From my point of view, Jony Ive’s departure is not because Apple is in trouble. Why? Because, if Apple is in trouble, then I’ll have to revisit my understanding of capitalism.
Apple is certainly in transition. Just by looking at Apple’s current leadership page, design has certainly been demoted compared to a few years ago. Does that mean design is no longer at the center of everything at Apple? I don’t know. Very few of us can tell. It will take a few more product releases to see how things evolves from now.
My bet is that a few people in the current design team are silently filling the void and bring with it a breath of fresh air.
