Fireship·medium signal

Fireship's 5:52 breakdown of Bun's 11-day Zig-to-Rust refactor pulled ~397K views within 24 hours of its July 15 upload, framing it as 'the most controversial rewrite in history' and explicitly noting 'not everybody is celebrating.' The velocity matters as much as the content: it marks the point where an agentic migration story broke out of engineering circles into mass developer awareness, and it is the delivery vehicle carrying Andrew Kelley's 'unreviewed slop' critique to a general audience.
