Nadella warns AI buyers pay twice: in money and proprietary knowledge

Microsoft CEO Satya Nadella has introduced a concept he calls the 'Reverse Information Paradox,' drawing on Nobel economist Kenneth Arrow's original theory. In an essay, Nadella argues that enterprises purchasing AI solutions effectively pay a dual cost — financial and intellectual. As companies feed their proprietary data and expertise into AI models, the vendor's systems grow smarter while the buying firm gains comparatively little knowledge in return. Nadella's warning highlights a structural imbalance in how AI value is currently distributed between sellers and enterprise customers.
