An essay from the semiconductor research firm SemiAnalysis argues that AI is generating an industrial-revolution-scale transformation, resulting in “dark output” existing national accounts are structurally incapable of capturing.These arguments, while differing in origin and intent, share a common diagnostic error. They treat the problem as one of GDP when the underlying issue lies in the construction of price indices. This distinction matters because the appropriate remedy depends on the problem being solved. Attempting to fix measurement by expanding or redefining GDP is not only unnecessary, it is counterproductive.
