Microsoft CEO Satya Nadella has issued a warning to companies using AI, arguing that they are effectively paying for intelligence twice: once with money for token usage, and again with the proprietary knowledge they must reveal to make the AI useful. In a blog post, Nadella expressed concern that as enterprises feed their sensitive business information into AI models from labs like OpenAI and Anthropic, those labs gain access to knowledge that could allow them to become competitors to their own customers. He warns that models learn from user 'exhaust,' including prompts, tool usage, and corrections, which distills institutional know-how that a competitor could never buy. Nadella argues that if AI companies can freely scrape the internet to train their models, it is only fair that enterprises be allowed to 'distill' those models in return. He finds it hypocritical for model makers to impose restrictive terms on distillation while benefiting from fair use of public data. His proposed solution is for companies to retain ownership of their data, including prompts and feedback, and to build their own proprietary learning environments on the cloud, a suggestion that aligns with Microsoft's business interests as a major cloud provider.
