When programs grows in complexity, Rust shines. Extra guarantees are very handy when code refactored. It hard to compile Rust code, but when it compiled, it usually works (or quickly points out to problem).

I actually use it in parallel with C/C++ legacy code, and I just trying to avoid C/C++ as much as I can, because I newer saw segfault in safe Rust code so far.

Especially when you're just reading some pre-written code. I've rarely (never?) seen any complaints about how reading Rust is hard ... but lots which say that writing the code itself can be frustrating
