In the future kids will be traumatized by illegal chartrooms. don’t chat with anyone you don’t know! will be the most common advice given to kids by their parents.
Sleeping pills will have massive demand and people will rely on them to get some rest after staying up bleary eyed in front of PCs chatting idly away.
Zombies will be commonplace as people wave their hands about in front of their face in a 'touch screen delusion' where they try to move the real world around like they move objects around on a pc.
A few generations later...
Aliens will land on earth and find an empty planet. All the people will be in sealed compartments that they will be put into as soon as they are old enough to leave the family pod. Which is a temporary social institution formed to honor a genetic obligation.
Goods will be transported via holographic molecular displacement. Atomization will require only commands from individuals in pods who will operate Earth’s complex infrastructure.
The more progressive thinkers would have already outsourced their thoughts and brains to twitter.
Sexual stimulation will exclusively happen through the art of cyberdildonomics.
The aliens will destroy the planet, thinking it’s empty, to make way for an intergallactic superhighway and yes they will be known as Vulcans, if you like.
