ChatGPT didn't come out of nowhere. It's the result of 60 years of dead ends, one accidental breakthrough, and three completely separate technologies all maturing at exactly the same moment. Before the Revolution: Chatbots That Didn't Learn AI is older than most people realize. But early AI looked nothing like what we have today. ELIZA (1966) was the first chatbot. It simulated conversation using pattern matching — if you typed "I feel sad," it replied "Why do you feel sad?" It didn't learn anything. It followed hand-written rules. Impressive for 1966. Useless for anything complex. RNNs emerged in the 1990s as the dominant approach for language processing. LSTMs (Long Short-Term Memory networks), invented by Hochreiter & Schmidhuber in 1997, improved on RNNs specifically to address memory limitations — but both shared the same fundamental design: reading text sequentially, word by word, like looking through a keyhole. By the time either reached the end of a long sentence, the begin
