Memory safety without garbage collection was once considered impossible. Rust has proved the skeptics wrong, and major tech companies are taking notice.

The Linux kernel, Android, and the Windows kernel have all started incorporating Rust. This isn't a trend — it's a fundamental shift in how critical infrastructure is built.
