FWIW I think Elixir holds a lot of promise for the future. Projects like https://github.com/dynamo/dynamo look really cool. Of course, it's new, and alpha. But maybe we could all give it a try?
Elixir adds some nice metaprogramming features, and I love that it exists. Erlang is used for a lot of Important Things in production, and its value to many developers is stability and fault tolerance. Erlang moves slow. It's nice to see a sister language that can more rapidly develop new language features (maybe some of the goods ones will get added to Erlang (:
Joe Arms post about Elixir is pretty interesting [1]

Node is web-browser style javascript programming, detached from the browser GUI and given the ability to accept inbound connections. Along with this has come a whole slew of fun wheel-reinvention around frameworks and templating engines.
If something indeed is going to take that long, perhaps you shouldn't be making the user wait on it either. Queue that shit.
I have have written a few web apps in Go as well spending most of my time writing things like high performance proxies, CDNs and databases in Go, and IMHO Go is a "more least worst" way to write highly concurrent code compared to node.
