I for one welcome our new computer overlords.

In 2011, IBM’s Watson computer system defeated human champions Brad Rutter and Ken Jennings on the quiz show Jeopardy!, marking a pivotal moment in artificial intelligence.
What happened: In 2011, IBM’s Watson, led by principal investigator David Ferrucci, competed on Jeopardy! against human champions Brad Rutter and Ken Jennings, winning the first-place prize of US$1 million. Watson was designed to answer questions posed in natural language, a significant challenge that required major advances in Question Answering technology. [1]
Why it matters: Watson’s victory demonstrated that machines could parse the puns, wordplay, and ambiguity of natural language in real time. This marked a shift from chess-style brute-force search to probabilistic language understanding, and launched IBM’s commercial AI strategy. Although the later pivot to healthcare would prove more challenging, Watson’s Jeopardy! win was a landmark event in AI’s development.

Why This Mattered
Watson's victory demonstrated that machines could parse the puns, wordplay, and ambiguity of natural language in real time. It marked a shift from chess-style brute-force search to probabilistic language understanding, and launched IBM's commercial AI strategy — though the later pivot to healthcare would prove far harder than a game show.
