Apple should be extremely worried about the AI companies making big improvements in UX. This work by OpenAI is a step in that direction.

If the main user paradigm becomes a chat interface conjuring whatever UI elements needed to best accomplish the task at hand, the entire paradigm of OS, UI frameworks, apps from an App Store to accomplish specific tasks, all come into question.

I keep thinking that Steve Jobs would have been all over the UX ramifications of LLMs and demanding that Apple lead in that area.
