*The Rustification of Bun#

Rewriting 500,000 lines of Zig into another language would be a gargantuan undertaking if done by hand. “A rewrite in another language would take a small team of engineers a full year. It would mean freezing bugfixes, security fixes or feature development for that time,” Sumner wrote.

Instead, Sumner went with Claude. He spun up about 50 dynamic Claude Code workflows, reaching a peak of about 1,300 lines of code per minute and generating over a million lines of Rust code. The job took 11 days and cost about $165,000 at API pricing. Claude Fable did most of the heavy lifting.

My modest career in software development has shown me that the real value of a developer isn't how much code they can write, it's how well they understand the existing code base. LLMs can't understand because that requires memory larger than an LLM's context window, by orders of magnitude.
