I'm also not confident that a phone chip will be strong enough to run a LLM like ChatGPT within the next 5 years. I am aware of LLMs that can run on phones right now, but they're slow and they're incapable of tasks that require a moderate level of thought. I'm not optimistic about the capabilities of these exclusive features, if they are coming.
As long as apple prices their phones like how they are, they are never going to have total domination.
