Forget chatbot training. AI's next big data grab is about learning how humans work.

AI development is shifting away from chatbot training on internet text toward using reinforcement learning environments (RL) to teach agents how humans work. Tech companies are creating realistic digital workplaces where AI can practice tasks like coding and running business software. Major players include Meta, which tracks employee activity, and Google, which is considering a large investment in Mechanize, a startup that builds virtual training environments for AI agents.
