Are there any experts that could help me bootstrap myself on the current literature on "world models?"

In this current generation, "world models" is basically a marketing term. You can research gaussian splatting, novel view synthesis, neural radiance fields (nerf), etc... I find Mr Nerf is good to follow: https://x.com/janusch_patas

There is another thing called world models that involves predicting the state of something after some action. But this is a very very limited area of research. My understanding of this is that there just isn't much data of action->reaction.

Same issue with gaussian splatting/nerf really, very little data (relative to text/images/videos) of text -> 3d splats. I'd guess what world labs are doing is text -> image -> splats, but of course it is just speculation.

Folks interested in this can look up Yann LeCun's work on world models and JEPA, which his team at Meta created. This lecture is a nice summary of his thinking on this space and also why he isn't a fan of autoregressive LLMs: https://www.youtube.com/watch?v=yUmDRxV0krg
