I rarely use Rust for the performance or memory safety - it's a nice perk that allows for data structures and algorithms I wouldn't otherwise use but it's not the main reason I reach for it. I use Rust for its type system including traits, phantom marker types, affine types, sum types, exhaustive pattern matching, and so on. Once you get used to traits and composition over inheritance, it allows writing very reusable code that enforces a significant fraction of logic at the compiler level and scales much better with code and team size (modulo dependency hell, which I think is language agnostic but a work in progress in Rust). Rust's model of wrapping unsafe code in safe types also makes working with the world of C/C++ libraries much more pleasant once you get the hang of FFI. Plenty of other languages have these features but not quite in the right combination or their communities are too small and they haven't caught on yet. Rust is, in my opinion, at an organizational and technical sweet spot for large projects.
