I actually think elixir is the perfect boring technology now. The language is matured, and is not changing much. There will be a big addition at some point with the new type system, but other than that the language is pretty much done. Underneath elixir is erlang, which is extremely mature and highly boring in the good way. Live view might be the only exception, but even that is now becoming boring as it has gotten stable. If you are a believer in boring, you should definitely give elixir a try
