It seems an AI phone is going to also lock you into its own walled garden. So I’m not sure what this would solve.
What kind of AI phone did you have in mind? As it stands, it seems AI is an app or OS integration to smartphones as we know them today. Anything else seems like it would be too compromised as a product.
I stay with Apple’s walled garden, because it seems like the best option in terms of hardware, software, and services. I’ve tried Android tablets, Windows laptops, and use Linux on and off for various things. I don’t like any of it as well as what Apple, and the 3rd party developers on Apple’s platforms, put out. If Apple were to horribly fumble the ball on privacy and sell out their customers (they are going in the wrong direction in a lot of ways), I would have to seriously consider leaving, but I honestly have no clue where I’d go.
