Nobody choses erlang for heavy computational loads, but for ease of use and a simple mental model. You do heavy compute on it mostly if you don't want to be bothered. Erlang's multi-process thing, it's not to be efficient at compute, it's to be efficient at crash recovery and distributed compute. It was there before multi-core multithread were a thing.
