You could keep using an iphone 14. It's the age cutoff for AI support.

This is my biggest concern. I've only stuck with Apple during this AI nonsense era because the parental/screentime controls allow to me completely shut it down, and I've never toggled it on in the Siri/AI options. It took a while but the 7GB they initially stole from me for the AI nonsense I'm not using eventually cleared itself out of storage.

I already have Siri limited to manual activation only. If they force all of this into Siri and I can't prevent AI models from actually installing their gubby hands all over the phone then that's it for me.
