Anecdotally, but I'm already seeing it in high school age kids. These kids haven't really grown up without access to a smartphone, and you can tell the difference in how they interact with each other. There's a lot less social talking, and they don't understand emotions or empathy very well at all. And heaven forbid you try to get them to put down the damn phone and take notes or do something.

"Why do I need to learn this when photomath does it for me?" was often heard, or they'd just Google the answers because they're there. They work a lot less hard to try to get stuff, and it hurts their discipline and focus, for sure. And I'm going to stop my rant there, because I could continue on with it forever.
