Steve’s DNA will always be the base for Apple. It’s the case now. I want it to be the case in 50 years, whoever’s the CEO. I want it to be the case in 100 years, whoever’s CEO. Because that is what this company is about. His ethos should drive that—the attention to detail, the care, the ­simplicity, the focus on the user and the user experience, the focus on building the best, the focus that good isn’t good enough, that it has to be great, or in his words, “insanely great," that we should own the proprietary technology that we work with because that’s the only way you can control your future and control your quality and user experience. And you should have the courage to walk away and be honest with yourself when you do something wrong, that you shouldn’t be so married to your position and your pride that you can’t say, “I’m changing directions." These kind of things, these guardrails, should be the basis for Apple a century from now.

It should remain the same. I think of it as a North Star. It’s always important to have that in mind as you make decisions. It ­actually makes decision-making much simpler.

It’s actually not about competing, from our point of view. It’s about thinking through for the Apple user what thing will improve their lives.
