Keynote: Unsung Heroes of the BEAM - Code BEAM SF 2018

I personally like Erlang because of the short implementation times, I love how easy it is to make concurrent distributed systems and implement communication protocols. It is less verbose than other languages and so less prone to errors. With its stable API, it is also low maintenance and used to resolve challenging problems. The fact that it is in high demand and you often get to work remotely, are a bonus too.
