I think you're seeing Rust used more and more frequently for backend services, like at Dropbox and NPM. Some of those are high-performance, "C++ish" services, as I think Dropbox's was. But a lot of others might plausibly have been written in Java, C#, or Go. In NPM's case, they rewrote a service in Rust that was previously running on NodeJS.
