The interviews are arranged by subject, covering everything from science to spirituality, fashion to food, with the interviewees -- optimists and pessimists alike -- offering opinions in their area of expertise: Doris Kearns Goodwin on the future of the presidency and Bill Gates on the evolution of technology. Other authorities include Bob Costas on sports; Isaac Mizrahi on fashion; Maya Angelou on the arts; General John Shalikashvili, the Chairman of the Joint Chiefs of Staff, on the battlefield in the 21st century; and Stephen Jay Gould on the nature of man.
