If it serves the purpose, it is worth the price of changing the way one thinks. You do realise than functional, imperative and procedural programming all coexist in this world. But using functional programming with trees for example makes your job way easier. Except you'll have to change your perspective on programming. It's the same thing with memory safety. If Rust is going to give you a guarantee about the memory safety, then changing your mindset is probably worth. I still consider myself a beginner/novice though, so this is just my opinion.
