They've gone as far as making 1 in 8 tracks at Erlang Factory about Elixir. They had José give a keynote last year and participate on a panel this year. Robert Virding (one of the creators of Erlang) is fairly active in monitoring (and participating) in the elixir mailing lists. Granted, there's always a small tone of "get off my lawn", but that's just entertaining :-).

I've mentioned this before but I'll daybit again. Protocols and Macros are the game changer. The Enumerable protocol absolutely changes the way you write code and solve problems. Doing the same thing in Erlang is just not the same.
