Most applications should probably just be written in a garbage collected language, but Rust and C and C++ are mainly there to support use cases where running a garbage collector isn't appropriate. (I.e. you're trying to get your code to run as fast as possible, and don't mind doing some extra work.) Maybe there's a reasonable case that Rust has developed to the point where an experienced Rust user is just as productive as an experienced Java or C# user even when it comes to tasks that aren't performance critical. For my part I think I'd rather use Haskell than Rust for tasks where GC overhead isn't a deal-breaker.
