Just a tongue-in-cheek comment. I agree, only partially though, as I am not an absolutist.
Yes, there are several Apple innovations on prior art -- no question. Even some new art (FaceID). But Apple has dropped some
fubar attempts as well which begs off the
"second but best" meme: e.g. Maps and Siri (need say more?).
So let me summarize my view: The present strength of Apple lies entirely on its purposely-built silicon, as no-one can match the capabilities derived by that silicon:
"People who are really serious about software should make their own hardware" -- Alan Kay
And, only time will tell, if the present leadership is up to the task to marry software to that hardware, and not drop the ball, in the absence of SJ's dogmatic guidance.
