When things get serious, I think you'll discover that Go provides far less reliability, and is far more complex. (What's simpler than "it's already handled for you with OTP and battled tested for 2 decades"? That's a lot more simple than "you can't do it in this language and you'll end up with a poorly implemented half version of OTP in Go."

Of course for toy or small services, go is fine. Erlang certainly could use the "build a binary run it anywhere" distribution model of Go tool.

But reading all these pro-go articles, it strikes me that none of them seem to be written by people who really understand concurrency.

Believe me, I wish Go was written by people who had understood erlang. There's a lot to like about it and it has momentum.
