A recruitment post published earlier on LinkedIn by Microsoft Distinguished Engineer Galen Hunt sparked intense discussion across the industry. In the post, Hunt spoke of an ambition to eliminate all C and C++ code from Microsoft’s codebase by 2030, replacing it entirely with the Rust programming language.
The vision he outlined—one engineer, one month, one million lines of code—clearly cannot be achieved through manual coding alone. It implicitly points to large-scale, AI-assisted code generation. In operating systems such as Windows 11, the majority of system-level APIs and even the kernel itself are written in C, while many applications rely on C++. Microsoft has indeed been experimenting with rewriting certain kernel components in Rust, with the primary goal of strengthening kernel security.
Rust has drawn increasing attention for its security properties, largely because code written in C and C++—by companies such as Microsoft and Google—has long been plagued by memory leaks and related flaws that often translate into serious security vulnerabilities. Both companies see Rust as a potential remedy for long-standing memory safety issues.
Microsoft has since clarified, however, that Windows 11 and future versions of the operating system will not be rebuilt using Rust and AI-driven refactoring, stating that there are currently no such plans. Hunt also amended his original post with a clarification:
“It appears my post generated far more attention than I intended… with a lot of speculative reading between the lines. Just to clarify… Windows is *NOT* being rewritten in Rust with AI. My team’s project is a research project. We are building tech to make migration from language to language possible. The intent of my post was to find like-minded engineers to join us on the next stage of this multi-year endeavor—not to set a new strategy for Windows 11+ or to imply that Rust is an endpoint.”
Professionals in the field are not opposed to Microsoft using Rust to refactor Windows or other products. The real concern lies with AI-generated code at scale: extensive, algorithm-driven modifications to critical codebases may introduce new classes of risk.
Microsoft, for its part, has been highly proactive in embracing AI-assisted development. CEO Satya Nadella has previously stated that roughly 30% of Microsoft’s code is already generated by AI—a figure he expects to continue rising. The company’s Chief Technology Officer has gone even further, predicting that by 2030 as much as 95% of code could be AI-generated—not just at Microsoft, but across the industry as a whole.
