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)

PS: TIL that this is a German company: https://docs.world-creator.com/world-creator-story
