I don't think your last point is entirely accurate. I've programmed in Python since the mid-90s and Ruby since 2005, and developers in both camps want concurrency. I think this is why Elixir has really taken off amongst Ruby developers. It is similar enough to Ruby that they don't feel lost, but it makes concurrency extremely easy; a lot more so than Go does, in my opinion.

My reasons for dismissing Go are mainly due to the way it handles memory. Concurrency is handled in Go using shared memory, as opposed to Elixir's private memory model, and Go's threads are not guaranteed to politely take turns the way Elixir's are. I also think Go's packaging system is quite flawed.

I also dislike Go's syntax, but that is just a matter of personal taste.
