I have to say, I'm really exhausted with the way every single C/C++/Go discussion on HN ends up having someone chime in to say, "Why not just use ~Rust~?". I'm a huge fan of Rust, as I'm sure many of us are, but it isn't some cure-all. It can't just be dropped into any arbitrary use-case where performance happens to be somewhere on the radar, and magically surpass all other options.
