Rust is better suited as universal language than Scala for me as I am writing also music applications, which really hate the garbage collector needed in Java/Scala, things that run on the JVM. I never really needed recursive types, but that's also something limiting on the JVM.

That's the conventional wisdom about GC, but I'm not sure how true it is these days - prototyping a video streaming program in a previous job we were surprised to discover that Haskell performed significantly better than C++ in that role. The JVM GC is quite tuneable and if you're willing to sacrifice throughput for latency you can get it quite low.

(Rust has a lot of good points but I won't be interested until it gets HKT).

What do you mean? Recursive types in the sense I'm used to work fine on the JVM; there is even e.g. a recursion-schemes like library for Scala (matryoshka).
