Joseph Weizenbaum creates ELIZA, the first conversational agent in history

MIT professor Joseph Weizenbaum published ELIZA—a computer program that could simulate conversation by pattern-matching and keyword-triggered script responses. Its DOCTOR script mimicked a Rogerian psychotherapist so convincingly that Weizenbaum's own secretary asked him to leave the room so she could speak with it privately. This was the first time anyone mistook a machine for a human conversational partner.

"Attention Is All You Need" — the Transformer architecture is born

Eight Google researchers published 'Attention Is All You Need' at NeurIPS 2017, introducing the Transformer architecture. By dispensing with recurrence and convolution entirely and relying solely on self-attention mechanisms, the Transformer achieved state-of-the-art translation results while training significantly faster. The paper has been cited over 250,000 times, and the Transformer became the foundation of every major AI system since—from GPT and BERT to AlphaFold and modern speech models.

OpenAI releases GPT-3, proving that scaling language models unlocks emergent capabilities

In June 2020, OpenAI published GPT-3 (Generative Pre-trained Transformer 3), a 175-billion-parameter language model that demonstrated remarkable few-shot learning—the ability to perform novel tasks from just a handful of examples without fine-tuning. GPT-3 could write essays, generate code, translate languages, and answer questions at a quality that often blurred the line between human and machine output. The paper 'Language Models are Few-Shot Learners' (Brown et al.) validated the scaling hypothesis: larger models trained on more data get qualitatively better, not just incrementally better.
