Evolution of AI
Tracing the technological milestones from philosophy to foundational models.

Deep Learning Era
AlexNet utilizes GPUs to revolutionize image recognition, leading to today's LLMs.
The quest for artificial intelligence began long before computers existed, in the myths and philosophical debates of ancient civilizations. However, the scientific foundation was laid in the mid-20th century. In 1950, British mathematician Alan Turing published 'Computing Machinery and Intelligence,' where he proposed the 'Turing Test'—a criterion for intelligence that asks if a machine's behavior can be indistinguishable from a human's. Turing famously asked, 'Can machines think?' and provided a roadmap for building programmable machines that could simulate logic.
The formal birth of the field occurred at the Dartmouth Workshop in 1956. Organized by John McCarthy and Marvin Minsky, this event brought together scientists who believed 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.' During the 1960s, early successes like ELIZA (the first chatbot) and SHRDLU created immense optimism. Researchers predicted that a machine would beat the world chess champion within a decade—a feat that actually took forty years to achieve.
The modern era of AI began in the late 1990s and early 2000s, driven by 'Big Data' and the internet. In 1997, IBM's Deep Blue defeated Garry Kasparov, the world chess champion, marking a major milestone. But the truly pivotal moment came in 2012 with 'AlexNet.' Researchers used Deep Learning and GPUs to achieve a massive leap in image recognition accuracy. This sparked the current 'Deep Learning Revolution,' leading to the development of self-driving cars, real-time voice translation, and eventually, the Large Language Models (LLMs) like GPT-4 that we use today. We have moved from machines that follow scripts to machines that learn from the entire sum of human knowledge on the internet.
The AI Winters
In the 1970s and late 1980s, the field experienced 'AI Winters.' These were periods where funding and interest dried up because the technology failed to live up to the massive hype. Computers were simply too slow, and data was too scarce to support the ambitious goals of early researchers. These periods taught the community that building intelligence is far more difficult than simulating logic.
