   LeCun also said back in 2022 that "if you train a machine, as powerful as it could be, your 'GPT-5000', on text", it will never be able to learn basic common-sense physics like that objects placed on tables will move along with them.

      You're missing the point here. He's not talking about whether or not they can learn facts or inferences derived from the text itself, but the more holistic intuition that results from learning from something like an embodied experience in the physical world. GPT-6 Astras web demo homepage thing is an example. It chose euclidean rather than quaternion for letting a user rotate the galaxy thing, and anyone who has ever used hands to rotate something would immediately recognize on trying it that something is fucked and you shouldnt do that. Thats the kind of common sense physics that is inherently beyond these llms and I run into it ALL the time in vr programming.

         Yup it lacks common sense because it doesn’t ‘understand’ reality - how could it? It doesn’t touch it like we do everyday. It has access to what is a model of reality via data.

         The good designer understands culture, tastes and preferences as they evolve in real time. That’s why llm as design tools haven’t displaced the good designers.

            Understanding of reality comes in many forms.

            We don't see in UV or infrared, but some birds do.

            On the other hand, AI can understand reality in ways we individually can't: It has combined access to unlimited knowledge of math, physics and chemistry that at this point no single human possesses. Maybe it understands reality better than any single human at this point.

            Also we're seeing AI reason from first principles in order to simulate physics and get to that real world understanding without directly interacting with it.
