How did computers go from following instructions to chatting with you? A chatbot on your phone makes that leap feel sudden-but it's only the latest chapter. People long imagined machines doing tasks we call intelligent. In 1956, researchers at Dartmouth introduced the term artificial intelligence, or AI: a broad name for machines doing such tasks. Early systems relied on rules people wrote by hand. Tell the machine what to do for each situation, and it followed those instructions. The big shift wasn't machines becoming human. It was moving from hand-written rules to learning patterns from examples. That approach is machine learning: systems find patterns in data. With more data and computing power, these methods helped make today's generative AI, which creates things like text from patterns learned during training. So chatbots aren't where AI began. They went from written instructions to learning from data-and generating replies.
