$LANG is a Rust killer

A few years ago everyone was trying to kill Rails. Now apparently everyone wants to kill Rust. What do you think it would take to dethrone this nigh-invincible language that the entire industry has been using for years and that people are getting hired to write code in? Personally I am waiting for a language called WD-40.

Symta:
X = "['Hello'] ['World']!"

Rust:
let x = ~"Hello" + @" " + &"World" + "!";
