You can't run Java either as it's compiled to bytecode, yet when someone says "we made Java 10x faster" you wouldn't assume that just the compilation got faster, right? When people market Rust projects as blazingly fast nobody assumes it's about compilation, in part because a blazingly fast Rust compiler would be a miracle. Outside of this comment section people have always been using a programming language name for this because everyone knows what they mean.

It would be possible that MS wrote a TypeScript compiler that emits native binaries and that made the language 10x faster, why not?
