Note that I wasn't asking why one would use Go instead of Elixir for a given task. If it's CPU bound, Go would be a better choice.

My question was how the poster was using Go with Elixir. Since they have a big overlap in what they're commonly used for and since NIFs (Natively Invoked Functions) on the BEAM really need to be fail-safe, it's not as clear as how to use these two together as how one would use C in the same stack with Python, for example.
