Last year, according to Stackoverflow polls, Elixir was the second most loved language, just under Rust. There is a reason why people who knows it, loves it.

Elixir’s runtime, unlike many others, uses preemptive lightweight processes. Unlike async-only systems, a runaway process won’t block out other processes. That’s just the start of the kind of advantages in writing with Elixir/Erlang/OTP

It’s been battle tested for years. I think many of the hype cycles for distributed systems reexplore or reinvent what Erlang and Elixir has to offer.
