John Sculley fired the late Steve Jobs back in the day. Jobs then 30 years old, bought NeXT and opened Pixar. While Sculley blames the board and regrets not calling Jobs back to the company, I believe this was one of the best things to happen to Jobs.
I believe during the initial days of building Pixar, did Jobs realize that all this while, he was building the perfect computer, but not a legacy.
In his own words to John Lasseter, a Pixar animator who then become the CEO of Pixar, the computers he created can oly last at most 3 years, before going obsolete. Lasseter, on the other hand, has a chance to create a product that lasts forever if done right.
Both of them (Jobs and Lasseter) then went on to create their own masterpieces that becomes their legacy.
