that “scaling” the models by making them bigger, would solve these problems. The new Apple paper resoundingly rebuts these hopes. They challenged some of the latest, greatest, most expensive models with classic puzzles, such as the Tower of Hanoi – and found that deep problems lingered. Combined with numerous hugely expensive failures in efforts to build GPT-5 level systems, this is very bad news.

The Tower of Hanoi is a classic game with three pegs and multiple discs, in which you need to move all the discs on the left peg to the right peg, never stacking a larger disc on top of a smaller one. With practice, though, a bright (and patient) seven-year-old can do it.

What Apple found was that leading generative models could barely do seven discs, getting less than 80% accuracy, and pretty much can’t get scenarios with eight discs correct at all. It is truly embarrassing that LLMs cannot reliably solve Hanoi.

And, as the paper’s co-lead-author Iman Mirzadeh told me via DM, “it’s not just about ‘solving’ the puzzle. We have an experiment where we give the solution algorithm to the model, and [the model still failed] … based on what we observe from their thoughts, their process is not logical and intelligent”.

The new paper also echoes and amplifies several arguments that Arizona State University computer scientist Subbarao Kambhampati has been making about the newly popular LRMs. He has observed that people tend to anthropomorphise these systems, to assume they use something resembling “steps a human might take when solving a challenging problem”. And he has previously shown that in fact they have the same kind of problem that Apple documents.

If you can’t use a billion-dollar AI system to solve a problem that Herb Simon (one of the actual godfathers of AI) solved with classical (but out of fashion) AI techniques in 1957, the chances that models such as Claude or o3 are going to reach artificial general intelligence (AGI) seem truly remote.

So what’s the loose thread that I warn you about? Well, humans aren’t perfect either. On a puzzle like Hanoi, ordinary humans actually have a bunch of (well-known) limits that somewhat parallel what the Apple team discovered. Many (not all) humans screw up on versions of the Tower of Hanoi with eight discs.

But look, that’s why we invented computers, and for that matter calculators: to reliably compute solutions to large, tedious problems. AGI shouldn’t be about perfectly replicating a human, it should be about combining the best of both worlds; human adaptiveness with computational brute force and reliability. We don’t want an AGI that fails to “carry the one” in basic arithmetic just because sometimes humans do.

Whenever people ask me why I actually like AI (contrary to the widespread myth that I am against it), and think that future forms of AI (though not necessarily generative AI systems such as LLMs) may ultimately be of great benefit to humanity, I point to the advances in science and technology we might make if we could combine the causal reasoning abilities of our best scientists with the sheer compute power of modern digital computers.

What the Apple paper shows, most fundamentally, regardless of how you define AGI, is that these LLMs that have generated so much hype are no substitute for good, well-specified conventional algorithms. (They also can’t play chess as well as conventional algorithms, can’t fold proteins like special-purpose neurosymbolic hybrids, can’t run databases as well as conventional databases, etc.)

What this means for business is that you can’t simply drop o3 or Claude into some complex problem and expect them to work reliably. What it means for society is that we can never fully trust generative AI; its outputs are just too hit-or-miss.

One of the most striking findings in the new paper was that an LLM may well work in an easy test set (such as Hanoi with four discs) and seduce you into thinking it has built a proper, generalisable solution when it has not.

To be sure, LLMs will continue to have their uses, especially for coding and brainstorming and writing, with humans in the loop.

But anybody who thinks LLMs are a direct route to the sort of AGI that could fundamentally transform society for the good is kidding themselves.
