Advising kids to lean away from modern life and push back on the progress of distracting technologies will actually be a more anti-social move than not.
What I mean is that to exist and live in the modern world increasingly requires adept skills at managing bespoke technological platforms. To be a social being in the 21st century is largely about navigating these platforms and being 'plugged in'. Disconnect, and you'll miss out on the flow of humanity.
I mention I don't like this because frankly, I miss the idea of small towns with supportive communities that had inherent dependencies on each other. The baker, the butcher, the doctor, the pastor, etc, everyone had a feeling of purpose and a connectivity to their community. Of course this ideological view of society is long gone so there's just no sense trying to push back. Accept that today's child is a highly connected, distracted, techno-proficient being and let that be that.
