I’m impressed to see what the Photos app is able to generate and distinguish, only computing data locally. The Photos app is also pretty accurate when recognising faces and objects. This compliments nicely the memories it is able to put together in nicely theme-matched videos. In addition to the above, Kay also provides a complete list of things the Photos app can be queried for as well as the categories to which they belong to. This list will continue to grow over time and it could easily be part of OTA updates. As Craig Federighi said in John Gruber’s The Talk Show (53:40)
There is this idea that if you don’t have the data, how would you ever learn? As it turns out, if you wanna get pictures of mountains, you don’t need to get it out of people’s personal photo libraries.
