Since when is Rust a systems programming language? On their website it is defined as "general-purpose programming language".

>Approaching every problem as a systems programming problem is a massive waste of resources and intellect.

If someone took their time and decided to use Rust maybe their first couple projects won't be as efficient, but they will learn the language and how to use it in the best ways, they will contribute to the ecosystem, etc. Again, I'm looking at the big picture and not specific project case.
