World models are trivial. eg narratives are world models and they provide only pre frontal simulation, ie they are synthetically prey-predation. No animal uses world models for survival and doubtful they exist (maps are not models), a world model doesn't conform to optic flow, ie instantaneous use and response. Anything like a world model isn't shallow, the basic premise of oscillatory command, it's needlessly deep, nothing like brains. This is just a frontier hail-mary to the current age.
