This is so true Moving back from a Scala application to Ruby feels like having an arm and a leg chopped off. However if you like safe compiled languages i can only recommend to have a look at Rust. Having a compiler that guarantees code to be free of deadlocks and such at compile time is just incredible. And it is not even that hard to learn compared to Scala. Scala is a really great language. But its open syntax, which ranges from c like imperative with curly braces to points free style can be hard to grasp. Not speaking of obscure compiler messages when a library using a weird dsl is missing some implicits. Rust being more opinionated and having less stuff shoved into it while having all the stuff you need is really great. The borrow checker has like half the rules of the "this" keyword in JavaScript ;)
