Personally, for me it was the other way around. Discovering Erlang (and Elixir) removed all uses of Go that I had. I primarily used Go for writing networked applications. I never needed crazy CPU throughput on a single point of execution. Erlang's way of modeling concurrency and the built-in facilities of OTP made me way more productive than re-inventing the wheel via channels.
