For what it's worth, Rust includes a lot of pragmatically useful research stuff that was passed over in Go. In particular, I think Rust's emphasis on immutability is a better decision that will result in faster, lock-free code. (Yes, it counts as locking when you have to pass the one-and-only pointer to a thing over a channel just to read it.) But Rust is a big complicated language. Go is syntactically tiny, and that's an advantage in an number of ways, from speed of compilation to ease of use.
