Kroah‑Hartman consistently framed language choices in terms of reviewer workload rather than developer convenience. Linux has "over 5,000 developers" but "about 150 core maintainers that review the majority of the code," a skew that drives his priorities. "We optimize for reviewers. We don't optimize for developers because we have a lot of developers," he said, suggesting Rust's ability to enforce locking and lifetime rules at build time means reviewers can spend their limited bandwidth on logic rather than bookkeeping: "If it builds as a reviewer, I know it's OK. I can look at the logic."

That's a great point. Living open source code must be readable and maintainable. Rust is an excellent match for that.

And with AI joining in with developers the workload on reviewers has increased

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
