If you're serious about using the type system to encode business logic, improve resiliency, and reduce runtime errors: scala is really a great choice. Beware "type astronauts", FP purism, etc. and you'll be able to go very fast. You get access to the whole JVM ecosystem. Rust is great but more clunky. I'm under the impression F# is a viable alternative.
