Agentic coding creates systemic defect accumulation that outpaces human review capacity¶
Insight: Mario Zechner (via Simon Willison) argues that orchestrated AI agents eliminate the natural bottleneck of individual developer output, generating thousands of lines where a human produces manageable amounts. Small defects compound rapidly into systemic problems because developers "have zero idea what's going on" after delegating to agents. The proposed remedy is intentional slowdown: setting daily code limits aligned with review capacity and handwriting critical architectural decisions.
Detail: Willison agrees that coding speed is no longer the bottleneck but is skeptical about handwriting code specifically as the solution. This corroborates the broader pattern that comprehension debt and verification — not generation — are the real constraints in agentic workflows. Zechner's framing adds urgency: unlike the gradual 80% problem, agent-orchestrated accumulation creates compounding systemic failures that are invisible until catastrophic.
