Eh, these days it's pretty easy to translate technical ideas between languages, so I doubt major breakthroughs are confined to the language they're discovered in. I think there probably is some siloing of more subtle cultural artifacts, but linguistic context of those artifacts may be part of why they're so valuable. This is a just a vague opinion, but I think different languages use really different idioms and concepts about how the world works. Having access to those idioms and concepts may have value in enabling lateral thinking. Someone with a slightly different conceptual toolset might approach a philosophical, political, or even technical problem in a different way and find new of useful solutions.
