Paratviden vidunderet Ken Jennings har lavet en karriere ved at være en vogter for paratviden; han har vundet flest spil i træk på den amerikanske Jeopardy. Men i 2011, spillede han en udfordrende kamp mod supercomputeren Waston -- og tabte. Men humor og ydmyghed, fortæller Jennings os hvordan det føltes bogstavelig talt at blive slået af en computer i sit eget spil, og slår også et slag for god, gammeldags menneskelig viden. (Filmet ved TEDxSeattleU.)

Ken Jennings: Watson, Jeopardy og jeg, den forældede alvidende

Losing to a supercomputer on a televised quiz show forced a hard look at the value of human memory in a digital world. As technology surpasses people in sheer recall, the ability to quickly draw on knowledge can still change lives, as when a ten-year-old saved over 100 lives during a tsunami by remembering a single geography fact. In a time when information is doubling every 18 months, what we know shapes crucial choices and connects us to one another. Preserving a shared cultural memory keeps society resilient as technology evolves.
