Here's the obligatory AI enthusiast answer:

What is physics besides next token/frame prediction? I'm not sure these videos deserve the label "inaccurate" as who's to judge what way of generating next tokens/frames is better? Even if you you judge the "physical" world to be "better", I think it's much more harmful to teach young children to be skeptical of AI as their futures will depend on integrating them in their lives. Also, with enough data, such models will not only match, but probably exceed "real-physics" models in quality, fidelity, and speed.
