> It is jaw-dropping and dismaying how for-profit AI companies use long-standing terms like "world model" and "physics" when they mean "video game model" and "video game physics." Or, as you can plainly see, "models gravity" when they mean "models Red Dead Redemption 2's gravity function, along with its cinematic lighting effects and Rockstar's distinctively weighty animations." Which is to say Google is not modeling gravity at all. That's because it's using video game data for training footage because it's cheap and easy to generate. It would not be simulating video game gravity if it was training on real world video inputs.
