I'm aware of that. I'm not trying to say that having been oppressed had advantages for indigenous people, maybe rather that using the language of the oppressor to preserve knowledge means making the best out of a bad situation, and opens the knowledge for the world, which is an important and valuable contribution to common human knowledge.

At same time I immensely appreciate the diversity of thoughts that can arise out of a diversity of languages. By no means do I think we should impose a world language and make all other languages disappear. More of everybody being bilingual or multilingual by default, and an artificial language being one language used to communicate among larger groups of people, like English is now, but involving a larger group of people (and yeah, not being colonialiser-based would be great, maybe a completely new language would truly be better).

Being able to share a common language gives people power - we can share and relate to experiences from people all over the world, we can organize as human species.
