This corresponds to the limits of combining symbolic and connectionist approaches, where it's impossible to create an ontology of the whole world and it's impossible to automatically generate all the explicit concepts we need for reasoning.

I suspect there is a Heisenberg-like law that limits how explicit concepts can be and how many can be used.

World models are clearly missing in current LLMs as @ylecun says but it’s unclear how future model architectures will balance useful emergent representations of the world with explicit concepts that are understandable to humans. https://t.co/9DUTl9fSrL

Interesting that Adam Brown anticipates LLMs will have Einstein-level intelligence in 10 years, but explains that at the moment physicists (like most of us) mainly use LLMs to search for and explain information and theories that are well known in the literature

Excellent thread by @fchollet about the performances of the new model by OpenAI on ARC-AGI. Evaluation dataset creation is an interesting challenge and is also a never-ending task: my guess is that we will always be able to design problems easy for humans and hard for machines.

Today OpenAI announced o3, its next-gen reasoning model. We've worked with OpenAI to test it on ARC-AGI, and we believe it represents a significant breakthrough in getting AI to adapt to novel tasks. It scores 75.7% on the semi-private eval in low-compute mode (for $20 per task

As usual, @fchollet gives the clearest and most synthetic explanations about the capabilities of LLM. Everything is said, really!

The question of whether LLMs can reason is, in many ways, the wrong question. The more interesting question is whether they are limited to memorization / interpolative retrieval, or whether they can adapt to novelty beyond what they know. (They can't, at least until you start

if biology can do it, I don't see why silicon can't do it (@davidchalmers42). A usual argument for considering that there is no fundamental difference between humans and machines. Rather weak. Consciousness exists in life, can you re-create life? Can you recreate the universe?

David Chalmers says it is possible for an AI system to be conscious because the brain itself is a machine that produces consciousness, so we know this is possible in principle

If you're working on ARC-AGI, you should take a look at Sebastien Ferre's approach. It feels conceptually closer to human reasoning, compared to other program synthesis methods. https://t.co/Zqxl9Mr44R
