I wouldn't want to mention any language I don't have experience with for the risk of mis-speaking. I also tried to minimize talking about any specific language where I could.

It doesn't need to be Rust vs the others, in what concerns improving the current state of IT security.
For example, Nvidia is now adopting Ada/SPARK for security critical firmware.
