A selection of dystopic futures:

• Totalitarian government controls our very thoughts and prohibits sex. Barcodes tattooed on everyone’s foreheads.
• Ravening undead spread across the globe seeking brains to consume. Shotgun and chainsaw prices skyrocket.
• Emboldened by death of Charlton Heson, marauding aliens enslave humanity, force us to build enigmatic monuments to confuse future archaeologists.
• End of oil leads to an BDSM-inspired biker gangs battling through an anarchic desert landscape.
• Giant astroid headed for Earth, government efforts to stop it held up by bureaucratic red tape. Survivors envy the dead.
• All social interaction conducted through Facebook, and food rations are determined by how many friends we can get to add our application.
• Newly-sentient computers make war on their creators, humans acquiesce to machine rule, having forgotten how to live without email.
• Current packaging trends carried to their logical conclusion. With all food encased in impenetrable blister packs, humans starve to death.
• Environment trashed, humanity attempts to flee to a new planet, only to realize that no one ever really bothered to figure out interstellar space flight.
• Proliferation of antibacterial hand washes leads to an outbreak of drug-resistant pinkeye that decimates humanity.
