I would offer a counterpoint -- Rust's guarantees and strong typing offer a different kind of productivity to an intermediate or experienced user. One where a compiled program is much more likely to be "correct" than in any other mainstream-esque language I've used. The properties which combine to create this effect make refactoring much less scary, allow easier navigation in large codebases (IMO), and allow for other valuable properties for productivity.
