How often do things in the real world not behave exactly as you expected them to?

I feeling I get from this is that this could be the mental model for a robot in the real world, continuously corrected by actual events.

We all have a world model in our heads of what we think is going to happen, we adjust quickly (or not) based on what does. This is pretty incredible stuff.

Busts rarely hang in midair at a 45° angle.

As an aside, why fall into the role of being an apologist for google-hype and Big Tech?

You're missing the forest for the trees. The less than amazing physics isn't the point.

When you have a conversation, you have an idea in your mind of how the conversation is going to go. You predict what the other person is going to say before they say it.

When you are driving, you predict what the other drivers are going to do, you predict what signs say, how long you have until the green. If you see two red lights attached to the back of a car flash on, you may predict that the car is about to slow down and you start slowing down before their speed has changed.

Forget video games and movies. I believe these models will be that inner predictive model for robots.

Everyone already knows this, using these systems to create synthetic data to create more models is the primary driver for world model technology.

They wouldn't be called "Laws of Physics" if obeying them was optional. If your center of gravity is outside your base, you _will_ topple over. That's just how gravity works.

Your expectation is the point, not the physics. I'm not arguing that their model has an amazing grasp of physics. I'm arguing that this can be used as a predictive internal model for a robot.

I hear you, but my objection comes from the stress on "realism" in Google's post: how Genie4 is modeling the "real world" so well. If they didn't crow so much about realism, I wouldn't have cared as much.
