Microsoft is planning to replace C and C++ with Rust across its codebases by 2030, as stated by engineer Galen Hunt. The company aims to eliminate every line of C and C++ using artificial intelligence and advanced algorithms, targeting a goal of “1 engineer, 1 month, 1 million lines of code.” Microsoft has developed a code processing infrastructure to support this initiative, which is already operational for various code understanding challenges. In 2023, Microsoft began rewriting parts of the Windows Kernel using Rust due to vulnerabilities associated with C and C++. The new role advertised by Hunt is part of the Future of Scalable Software Engineering group within Microsoft CoreAI, indicating a significant investment in modernizing Microsoft's code for enhanced security and efficiency.
