Microsoft CEO Satya Nadella described the "Reverse Information Paradox," warning that in the AI age, firms risk giving away proprietary knowledge when using AI services. Nadella stated, "You essentially pay for intelligence twice, once with money, and again with something even more valuable: the proprietary knowledge you must reveal to make that intelligence useful." He noted that as clients improve AI models through use, the work data passes to the AI service provider's server, where the newly acquired knowledge becomes fully owned by the AI firm, which can then build superior models and sell them. The article highlighted that news publishers have sued gen AI firms for alleged intellectual property theft and unauthorised data scraping, and large companies using services like OpenAI's ChatGPT-powered Copilot, Anthropic's Claude, and Google Gemini have raised concerns over proprietary knowledge protection. Nadella's comments were posted on the X platform.
