Depends of your goal. For low level stuff : Rust. For scripting systems that are simple to write, Python or Ruby are quite great. If you want some OO but better, Scala or OCaml are around for a long time and deal with concurrency better. If you really want concurrency and parallelism, Elixir/Erlang are there and Pony is growing slowly. They are all better than Go at what Go aim for, without the hurtful decisions. And they are better supported on a wide amount of systems.
