Practical as there is already a lot of software written (or rewritten) to Rust. Sometimes for safety, sometimes - purely for performance. I don't claim it is an easy language or a universal solution. Compare and contrast with pure languages that are less versatile. Sure, Haskell has its practical uses. From a popular example - Pandoc. Yet, I know many programmers who have been preaching it is the best language but could not write a performant program that solves a given task that does not focus on algorithmics. By contrast, PHP or early JavaScript were not pure by any sane standard. Yet, they conquered the web. (Fortunately, ES6 and TypeScript made the JavaScript environment much saner.)
