"advanced and useful type system, expressive syntax out of box, and reasonable macro support" Those things are nice, but don't have anything to do really with the question here. Rust is designed to be 'close to the metal' and due to that fact, and a few other things - it's an 'advanced' programming language. Javascript, Python (and PHP at least today but that's changing) will have 10x a greater user base than Rust ever will. In the Enterprise, Java and C# are going nowhere. Rust will be the domain of only a specific set of software developers, and they will share that space with C++.
