Absolutely. Most programs should be written in a safe language, but that doesn’t mean Rust. Most programs should be written in a garbage–collected language like Javascript or Python or Lisp precisely because those languages make developers faster and more efficient. Rust is only appropriate for programs that are too expensive to run when they are written in a garbage–collected language. That means operating systems, because small inefficiencies there will add costs for billions of people. It means big server–side services, where small inefficiencies cost you millions in compute time or ram usage or whatever. Even if you think you’re going to hit that scale one day, writing your prototype in a garbage–collected language can net you a huge advantage in time saved. You can rewrite it in Rust later, after you know exactly what features will be needed and exactly what they cost to run, and exactly how much you’ll save by rewriting it in Rust.
