Yeah, they had 99 problems and a bad tech stack wasn't one of them. On a more serious note, Elixir is very good but suffers from a problem shared with Erlang.

If you do not have experience to grok the OTP way of doing things you'll likely create worse software than if you used something else, or you'll take twice as long. OTOH, if you do grok how to design things using OTP, then the software you create has a decent chance of being fast and fault tolerant. Erlang in particular is awesome, but I've seen people have trouble finding Erlang devs to hire.
