I had a brief look at Erlang in my spare time. Time passed, and I would have returned to it at some point, but then Elixir appeared on the radar, and it appears almost as a refreshed, improved Erlang, an Erlang 2.0. Well, why would I learn yesteryear's implementation instead of a modern implementation? So, I looked at Elixir, and now would need an unlikely compelling reason to look back in Erlang's direction with any serious effort. When people talk about Erlang, they talk about telephone switches and data stores - I'm never going to be hired to build either, how many are? Elixir being used for more modest feats of engineering makes it sound more appealing and accessible to the mortal majority, hence building momentum. That said, I've just looked at the roles advertised at a large London tech fair - two Golang, zero Elixir, zero Erlang, numerous .Net and Java, countless Javascript. Long way to go for new languages, and London feels excruciatingly risk-averse.
