My impression of this comment is that it is overgeneralizing, reductive, and pretty nihilist. That being said I do agree that minority languages, like our lives, are ultimately, in the fate of the great cosmic void, meaningless. But no, minority languages aren’t completely useless. Every language is a window into the structure of human language, which is something we are still trying to understand. Some people might tell you that sort of linguistics is also useless, but that’s a different conversation.

I would compare it to the sad loss of knowledge that results from another animal species going extinct. There are secrets in its genome that we will now never discover.
