Rust vs C: Memory Safety Is Ending C's 50-Year Reign #Shorts

Rust vs C in systems programming — and the gap is closing faster than most engineers expected.

Seventy percent of critical CVEs in C and C++ codebases trace back to memory bugs. Rust eliminates that entire class of errors at compile time through its borrow checker, while matching C within two to five percent on raw performance. That trade-off is getting harder to ignore.

Microsoft, Google, and the NSA have publicly told developers to stop writing new system-level code in C. The Linux kernel now accepts Rust. These are not opinions — they are institutional decisions backed by vulnerability data.

C still owns legacy embedded systems and bare-metal microcontrollers where decades-old toolchains make any migration a full rewrite. But for new systems projects, the question is no longer capability — it is how long a fifty-year head start in tooling and talent can hold.

In this Short:
• Why 70% of critical CVEs point back to C memory bugs
• How Rust's borrow checker stops errors at compile time
• Rust entering the Linux kernel at version 6.1
• Performance comparison: Rust vs C benchmarks
• Why Microsoft, Google, and the NSA moved away from C
• The real cost of starting a new project in C today
