As recent decades have progressed and more of our lives have gone digital, self reported rates of loneliness, isolation and depression have been skyrocketing. It's sometimes called the Internet Paradox - a technology that is supposed to increase our connection is correlated with increased feelings of isolation.

It's been the subject of study but it's impossible to truly reject the hypothesis due to the ubiquity of the effect - there's no control group. Obviously correlation is not causation, but I think the severity of the effects warrant further thought and investigation.
