The next CEO of Apple is someone that cares about quality. (As evidenced by how good the hardware is)
I think it's important "what quality" they care about. Tim Cook cared about supply chain quality, and honestly he did an amazing job, but he didn't care much about software, vision of Apple, etc.
[1] to be clear, I stipulate Cook is indeed the world champion of Number Go Up. Nobody Number Goed Up more than Cook did. For Ternus to do Number Go Up to the same multiplier Cook did, I think he'd have to acquire all the other companies in the world.
