Arkady Yurievich Volozh seemed to be in good spirits. It was February 11, his birthday, and the 58-year-old billionaire CEO and cofounder of Yandex, the Russian tech behemoth, was in the sort of open, engaging mood that could be called privetliviy, after the casual Russian word privet for hello. He was speaking from his car in Tel Aviv, bragging about his father—an oil geologist in his eighties who had “discovered” oil in Israel, Volozh said—as we chatted about my upcoming trip to Tel Aviv to interview him for this story.
