TED Talk on IBM Watson
Here is a fascinating talk from a 2013 TED conference by Ken Jennings about his loss in 2011 to IBM's Watson, playing Jeopardy. This was a milestone not only for him personally - being replaced by a machine "at the only thing you're really good at" - but for the entire field of AI.
Much has happened in the field since 2013, but Mr. Jenning's talk really underlines the significance of AI in terms of the human condition.
