*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.
If it’s doing “so much damage” - let them crash and burn. That’s all the vinegar you need.
It’s different when it’s people coming and fucking up your project and breaking your rules - then they deserve to be dealt with robustly. But if all they’re doing is fucking up their own product then being a wretched little gossip doesn’t help anyone.
By that logic, we would not need regulation for financial institutions because “the free market will sort it out”.
Except that capitalism or the free market does not care about people. Only people, we ourselves, care about people. We need rules shielding off harm like the guests of a hotel need a fire safety system.
You should enter for long jump with those leaps
But they are fucking up other people’s projects. Badly enough that some are ending paid bug hunting programs or just eating so much of maintainers time looking through bogus bug reports that development stalls.
Some of the ways in which bun came fucking up zig’s ecosystem can be found in Andrew’s own blog post.
