We've been using Elixir almost exclusively for a couple years, and I can't speak highly enough about it. There are clearly problems where beam is ill-suited, but otherwise, I almost feel religious about it.
I've worked for many years with many other languages and runtimes, but beam, OTP and Elixir (and the synergy between them) are better tools. As a foundation, message passing and isolation are the only realistic weapons I've seen against most common causes of technical debt (coupling). It isn't a silver bullet, but it tries hard to help you. And, importantly, it's approachable.
Another way to look at it is that it delivers many of the same benefits of SOA/microservices, without the significant infrastructure/deploy/devops overhead.
