> You could re-implement erlang in C++, but then you'd end up with erlang again. Why not just use erlang in the first place?

Because rewriting or shimming the 10MM lines of code in the libraries one depends on outweighs this one particular benefit of erlang.

Define "real concurrency".

This one particular benefit is not available in any other language, unless you start with a relatively low level language like C and recreate it.

Multi-threading is doable in any number of languages, but the problems inherent with it are why people move to concurrency.

Concurrency needs to be supported in the language itself.

You'd spend 20 years recreating this in C++ vs 2 weeks learning erlang.
