History

Historical Context

In February 2011, IBM’s Watson defeated Jeopardy! champions Ken Jennings and Brad Rutter, showcasing commercial AI’s capacity to process natural language in the United States. Watson ran on 90 servers delivering 2.5 petabytes of data, costing roughly $100 million in development and hardware for healthcare analytics and research. OpenAI’s GPT-6 Astra, built on Nvidia’s Grace Blackwell superclusters and announced by CEO Jensen Huang, now processes tasks 47 % faster than GPT-5.6. The Watson breakthrough foreshadowed today’s accelerated race toward general-intelligence systems, prompting stricter cybersecurity controls and heightened industry scrutiny among regulators.
