Tim Higgins on the battle to take down Apple

Tim Higgins discusses his new book "iWar," examining how one of California's corporate crown jewels, Apple, faces an unprecedented rebellion.

As this battle imperils Apple's hold on the mobile world, the rise of artificial intelligence is threatening to potentially displace the smartphone era altogether.
