Rust is not at all a high-level language in any sense and will not replace the places Kotlin, Go, TypeScript etc occupy. If I wanted to write a super-fast server with some time constraints, I would choose Go without thinking twice. Go is fast enough. Rust is only needed when you need things to be super-duper fast and memory efficient. Those two criterias are the only reasons to use Rust.
