Just by way of example: pay attention to how Niko Matsakis answers the first question ("what is systems programming") on this panel with Bjarne and Alexandrescu and Rob Pike:
(It's hard for me to disagree with any of them, except maybe that I don't at all agree with Alexandescu's argument that systems programming is defined in part by being able to forge pointers from integers --- something, of course, that you can do in both Go and Rust [unfortunately]).
