The real problem for Apple here: in the fairly near future, the model of pre-defined functionality of software will be obsolete. All apps will be vibe coded and customized. Individual apps will basically be silos that protect proprietary data sources that are difficult to collect. But they will be infinitely more configurable than they are today.
I get annoyed enough when software I use changes arbitrarily in ways that don't benefit me, I can't see LLM vibed software that changes itself based on what it thinks I need being an improvement at all. It just feels like it would be even more annoying.
