I had the same reflexion about 2 years ago. Realistically, pretty much any program written in NodeJS can be ported to Go and vice versa. But not every Rust program can be ported to NodeJS/Go. It opens up a new class of software that is not typically available to NodeJS/Go developers (e.g. systems programming, embedded, writing libraries for other languages, etc.).

So I went with Rust and am very happy with the decision. Despite being a systems programming language, it feels surprisingly like a high-level language and I now default to programming stuff in Rust unless there's a strong reason to use NodeJS.

PS: That said, an often understated benefit of Go is that the community and job opportunities are massive in comparison to Rust (for now, at least).
