I am using elixir for a very important part of a project where I work. The project leader who is giving up their repsonsibility over a half-baked python/django effort that is currently in prod asked me if it's risky because we're increasing our exposure by using a product that is not battle tested. Then i told him that our at work documentation (slab) and our soon-to-be site reliability early warning system (pagerduty) oh yeah and our corporate card (divvy) all are or Elixir/Phoenix so we already have exposure to the risks in adopting it.
