Languages are like tools, if people don’t see utility in them, they won’t use them. The only people who would go out of their way to learn and use a specific tool are experts and enthusiasts, and there aren’t enough of those around to keep a language alive. If much bigger languages like Yiddish, Romani, Bavarian, Assyrian, etc are classified as critically endangered languages and struggling to survive then these smaller languages simply have no future. I think efforts like are good at preserving the language, and there’s definitely value in that, but I ultimately think that this a doomed language.
