Also it depends on the system you are building. Elixir and Erlang scale great and send messages even between servers fast! So if you need to scale it is great.

Also it depends on the system you are building. Elixir and Erlang scale great and send messages even between servers fast! So if you need to scale it is great. Go I am sure is faster performance wiz but Elixir/Erlang will stay running longer and be easier to reason about as the system gets bigger. Go will be easier to find devs then Elixir/Erlang will be harder. So there are trade offs. In the end you could use both, use the right tool for the job.
