I don't understand your argument. You will have problems finding Erlang devs, especially if you are not located in the SV. You will find it difficult and/or prohibitively expensive to even get Erlang training for your devs. And yes, Erlang is pretty new in terms of having made the jump from total obscurity to near total obscurity less than ten years ago.

If you are lucky to have a team with the skills by any means go for it. But introducing Erlang to an average project with average requirements, staffed by average developers is a recipe for disaster.

No I didn't. I implemented the core of the backed at my last job in Erlang. Training newbies and hiring was not difficult. I interviewed the candidates coming in when I needed to pass the baton too.

And no, Erlang is not new. It is stable. The interface changes once a decade, and usually for the better. Stop making these wildly unsubstantiated claims based on little to no evidence. Even if you had a direct experience, it's certainly contrary to mine, and definitely not enough to warrant your sweeping assumptions.
