I like Rust, however as usual the article fails short of mentioning Ada, and GC languages that share the same resource management capabilities as C++, alongside their GC.
I just made the point, because from security point of view, we all have to gain no matter what safe systems programming languages get adopted.
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.
