Geoffrey Cain argues that Jobs' exile was crucial for his growth. At NeXT, his ego and obsession with vision over execution led to an overpriced, unreliable computer. In contrast, at Pixar, he learned to step back from creative control and focus on business, creating a stable and profitable venture. These experiences taught him patience and the importance of a long-term view for both products and people. This transformation culminated in his return to Apple, where he built a stable team that created the iPhone and iPod, resulting in one of the greatest business comebacks.
