Elixir in Action has a section on pretty much this exact question. In it @sasajuric explains the benefit of how much less boilerplate code there is in Elixir. On one level it’s built-in niceties like GenServer, but Elixir goes further by giving you a rich macros system for layering on your own abstracts, like ExActor does. (This is a crude summary of the book. It goes into more details and covers other benefits.)
