I don't really get the affinity of Go and Ruby. The most similar thing I could say about them both is that they're both not Java. This makes sense from a hiring sense, either your hiring from the large Jvm/.Net pools or you're not.

I suppose both Ruby and Go have less steep learning curves compared to Java/Kotlin/Scala.

I can't wait until Go v2 gets generics then I can use it like other statically-typed compiled, gc'd languages. At the rate of Go language development, Java might get coroutines and value-types before then.

I haven't used Rust but I read the "Rust where the compiler constantly shouts “fuck you”" quote differently. I read it as, where the non-existent Ruby compiler will shout “fuck you” in production.
