I'm sure Apple will roll something out in the coming years. Now that just anyone can easily AI themselves into a picture in front of the Eiffel tower, they'll want a feature that will let their users prove that they _really_ took that photo in front of the Eiffel tower (since to a lot of people sharing that you're on a Paris vacation is the point, more than the particular photo).
I bet it will be called "Real Photos" or something like that, and the pictures will be signed by the camera hardware. Then iMessage will put a special border around it or something, so that when people share the photos with other Apple users they can prove that it was a real photo taken with their phone's camera.
This exists, the standard is called C2PA, Google added support for it in the Pixel 10. I was surprised and disappointed that Apple didn’t add support for it in the most recent iPhone! A few physical cameras are starting to support it too (https://yawnbox.eu/blog/c2pa-camera/)
How "real" are iPhone photos? They're also computationally generated, not just the light that came through the lens.
Even without any other post-processing, iPhones generate gibberish text when attempting to sharpen blurry images, they delete actual textures and replace them with smooth, smeared surfaces that look like a watercolor or oil paintings, and combine data from multiple frames to give dogs five legs.
