Yeah, but both Go and Elixir (Erlang less so - commercial and internal PLs work a bit differently) were in the same situation at some point: very small ecosystem, small community, lots of changes to the language. Adopting a language at this stage of evolution has a set of very well-known risks, but it has to be done by someone for the language to ever reach maturity. Trying to use it seriously is one of the best ways to contribute to the language.

In any case, if you are aware of the risks and plan to mitigate them - by, for example, employing people capable of debugging and fixing the language's implementation - you're left with some risk and a lot of advantage (if you're lucky and your domain is indeed the one your language is best suited for). It's a gamble, of course, but then nearly every decision (other than buying IBM) is one.
