It's the only production-ready language that is both memory safe and has zero-cost abstractions (i.e. for any C code you have Rust code that compiles to equivalent assembly, and using more abstractions in Rust does not make the assembly less efficient unless the abstraction can't be implemented otherwise). Also as long as you accept not having dependent types (at least for the short and mid-term) and several currently unimplemented features, Rust is the optimal way a programming language can be designed other than assorted minor warts.
