I've come across an article that steps back from an individual addiction focus and looks at our societal level of addiction to technology and its possible consequences: https://www.tandfonline.com/do...3311908.2016.1157281
The article outlines two areas of concern: reduced productivity, and insufficient input to our neurocircuitry. For productivity, they call for more research examining the optimal level of technology use before the many distractions detract from human performance. For our neurocircuitry, they suggest that our basic needs (i.e. connection, seeking novel experiences, etc.) are insufficiently being addressed through technology, resulting in 'atrophy of the social mind' among other results.
