The Elixir syntax is quite alike to Ruby's, so if you are going to change from Ruby to a language running on the Beam VM, switching to Elixir is easier than to Erlang because you don't have to relearn as much. I suppose that this effect is missing for Python to Elixir and that therefore relatively more people choose to switch to Erlang.
