Anyone remember that one time, a year or so ago, when some company teased a physics based generative model which showcased a drop of water sliding down a beer bottle and the model could display the forces acting on it?

Whatever happened to that? Vapourware?

I think you mean this: https://genesis-embodied-ai.github.io/ It seems that this is much more focused on robotics, but interesting nonetheless.

Genesis is also a traditional physics engine, no ML-based physics prediction going on here. To my understanding their performance gains mainly come from building the engine to be highly parallelizable.
