Elixir was dropped from the 2020 Stackoverflow survey due to lack of usage (it was there in 2019). In Tiobe index Elixir isn't in the top 45. Jobs aren't that plentiful. Seems like as a community Elixir needs to use alternative measures ("Elixir Forum") because the conventional measures don't look good. And saying Elixir may become a popular option for ML is beyond wishful thinking.
