Anything that can be written in Rust will be written in Rust.
I'm using Rust as a placeholder for a language with excellent performance and safety characteristics. It may not be a good thing, but there's no way around it.
If we expand the placeholder, I think "Anything that can be rewritten in a language with excellent performance and safety characteristics will be rewritten in a language with excellent performance and safety characteristics" is a desirable state of affairs.
