Scott wouldn't have been fired had Steve lived a few more years. Steve LOVED skeuomorphism ("When people see these icons, they should want to LICK them") and him and Scott were pals. If Steve had lived to see the argument during the iOS 6 Maps incident (which was wildly overblown) he would likely have defended Scott. The only reason they got away with firing him was simply because Steve 'conveniently' died shortly before.Yep.
And while he obviously wasn’t there for Scott’s firing and Johnny’s takeover, I wouldn’t be shocked to find out that Steve had a hand in the earliest talks of the iOS 7 era flattening, given that apple is usually working on the next several operating systems at the same time.
If Steve had been in the same room as Ive when Ive had decided to flatten iOS 7 I can imagine he'd frown, say 'Nope' and walk out the room.
All I can imagine is that if skeuomorphic UI would have continued development, it would have made the Vision Pro even more exciting. I can only dream of what it could have evolved into, such as the UI we saw depicted in the first two Iron Man films (I still wanna 'toss' a file into the 'bin' like Stark did)
