> that to understand knowledge you have to have a model of the world.
You have a small but important mistake. It's to
recite (or even
apply) knowledge. To
understand does actually require a world model.
Think of it this way: can you pass a test without understanding the test material? Certainly we all saw people we thought were idiots do well in class while we've also seen people we thought were geniuses fail. The test and understanding usually correlates but it's not perfect, right?
The reason I say understanding requires a world model (and I would not say LLMs understand) is because to understand you have to be able to detail things. Look at physics, or the far more detail oriented math. Physicists don't conclude things just off of experimental results. It's an important part, but not the whole story. They also write equations, ones which are counterfactual. You can call this compression if you want (I would and do), but it's only that because of the generalization. But it also only has that power because of the details and nuance.
With AI many of these people have been screaming for years (check my history) that what we're doing won't get us all the way there. Not because we want to stop the progress, but because we wanted to ensure continued and accelerate progress. We knew the limits and were saying "let's try to get ahead of this problem" but were told "that'll never be a problem. And if it is, we'll deal with it when we deal with it." It's why Chollet made the claim that LLMs have actually held AI progress back. Because the story that was sold was "AGI is solved, we just need to scale" (i.e. more money). I do still wonder how different things would be if those of us pushing back were able to continue and scale our works (research isn't free, so yes, people did stop us). We always had the math to show that scale wasn't enough, but it's easy to say "you don't need math" when you can see progress. The math never said no progress nor no acceleration, the math said there's a wall and it's easier to adjust now than when we're closer and moving faster. Sadly I don't think we'll ever shift the money over. We still evaluate success weirdly. Successful predictions don't matter. You're still heralded if you made a lot of money in VR and Bitcoin, right?
