I read the book then listened to Kara’s interview. Pretty clear she’s on the right side of this. The book was exactly what Vivian said: a glorified puff piece.
In the interview with Kara, Isaacson repeatedly hid behind a weak and sad “that wasn’t my role as biographer” defense.
@walter_isaacson, it is the very definition of your job to interview Vivian. As a fan of some of his previous work, it’s truly disappointing.
