It's just a phase, just like how television used to be 'the thing' to do. As technology matures it will tackle all the downsides of smartphones. Maybe we will have holograms or augmented reality glasses, who knows.
It's not that millenials are not ready for the world; it's just that the world is outdated for millenials. The way we think they should act, is the old way, just like how our grandparents always used to hammer it into us that their old skool way was much healthier and better.
TL;DR: We are turning into our grandparents
haha I see - we do. I just hope that the technology will be better for our health in the future. Of course it´s just a phase, totally agree with you! But will the new technology be better or worse ? Nobody knows
