It's kind of all over the place. The initial point is simply that Go or C# or Java in their normal form aren't "system programming" suitable (which generally means low-level kernels and system services and projects having similar needs. Notepad on Windows isn't system programming), and it's unrealistic for Go to be ranked highly on such a list, much less before Rust which is purpose built for this task. Could someone use them for system programming? Sure they could. It would be the wrong tool but people makes loads of bad decisions. The point about Linux and other operating system choices wasn't a rule, it was an observation that the rhetoric often plied on developer boards -- usually where developers want everything to be a nail to their skillset hammer -- has little correlation with the world. Nowhere did I exclude Ada or any other compiled, non-GCd (which Ada never uses when used for anything of any criticality) languages. Anything can make just as good of native code.
