Laurie Voss: code review is obsolete in the age of AI agents

npm co-founder Laurie Voss argued at AI Engineer World's Fair 2026 that traditional PR review no longer works: developers using autonomous agents wrote 741% more code but shipped only 30% more software. He says review must move up a layer — to systems, rules and evals — rather than reading every diff.

• Agent users wrote 741% more code but shipped only 30% more software
• Humans can't reliably review faster than 450 lines per hour
• Bun passed 99.8% of tests yet shipped 13,044 unsafe blocks
• Automated reviewers were fooled by malicious code 88% of the time vs 35% for humans
