I am growing closer to being convinced that Rust is here to stay and will actually become the main systems programming language of the next few decades.
I think there's a couple of compatible perspectives that are both correct but often framed as mutually exclusive:
1. Rust will become the main language for new projects
2. There will still be an enormous amount of C that will be maintained for many decades and the majority of "lines of (systems) code" will be C rather than Rust for decades
