The video was really well done, very interesting even though I’m not very familiar with the subject. Is this the sort of thing that would go into a game like No Man’s Sky to improve the planet generation?

In my opinion, any game featuring large-scale, realistic terrain would benefit from a tool like this. You simply can't hand-craft every ridge on a mountain range at that scale. Unless you're recreating a real-world location using satellite and LIDAR height data, procedural filters are the only way to achieve that level of geological detail efficiently.

I imagine lots of games do already, but offline. Most games don’t have gameplay that requires real-time terrain generation. The idea of generating terrain procedurally is not new, but this technique that gets a great-looking erosion effect in real time is.

The tools exists (AFAIK the defacto industry standard is World Creator: https://www.world-creator.com/en/index.phtml - this is for offline generation though)

Mountains weather directional, meaning rain comes mostly from one direction to press against the mountains and create gullies, so there is a rain shadows on "inner mountains" also there is weathering by gully freezing, so the thin ridges between gullies get freeze cracked to rubble. That rubble again builds up, almost filling the lower slopes of a gully ocassionally.

Finally there are invisible gullies, layers of rock where the water sips into the rock and caves, leaving all things below gully free.
