I acknowledge that I'm still young, but I feel like Apple is introducing changes at a good pace. UI elements and layouts have stayed consistent.

Providing endless backwards-compatibility only bloats the interface and makes it harder to learn for new users. The goal must be slow but steady progress, so that everyone can adapt.
