Writing Faster Than We Can Read

This week's thread is simple: machines now write code faster than humans can read it. Anthropic's CI absorbed a 25x job increase in six months, pushing the bottleneck from writing code to PR review; a behavioral guide insists agents carry no responsibility and PRs should stay under 600 lines. Along the way, a $38B fund shows how it evaluates and governs frontier models, and a new release shifts the cost curve. But we are not here only to talk about speed. Bob Nystrom reminds us that overlong names are a symptom and that meaning cannot be outsourced; ACID and "make invalid states unrepresentable" both argue that the scarce resource was never output but constraints and structure. When generation becomes cheap, the crafts of design, review and governance get expensive. That is the sentence this issue points to.
