Supporting other languages in the dev community is hard though. In my mind it kinda creates a split in the community, so one would need members that speak both languages well and glue the communities together.

I think this is a bulk of the hard work that most people in a similar position to me can do (though I only know english and a littttle bit of spanish, but I am referencing my perspective not my life skills). It is hard work, it takes constant people skills and people management. However, I also think the product of that work will undoubtedly have a force multiplication effect on the future growth of the fediverse to more diverse contexts, communities and languages.

As a thought experiment, lets dial this line of thought all the way up to 11. The fediverse would be perfect for hosting say a mastodon instance where all the communication is in a particular endangered language. The community could begin as a place to use an endangered language in conversation, and thus a great place to read and learn the language as well. It could also be a hub for information about classes and events related to the language as well. I believe there is already an Esperanto lemmy community on the fediverse, which is something along vaguely similar lines. Think about it, if somebody with the knowledge, time and skill to set up a lemmy or mastodon instance contacted a teacher conducting classes for an endangered language and offered to set up a community on their lemmy/mastodon server (or help set one up with the intention of handing over control eventually to people in that language community) wouldn’t the result be in many ways simpler from that language teachers perspective than trying to hack something together with commercial software? I think along many metrics it would.

Sure, a companies product for that would be slicker but what about custom character support for languages, what about autocorrect for that language built into the lemmy/mastodon server, what about specific features that are critical to the nature of the language, what about moderation policies that take into account the current and historical experience of the people who kept the language alive? Is a massive corporation run by a bunch of astronomically naive techbros mostly from california really going to care about meaningfully prioritizing implementing features for niche communities like this? …maybe sometimes??

I am disappointed people immediately attacked the details of my question, and focused mostly on the difficulties of constructing any kind of answer that meaningfully predicts the future of an incredibly complex intersection of variables… instead of taking my invitation to think broadly about the future of the fediverse and what the biggest, more direct actions that we can all take to help it grow and become more diverse.
