Whoa, whoa, whoa. That's just one angle. Please don't bin that as the only use case for "world models"!

First of all, there are a variety of different types of world models. Simulation, video, static asset, etc. It's a loaded term, just as the use cases are widespread.

There are world models you can play in your browser inferred entirely by your CPU:

There are static asset generating world models, like WorldLabs' Marble. These are useful for video games, previz, and filmmaking.

I wrote open source software to leverage marble for filmmaking (I'm a filmmaker, and this tech is extremely useful for scene consistency):

There are playable video-oriented models, many of which are open source and will run on your 3080 and above:

Genie is not strictly robotics-oriented.
