> Apple --> OpenAI can make a device that runs ChatGPT as the OS instead of relying on iOS.

Yeah... No they can't. I don't agree with any of your "disruptions," but this one is just comically incorrect. There was a post on HN somewhat recently that was a simulated computer using LLMs, and it was unusable.

I find myself doing more and more inside ChatGPT. When ChatGPT inevitably can generate GUIs on the fly, book me an uber, etc. I don't see why iOS wouldn't have competition.
