AS A TEENAGER in Oregon, Jensen Huang was one mean ping-pong player. In 1978 his mentor, Lou Bochenski, described him in a letter to Sports Illustrated as “perhaps the most promising junior ever to play table tennis” in the American north-west. Had he been a bit older, who knows, he might well have joined Bochenski’s daughter, Judy, who toured China in 1971 as part of Richard Nixon’s “ping-pong diplomacy” initiative to improve relations between the capitalist and communist worlds.
