ELIZA: The First Chatbot
Joseph Weizenbaum created ELIZA, a program that simulated a Rogerian psychotherapist using simple pattern matching. Despite being purely rule-based with no understanding, users became emotionally attached to it and insisted it truly understood them — a phenomenon Weizenbaum found deeply disturbing.

ChatGPT: AI Goes Mainstream
OpenAI released ChatGPT, a conversational AI based on GPT-3.5 fine-tuned with RLHF (Reinforcement Learning from Human Feedback). It reached 1 million users in 5 days and 100 million in 2 months — the fastest-growing consumer application in history. People used it to write emails, debug code, brainstorm ideas, and a thousand other tasks.
