Steve Jobs and Bill Gates never worked for each other, yet for three decades their companies defined the same industry by opposite instincts. The film traces both from the beginning, Jobs and Steve Wozniak building the Apple I in a garage, Gates dropping out of Harvard to write software for the Altair, through the deal that let Microsoft's operating system ship on IBM machines and made Gates rich while Apple stayed a boutique player. It follows the Macintosh launch and the graphical interface fight that followed, with Jobs accusing Gates of stealing Apple's look and Gates pointing out that both of them borrowed it from Xerox PARC. Archival interviews, product footage, and period news coverage carry the story through Jobs's ouster from Apple, his return to rescue a nearly bankrupt company, and the surprising 1997 investment Microsoft made to keep its rival alive. The film treats the two men as rivals who needed each other, ending with Gates's tribute after Jobs's death.
