App Library is a perfect demonstration of the adage that "Artificial Intelligence isn't." Mine has Audible, Clock, Settings, and Contacts in the first box, Craigslist, WhatsApp, something I don't recognize, and a folder of crap I don't use in the second, DDG, the App Store, Calculator, and another folder of crap in the third... Why would I ever use this?
EDIT: If it were marginally "intelligent," it would have a box for "listening to stuff" (Podcasts, Music, Audible, ...), "reading stuff" (DDG, Safari, Books, ...), "scheduling" (Calendar, Reminders, ...), etc. But I don't need AI constantly figuring these things out. I can put those apps in folders or known places on my home screen once, and never have to worry about them wandering around because an AI was trying to be helpful.
From Apple's support documentation (https://support.apple.com/guide/iphone/find-your-apps-in-app...): "The apps in App Library are organized in categories intelligently, based on how you use your apps. You can add apps in App Library to the Home Screen, but you can’t move them to another category in App Library." So I can't even make it less useless. Great.
