Why would someone use Rust over Java/Kotlin/Scala/C#/F#? Macros would be a small improvement, but at the price of reflection (JVM has Clojure for this). If I was using one of those languages, I don't really think the performance gain from moving to Rust would outweigh the added mental overhead, cost of learning new libraries, or developer scarcity. I would use Rust in place of C++ or C in a heartbeat (and I would probably pick it over Go until they have generics), but I wouldn't use it in place of those other languages for the same reason I wouldn't use C++ in place of them. They're already managed, and I wouldn't have used them in the first place if I needed Rust's performance.
