Introduction: The Dream That Became Reality
What if machines could think like humans? This question, once confined to the realm of science fiction, has become the driving force behind one of the most transformative technologies of our time. The journey of Artificial Intelligence (AI) spans over seven decades, filled with brilliant minds, groundbreaking discoveries, and moments that forever changed how we interact with technology.
From the first computer programs that could play checkers to today's sophisticated large language models and neural networks, AI has evolved from a theoretical concept to an integral part of our daily lives. This comprehensive timeline explores the pivotal moments, key figures, and technological breakthroughs that shaped the AI revolution.
The Foundation Era (1950-1960): Where It All Began
1950: The Turing Test – Defining Machine Intelligence
The story begins with Alan Turing, often called the father of computer science. In his groundbreaking paper “Computing Machinery and Intelligence” published in Mind, Turing posed the fundamental question: “Can machines think?” His proposed Turing Test became the gold standard for measuring machine intelligence, challenging a machine to engage in conversations indistinguishable from those of humans.
“I believe that in about fifty years' time it will be possible to programme computers… to make them play the imitation game so well that an average interrogator will not have more than 70 percent chance of making the right identification after five minutes of questioning.” – Alan Turing, 1950
1956: The Birth of AI as a Field
The term “Artificial Intelligence” was officially coined at the Dartmouth Conference, organized by John McCarthy, Marvin Minsky, Nathaniel Rochester, and Claude Shannon. This historic 10-week workshop at Dartmouth College brought together the brightest minds to explore the possibility of creating machines that could simulate human intelligence.
The conference proposal boldly stated: “We propose that a 2-month, 10-man study of artificial intelligence be carried out… The study is to proceed on the basis of the conjecture that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.”
1957: The Perceptron – First Neural Network
Frank Rosenblatt developed the Perceptron at Cornell University, creating the first artificial neural network capable of learning. This single-layer neural network could recognize simple patterns and laid the groundwork for modern deep learning algorithms. The Perceptron represented the first successful attempt at creating a learning machine.
The Optimistic Years (1960-1970): Early Breakthroughs
1961: First Industrial Robot
Unimate, the first industrial robot, began working at a General Motors assembly line. Created by George Devol and Joseph Engelberger, this 4,000-pound robotic arm performed tasks too dangerous for humans, marking the beginning of robotics in manufacturing.
1964: ELIZA – The First Chatbot
Joseph Weizenbaum at MIT created ELIZA, the first chatbot that could engage in seemingly meaningful conversations. ELIZA's most famous script, DOCTOR, simulated a Rogerian psychotherapist, demonstrating early natural language processing capabilities.
1965: Expert Systems Emerge
Edward Feigenbaum and Joshua Lederberg developed DENDRAL at Stanford University, one of the first expert systems. This program could identify organic compounds from mass spectrometry data, proving that machines could perform specialized knowledge work.
The First AI Winter (1970-1980): Reality Meets Expectations
1973-1974: The Lighthill Report
British mathematician James Lighthill published a critical report on AI research, leading to significant funding cuts in the UK. This period, known as the “AI Winter,” was characterized by reduced investment and skepticism about AI's potential.

The Second AI Winter (1990-2000): Scaling Challenges
1987-1993: Expert Systems Decline
The limitations of expert systems became apparent as they proved difficult to maintain and scale. Many AI companies collapsed, leading to another period of reduced investment and research.
1997: Deep Blue Defeats Kasparov
IBM's Deep Blue made history by defeating world chess champion Garry Kasparov in a six-game match. This victory demonstrated that machines could outperform humans in complex strategic games, capturing global attention and renewed interest in AI.
“I could feel — I could smell — a new kind of intelligence across the table.” – Garry Kasparov after his defeat
