Rust is hard, from a systems programming perspective, not because of anything about the problem domain but because Rust has an unusually narrow perspective of what systems programming entails. And it is unforgiving for software that has requirements outside that perspective, which happens more often than I think some Rust proponents allow. Modern systems software architectures are thread-per-core, involve a lot of DMA, etc for performance reasons. That is language agnostic, though most is written in C++ because it is amenable to it. This obviates a lot of the safety features Rust obsesses over. It often feels like the Rust community hasn't acknowledged that this is how systems software actually works these days, or the deficiencies of the language in supporting these software architectures.
