Steve may have just gotten lucky to find him, but Ali Ozer ended up shaping the NeXTStep libraries that became Cocoa (when naming infrastructures after hot drinks became the rage ;-), and has maintained his control of shaping ever since.

So Jobs got "lucky" (luck favors the prepared, of course) in his finding Ali to obsess about the NS and Cocoa libraries in all dimensions, with the same kind of taste-making abilities as Jobs had at the larger whole ecosystem level.
