My experience is limited to my elderly parents who have trouble seeing. With the text size Apple allows them to set it to, their phones are unreadable. Text runs off the screen in every app, 1st and 3rd party.

In their bill example, the user is told to confirm with the provider. Why not offer to call the number on the bill? Instead of telling them to use text detection, do it for them? Presumably Apple Intelligence would already have that capability. I’m afraid this will be a gimmick at best.

EDIT: Forgot to mention, the grip is good to see. Hopefully they don’t charge the apple tax on it.

Even better, fire up Orca (or whatever screenreader application your OS comes with) yourself and try to use your computer while shutting your eyes, kind of eye-opening (no pun intended) what kind of experience these sort of users typically get. And also, you quickly start to understand why they set the speech rate for their voice synthesizer to be so fast, it's almost unbearable navigating applications (and particularly lists) otherwise.

my go to example of this is this talk by Saqib Shaikh (a blind software engineer at Microsoft) giving a talk about Visual Studio. Link is timestamped
