I'm commenting from the perspective of someone with zero experience with Elixir and Erlang. I've heard of them, but not used them.
So, I leafed through this document, and did not see how it would help people sell Elixir. Engineers will not be offered reasons to prefer it to other languages (popular or otherwise), and managers / bean-counters will not be convinced by the claims of it being less risky and a robust choice for a glue language - when very few people know it, so maintaining the elixir code will depend on some local guru and/or training people to use elixir.
... and this all is not to disparage Elixir! I just don't feel I've been told almost anything about it.
This was written to talk to people already in the community, as a way to explain the current situation. It was not targeted at external people that discovers it. We do have multiple other places for that if you are interested though :)
