C programmers had to learn plenty of new skills over the decades, but the core language knowledge remained transferable in a way that's rare. Someone who mastered pointers and memory management for Unix in 1980 could understand Linux kernel code decades later. The same C skills applied whether writing MS-DOS apps, embedded firmware, or early CGI web code. It's the consistency across wildly different computing eras that made C unique. No other mainstream language has spanned from mainframes to microcontrollers to web servers while keeping its fundamental approach intact. That's the kind of cross-domain stability that makes Rust worth watching.
