There is value, yes. However, things are rarely so black and white as the commenter above you sees it wherein one could simply disconnect entirely. The reality of it is within our current zeitgeist the digital world is unavoidable - be it in the workplace, the condensation of our activities (incl. unavoidable ones- banking, etc) into apps on our phones.

Of course this is barring the idea of withdrawing all ones savings and moving onto a farm and living off the land :D.
