Modern Artificial Intelligence (AI) traces its formal beginnings to the mid-20th century. A defining milestone was the 1956 Dartmouth Workshop, where researchers gathered to explore the possibility of creating machines capable of human-like intelligence. This event is often recognized as the birth of AI as a dedicated field of study. In the decades that followed, AI research went through alternating phases of optimism and challenge. Periods of rapid progress, fueled by breakthroughs in algorithms and computing power, were often followed by slower periods when expectations outpaced available technology — sometimes called “AI winters.” Despite these cycles, each wave of enthusiasm contributed valuable theories, methods, and tools that laid the foundation for today’s advances. The evolution from symbolic reasoning in the early years to machine learning and deep learning in the modern era highlights AI’s continuous growth and resilience as a discipline.
Timeline of Modern AI
