It’s slated for 7:30 p.m. at the Boys Town Music Hall, 13715 Flanagan Blvd. The festival runs April 1 through April 30. During his keynote, Jennings will share the behind-the-scenes account of his 2011 battle with IBM’s “Watson.” The super-intelligent computer was designed to beat the world’s best “Jeopardy!” players.
Jennings watched “Jeopardy!” daily and dreamed of becoming a participant. He first appeared on the show in 2004, leading to a 74-game win streak. In 2020, he was named the show’s “Greatest of All Time” after competing with fellow champs James Holzhauer and Brad Rutter.
