Yes, and if you want move fast and don't break things you need a higher level language like Go, Java, C#, etc.

I'm pretty fast in Rust but not as fast as Go, mostly because Rust's type system and borrow semantics come with a higher cognitive load.

I find both to be faster than C++. Rust is faster because I have to worry less about blowing my feet off with memory errors. I can't think of anything to recommend C++ now that Rust exists.
