It's not a push back against tech, but a push toward living in the moment. I've got plenty of technology, wouldn't want to live without it. There's such a thing as being overstimulated though, and also being too distracted. I reserve certain times for going online (i.e. whenever I want) but I'm not looking stuff up on Wikipedia and imdb every 5 minutes either, and when I put my tablet down I don't have notifitions on so it doesn't keep calling me after I decided I was done with it. I don't get texts but I have a phone, and I check my email once a day. It's called moderation.
I know at least one person though who if you tell them anything they are already turning their eyes to their device, looking it up and trying to inform themselves and also me about it. That's great but I bet you'll forget 5 minutes later when you're looking up the next thing, and also I'm trying to relate to you here by the way, not cram trivia in my short term memory. Or they're texting all during break and when they go back to work they're just IMing anyway on their work computer, what's the point of the break? They looked intense when they were texting and I bet they never got to relax.
