Yeah probably, it remains to be seen if these models can actually help guide a live session towards the goal. At least it's been shown that these types of world models can help a model become better at achieving a goal, in lieu of a hard coded simulation environment or the real world, for when those options are not tractable.

My favorite example is: https://worldmodels.github.io/ (Not least of all because they actually simulate these simplified world models in your browser!)
