Haha, despite the 1000s of instances where it DOESNT simulate correctly. Very specifically chosen 10000-shot generated videos show somewhat impressive fluid physics... And even then, it MUST be something it's seen before. Diffusion is in NO way modeling physics in a realistic matter, there is not an infinite amount of training data to show all fluid dynamics...
Now I know you're too far down the hype rabbit hole. Either that, or you lack a cursory understanding of diffusion models.
They do a better job of fluid sim than most human efforts to date. And that's just one of thousands of things they do better than our math.
