I think I know what happened. The A-squad design team left Apple 15 years ago. The B-squad left 5 years ago. What remains is a sea of Gen Z designers who weren't yet alive when the foggy glass of Windows Vista seemed like a good idea.

We just have to wait for Gen Alpha to bring back flat design 10 or so years from today.
