Anything specific you liked about Elixir more than Go?

  As someone who writes both, it's even difficult to compare these as they are apples and oranges. Elixir (due to Erlang base) is great for long-running or distributed services and includes tooling to, for example, easily introspect the state/memory usage of your services down to a single mutable data structure, to heal from failures, and to hot-swap upgrade/code while the server is still running, and to perform node-to-node RPC. Go would be a replacement for something that was previously written in C/C++, that may need concurrency, and that should compile to native code. You get very fine-grained control of everything from network to file operations and excellent concurrency constructs. A web crawler, a device driver, or writing an Nginx/HAProxy-type daemon, all may be great example use cases. One could write their next social network/app backend using Go (just as one could do it in C), but it would probably take more work than just using a higher-level language.

    Go is much more suited for web apps than any driver or real time performance application; although, I will agree that using Go for command-line tools is great. I haven't used Elixir but as somebody who uses Go, I highly recommend not replacing C/C++ with it unless it isn't performance critical. PS: Go's memory usage is pretty up there some times, another reason you should probably stick with C/C++ in the context mentioned above.

  I'm the wrong person to answer that, perhaps, but with OTP you get a task broker / monitor for free. With Go we would be back to piecing together a system using other tools such as AMPQ or similar. It also isn't as easy to write it for high-concurrency monitored tasks. But I have little experience with Go, so correct me if I am wrong.
