I think we’re nearing a fork in the road moment here. Down one path is a continuation of the burgeoning social media landscape: people stop caring about their privacy altogether in pursuit of that next narcissistic hit. Down another, after all this crap is used to regularly humiliate people and control their public presence, there is a backlash and a push for more control over data (from the masses, not tech insiders who the masses don’t even really know about).
Personally: I think society will take the first one. If it ever decides to backtrack or shift, it will be long after my kids (currently small children) are adults or dead.
