Why software is converging on Rust in the age of AI
For a decade, 'rewrite it in Rust' was a joke, because rewrites took years. In 2026, Ladybird, Bun, Meta's React Compiler and GitHub's Copilot runtime were all ported to Rust with AI agents in weeks, and a solo developer cloned Photoshop. Cheap rewrites explain the timing. The choice of Rust comes down to who reads the code: when agents write faster than anyone can review, the language whose compiler checks the most wins. How far that has spread, from browsers and kernels to creative tools, and where Rust still isn't winning.
