The "most trusted code on Earth" is being rewritten in Rust.

Ubuntu 26.04 ships uutils, Rust reimplementations of ls/cp/mv/cat and dozens more, ~88% GNU-coreutils compatible with a GNU fallback, as the default. AWS is funding a memory-safe Rust rewrite of sudo/su. (Fireship) The counterpoint already circulating: a vulnerability was found in the Rust-based sudo, which is a useful reminder that memory safety closes one class of bug, not all of them. Still, the foundational layer of the OS you deploy on is quietly changing languages, and the compatibility is close enough that most workloads won't notice.
