Microsoft wants to replace its entire C and C++ codebase, perhaps by 2030

Microsoft is pursuing a research initiative to build AI- and algorithm-assisted tooling to translate large C/C++ codebases to Rust in pursuit of improved memory safety, with a stated long-term goal of significantly reducing legacy code; the effort includes a Principal Software Engineer role in Redmond. The company emphasizes this is not a plan to rewrite Windows in Rust, but rather to develop scalable migration capabilities, aligning with broader industry and government pushes toward memory-safe languages.
