This document provides a timeline summary of important events and developments in the history of artificial intelligence from 1950 to 2023. Some of the key milestones include Alan Turing introducing the idea of artificial intelligence in 1950, the development of the first artificial neural network and self-learning program in the 1950s, the coining of the term "artificial intelligence" in 1956, and the creation of influential early programs like Eliza and Shakey in the 1960s-1970s. Major advances in deep learning, neural networks, and general AI capabilities are shown in the 2000s-2020s with systems like Deep Blue, AlphaGo, GPT-3, DALL-E, and AlphaFold demonstrating superhuman performance.
