The great programming transformation: How AI and Rust are quietly dethroning C in Linux

Microsoft is focusing on AI development more than Linux, with 20% to 30% of its code now generated by AI. Galen Hunt aims to eliminate C and C++ from Microsoft's codebase by 2030, envisioning a transition to Rust, although not a complete rewrite of Windows. Microsoft is integrating Rust into security-critical areas, while Linux is also adopting Rust through initiatives like Rust-for-Linux and plans to write its apt package manager in Rust. Both companies are using AI to streamline development, with Microsoft allowing AI to autonomously handle coding issues, while Linux maintains human oversight in decision-making. Rust is seen as a safer alternative to C due to its memory-safe design, despite some challenges, including identified security bugs.

Microsoft engineer says Windows isn’t being rewritten to Rust with AI

Galen Hunt, a Distinguished Engineer at Microsoft, has proposed a plan to phase out all C and C++ code within the company, emphasizing that this initiative is focused on developing technologies for smoother transitions between programming languages rather than a complete rewrite of Windows in Rust. Microsoft aims to eliminate technical debt and address memory-related vulnerabilities, which account for about 70 percent of vulnerabilities in its products, by adopting Rust, a language known for its memory safety features. The company is leveraging advanced tooling and AI to facilitate the transition, and Hunt is seeking a Principal Software Engineer with Rust expertise to support these efforts. Microsoft’s commitment to Rust reflects a broader trend of increasing adoption of the language, with significant growth in enterprise settings. Major tech companies are also integrating Rust into their infrastructure, highlighting its importance for critical systems.

Microsoft engineer says Windows isn’t being rewritten to Rust with AI

Galen Hunt, a Distinguished Engineer at Microsoft, has proposed to eliminate all C and C++ code within the company, focusing on transitioning to Rust. This initiative aims to address technical debt and improve memory safety, as C and C++ are responsible for approximately 70% of vulnerabilities in Microsoft products. Microsoft plans to leverage AI and modern tooling to facilitate this transition, which includes rewriting portions of the Windows kernel in Rust. Hunt is seeking a Principal Software Engineer with Rust expertise to support this effort. The adoption of Rust is growing globally, with a reported 2.3 million developers using it, and major tech companies are increasingly integrating it into their infrastructure.
