Yeah, and how much do you want that on your phone? And how many people do you think want/need that on their phones?
I can tell you, I'm a software developer and there's currently maybe one product in my workflow that involves ai, and I'm not even sure about that one. Sure, that might change in the future, but not on my phone. Why would it?
AI is not magic. It has its uses, but the current iterations offer nothing even remotely relevant for the average user to have on their phone.
