I work at Meta and I use tools written in bash, C, Java, Go, TypeScript, Kotlin and Dart daily. I've definitely noticed that some C++ tools are moving to Rust. I would have preferred to see D in its place, but it is what it is.
Personally I'm not a fan of Rust, but it is interesting to see how the language is growing as it hits mainstream. Lots of similarities with Go back when it was cool and hip.
