To be fair. I'd be fine lumping Golang in this camp as well.

Theyre all different languages and ecosystems.

But in terms of what use cases they fill? Theyre more similar that not.

In otherwords if I'm evaluating Java for a use case, in many situations, I'd also be evaluating C# and/or Golang along side it.

Where as it would be less common for me to compare Java against Python, Javascript, Elixir, Erlang, Rust etc..
