Erlang/Elixir is a very neat little ecosystem, but in a lot of ways it's a dead end now. It was alone in its space for so long that it built a lot of ways of doing things that are kinda closed in on its own ecosystem, because there was no other ecosystem to reach out to to speak of, but now there's an abundance of choices and choosing Erlang means choosing something that is built on a lot of assumptions that don't match the world anymore. There may be some "reinvention" in building something on WASM and other communication mechanisms, but it's one with a path forward.
In particular, Erlang/Elixir have a lot of integrated solutions for modern code problems, but being either first or very early, none of them are best-of-breed anymore. You could think of them as the first draft of a lot of modern techs. Between that, and the fact that you can't build a business based on going to your customers and saying "Hey, everyone, I've got a great platform, just allocate the budget to rewrite your entire codebase into this somewhat obscure language and we'll make everything all better!", it just isn't a viable choice for a business, or at least not one that has any plans for growth. (And I don't mean VC-funded hypergrowth... I mean, the regular kind too.)
