That's not the point. Those profit margins will fall dramatically and Apple will decline as a company and/or possibly move to a backseat-type of a company, maybe moving into electric automobiles....things that other companies like Tesla are already doing very successfully.
The point is, Steve was one of those guys at the top of a huge company telling people that this sucks, or this is good, release that, etc. He knew what people needed/wanted before anyone else.
Like I said, Tim is a numbers guy. He sees numbers go up in an area and puts more into that category so they can make more money. He is Steve's protege since 1997 after all.
Apple relies 70% of their profits on iOS devices and that will decline due to democratization of mobile devices. All mobile devices look the same now and have similar functions. Chinese manufacturers like Xiaomi are closing that gap as well, especially in the "Affordable premium" mobile devices.
Apple needs a new leader, Tim is, like I said, a numbers guy and wants to please the board and stockholders.
Apple, historically, did well when it broke new product lines. Some were good, some were bad. That's what kept Steve going, in my opinion. He took big risks.
The Apple Watch is not a huge risk, and I bet you that was even a project on the back burner that Steve worked on.
The decline of Mac sales and iOS sales is a sure sign of an end to an era.
