Rust is missing garbage collection (which is by design, but IMO manual memory management is the wrong hair shirt to wear), and maturity.
What I want is OCaml without people complaining about concurrency (which I suspect is mostly FUD - how many people who choose go "for performance" actually profile their programs? I get the sense there is this group of people who think any high-level language is inherently as slow as Python). Or Haskell without laziness (maybe Idris will eventually become this?), and perhaps with a lower-friction approach to I/O. Or Scala with native compilation (again I think complaints about this are probably mostly FUD, but if nothing else the JVM startup latency is real). Or any of these three getting the hype that Go gets, tbh.
So, uh, what are you actually after? Just use Scala if that's what you want. If you can't be bothered to manage memory in rust, then it seems hard to believe that native compilation makes a difference for you.
Is it all just about the hype? Write code, ship products.
As I said, the JVM startup latency is a real issue. I'd like to be able to write little command-line utilities in Scala (or a Scala-like language) and not have to wait a second when I run them.
But yeah, I'm writing and shipping in Scala, and life is good, I shouldn't care about people hyping what I don't like.
