> You’re suggesting that because one person struggles with smartphone addiction, all of their friends and professional acquaintances should also give up their smartphones and not use them for social or professional interactions?

To an extent, I suppose so. That is not to say that everyone should abstain from smartphone use, but they should show some consideration in how they use it. For example, should they be using a social networking app for communication when a voice call or SMS will do? Likewise, should that staff meeting be held in a bar when it could be done on the business's premises?
