The Death of the Code Review: What the Data Actually Says (Laurie Voss (Arize AI))

talk · Story page

A wide chute pours a thick column of paper sheets into a funnel. A seated figure at the funnel's narrow waist holds a magnifying glass over one sheet. A thin trickle of sheets falls out below into a small tray.

Developers using autonomous agents wrote 741% more code and shipped 30% more software. Voss's case is that review is the bottleneck: reviewer effectiveness collapses past about 400 lines, while agents open 10,000-line PRs.

In plain words

  • Laurie Voss examined why artificial intelligence helps write software faster than people can check it.
  • People become much less effective at finding mistakes when a change exceeds about 400 lines of computer instructions.
  • Artificial intelligence now proposes changes running to 10,000 lines, creating more work than reviewers can reliably handle.
  • Voss argues that checking work limits how much software teams can release, even when writing gets much faster.
