I recently got a new iPhone for the better camera. Did this rather than getting a camera. Now I'm wondering how long it'll be before cameras will also have CSAM scanning. It also leads me to this question about CSAM. If it only recognizes existing photos, then it's of no use for photos that I take. So perhaps CSAM on a dedicated camera will never be a thing, and people will gravitate back to such cameras. Also leads to this question. If Apple isn't scanning my photos ( for which there is no CSAM fingerprint), what photos are they scanning? Things that showed up in my browser?
