Well it does, but it still doesn't do it efficiently. That was the only point I was making. But in general, yes, Elixir/Erlang will handle CPU bound tasks better than node whenever they can be effectively parallelized.
Well what I meant to say is that both JS and Elixir/Erlang aren't very efficient at using CPU resources. Elixir/Erlang does a better job at compensating for this by being able to run many operations in parallel and across different machines, which isn't something you can easily achieve (or should even attempt) with Node.
