LeCun’s take on World Models

So....I read LeCun's interview with Nebius Science. I feel he had some cool points about LLMs being able to answer things, but not literally understand the physics of the physical world. (Like, being able to explain a task and actually performing it are two completely different things.) But I wanted to get opinions on what others thought of his solution to the problem. Like, if JEPA is genuinely the architectural solution to this, or if we’re just looking for some magic solution that we don't have the tech for yet
