Thanks for the clarification. My family library is around 1Tb, the weakest device is an iPhone SE, and the most used access is through a web browser. Does on-device machine learning (provided you're syncing inter-device) work in that scenario ?
If I can interrupt.. Wow, 1TB of photos? This is just astonishing to me. What is the use of so many images? As an ex semi-pro photographer, one of the things I realized is that what makes photographs special to people, even family photographs, is the rarity of them. So I just cannot understand taking and holding on to this many images. I would find just managing the images would take away time and money from my famil…
For me the problem is that I'm not a great photographer. I take loads of bad photos. It would take me far too much time to go through all of them and decide which ones to keep.
Also, my wife and I sometimes look at old photos for reasons that have nothing to do with the quality of the photo or even with reminiscing. Instead, we may look for some specific fact (mole, dental issue, dress, haircut, domestic repairs, flooded footpaths, etc). The more photos we keep, the more likely it is that we can find what we're looking for.
