underlying all three of those areas or business verticals is this idea of real world intelligence. really helped me understand what that truly means. 

Like, does that mean simulation? You know, really break it down for me. Yes, the way to think about a world model is a simulation engine that can predict what's going to happen next. 

So when you think about video models today, they can capture things like motion, the physics of things, but you're kind of just like watching something. 

World models take things a step further where you can interact with that environment And the future we're excited about is you can generate a world that you can interact with on demand.
