I'm inclined to agree. We have made ourselves incredibly reliant on mobile phones & social media.
I found myself driving home from work. Why? Because I left my mobile phone there. I question my own sanity.
Many people live their lives on social media (says the guy who gets paid to work on social media). We also feed off each other's anxieties, increasing hysteria. Mobile phones give us the expectation of instant, on demand, 24/7 contact.
My missus, for example, never bothers charging her phone & frequently leaves it out of earshot. Conversely, if I don't answer mine within the first two rings, I'll come out of meetings with a dozen or more missed calls from her.
Sometimes it's nice to go off grid for a few days and unless the person doing it is at significant risk, it seems completely normal to me. Maybe I'm just OLD.
Old, you're old not odd. As jim has said it is very much a change in pattern that should be the trigger. For a large part of the community constant and persistent connectivity is the norm and every second of ones day is an open book.
I'm a child of the computer revolution however I have slowly crawled into to each phase of the brave new digital world. I had a BBC Micro at school and a Acron Electron at home. I went round to my mates to home-brew games and apps on his Spectrum or my Acorn. I hacked my first game, Elite, and from there on I have been at the edge of a bow wave of connectivity. I had internet and email in the 90s, I only knew one other person with email - a fellow geek who was in a cabin two down from mine in Moscow Camp NI. We email each other and then shouted down the corridor to make sure each other login to read it........
Now my four year old son is learning to count using the iPad, he can record using the camera app and is able to understand games and how to play them. It's frightening.
The generation behind me is all about connections, either real or virtual. If the kids of my friends who are 16 to 20 years old suddenly stopped using the online world it would be a strong combat indicator something is wrong.
Its classic warfare, you build your maritime picture so you know what is normal and can spot the abnormal. There is a very good company out there that I have worked with who are able to pull together the digital world, along with on ground observations, to deliver a stunning Common Operating Picture (COP) that covers everything that has an in/out - CCTV, phones, internet, Internet of Things, EM spectrum analysis... everything. From that they can spot changes a they occur far quicker than a human and deliver I&W at a speed that is incredible. As our lives become more dependant on being digitally connected it will be harder to go off grid without standing out.
