The author translates the paper's economic production functions into Amdahl's Law terms, finding that the global parallelizable fraction (P) stays stubbornly around 35% across all three generations of AI tools. This means the hard ceiling for total shipping improvement is roughly 53%, because the remaining 65% of developer time — planning, meetings, alignment, and reasoning — cannot be parallelized by current AI. The analysis explains why macroeconomic and team-level productivity gains from AI coding tools remain modest despite impressive task-level speedups. ## Full article daily.dev links to this article rather than hosting it.
