Introduction: After the Gold Rush, a Chill Sets In π€ #
The boundless optimism that erupted from the Dartmouth Workshop fueled a “golden age” of AI research. 1 Researchers made bold predictions, and governments invested heavily, certain that thinking machines were just over the horizon. But reality proved to be far more complex than anticipated. The promises made in the 1960s began to outpace the actual progress, leading to a period of deep skepticism and funding cuts. This era became known as the AI Winter: a time when the field went into hibernation to reckon with its own limitations. 22

The Promise vs. The Reality: The Trouble with Early AI π€ #
The dominant approach to AI in these early days was Symbolic AI, often nicknamed GOFAI (Good Old-Fashioned AI). 3 The idea was to program computers with a set of logical rules about the world and have them use those rules to reason.
This approach worked remarkably well for “toy problems”βsimple, self-contained tasks like playing checkers or solving algebra equations. The success in these limited domains led researchers to believe that scaling up to solve messy, real-world problems would be straightforward.
They were wrong. The real world is filled with ambiguity, nuance, and an almost infinite number of variables. The rule-based systems of GOFAI broke down under this complexity. A program that could solve a logic puzzle couldn’t understand a simple children’s story or identify a cat in a photograph.
The Storm Arrives: The Lighthill Report π¬οΈ #
The growing gap between promises and results eventually led to a major backlash. A pivotal moment came in 1973 with the Lighthill Report in the United Kingdom. 4 Commissioned to evaluate the state of AI research, Professor Sir James Lighthill delivered a damning verdict, concluding that AI had failed to achieve its grandiose objectives and that its methods were not scalable to real-world applications.
The report was devastating. It led to severe funding cuts for AI projects across the UK. A similar trend followed in the United States, as government agencies like DARPA diverted money away from fundamental AI research. The first AI Winter had officially begun.
A Cycle of Boom and Bust ππ #
This first winter was not a one-time event but the beginning of a pattern. The story of AI throughout the late 20th century is marked by these cycles of funding and disillusionment. 5 A new technology (like “expert systems” in the 1980s) would emerge, sparking another wave of hype and investment, only to be followed by another “winter” when the technology inevitably failed to meet the inflated expectations.
These winters, however, were not a total loss. Like a forest during a real winter, the field was not dead, but dormant. 6 It forced the most dedicated researchers to abandon hype and focus on a different, more powerful approachβone based not on programming rules, but on learning from data. This fundamental shift would eventually lead to the AI spring we see today. 7
