You know this current backlash surrounding kids being glued to their phones . . . . I reckon it'll come good in the end. It will sort itself out as society learns to adapt & live with all this new fangled technology. The first wave of kids who happily threw away all their privacy & documented their whole lives on the early social media channels are the very same ones finding out how that can bite you on the arse later in life. They're raising their own kids now . . .
I used to work with some very clever propellor heads & when the fashion for your mobile phone was something about the size of your thumb, we knew smart phones were coming & no one could agree what size the screen would need to be.
Kids walking down the street oblivious to their surroundings . . . That cannot continue & I predict it will sort itself out when somekind of augmented reality delivered by somekind of HUD kicks in.
