Big tech companies run out of new users to exploit and they end up collapsing (since in a capitalistic model you either grow or you’re doomed). With these companies going down, all the internet infrastructure goes down, unable to fight simultaneously the power shortages due to unavailable resources and the continuous strike of workers who cannot afford a livable wage anymore and civil wars in a world where natural disasters are more and more frequent.
With the internet down the society as we know collapses.
Now social media is people telling stories around a campfire.
Those who say dumb mean shit get slapped hard in the face.
Humankind’s healing process begins.
