I'm confused how the world itself works - or would work - at scale. Taking that minecraft clip on the link, if I jump down a cave first, and the model decides the cave goes off to the left. A few hours later I come back, and this time the model decides the cave bends to the right?

I don't think it's a great approach for an actual game. In this case they're demonstrating that the model can create a shared space that's consistent for many players/users, for a short time. But like you say it would probably not endure.

Although it does put me in mind of playing daggerfall years ago, which had randomly generated dungeons that didn't always work. You could sometimes get trapped in architecture, jump from a height with no way to climb back up again. There was a reason Bethesda moved away from that
