Should AI Engineers Still Read Code in 2026? The Z/L Continuum — Alex Volkov, ThursdAI
Jul 10, 2026 · 21:35
Alex Volkov examines the debate sparked by Ryan Lopopolo's claim that 'code is free' and Mario Zechner's counter that engineers must 'read every fucking line' of critical code, arguing that the Z/L Continuum is about task-level proof rather than personality. Citing a Ferrous AI survey showing an 861% increase in code deletion per PR and a 242% rise in incidents, he notes Anthropic's recursive self-improvement essay admitting human code review is a new bottleneck. Volkov's routing table prescribes reading every line for authentication, money movement, and irreversible data, while letting agents handle less critical changes. He also introduces loops—cron-like agent systems that self-verify—as the next frontier, quoting Adi Osmani that automated loops don't remove judgment. Volkov concludes that capability drift moves where proof belongs, but every system still requires human judgment.
