Adam Lashinsky via Cult of Mac:
Jobs himself believes he has set Apple on a course to survive in his absence. He has created a culture that, while not particularly jolly, has internalized his ways. […]
His mission: to turn the traits that people most closely associate with Jobsâ€“the attention to detail, the secrecy, the constant feedbackâ€“into processes that can ensure Appleâ€™s excellence far into the future.
Steve Jobs is the essence of Apple. While I think Apple will not only survive, but continue to thrive, without having Jobs on campus day-to-day, a culture dissipates over time. And over time you need Steve Jobs to inject himself into Apple’s culture to purify it.
