Talking to an audio-enabled LLM is definitely "simpler" in terms of device interaction than navigating menus and such. Also having less GUI focus would feel simpler to me.

I find myself missing the experience of earlier iPhone where it didn't feel like I had so much crammed into my phone.

I can imagine using a device that I interact with primarily by talking with it, and the GUI is secondary or non-existent. For the bulk of what I use my phone for other than consuming video / doom-scrolling (which I could use much less of anyway), I think a voice interface would be preferable.

Initially "Apple Intelligence" was very exciting to think about, in that having a Siri that you could actually talk to would have a lot of possibilities, but we've seen essentially no progress in that direction.
