I get how people can get addicted to social media apps (I got addicted to FB when I was in college 2005-2007 ish), and I am happy to see articles like this and other media outlets cover social media addiction and spread awareness, its a big problem. I would not blame the apps, though.
I think the real problem is that social media turbo-charges the social dynamics of the real world:
* attention seeking - "likes" are attention, and people love attention
* social presentation - you can present the best picture of your fake life
* envy and fantasy - men and women who think they live boring lives observing the curated, filtered lives of the people they want to be
* social hierarchy - who follows who? Prettier people having more follower / friends
* etc
I fell into those traps, and fb/insta were there to indulge my insecurities - but, critically, it was insecurities that fed the into the addiction. I'm a different guy now - I spend more time on myself than observing others.
I'm poorly articulating all this, but I think there is something to be analyzed there.
