John Titor is one of the most enduring internet legends, originating from a series of bulletin board posts between 2000 and 2001. Claiming to be a soldier from the year 2036, Titor shared technical details of his C204 time travel machine and warnings about future civil wars and nuclear conflicts. His mission allegedly involved retrieving an IBM 5100 computer to solve a legacy code glitch. While his predictions didn't exactly come to pass, the mythos surrounding him became a staple of internet culture, inspiring anime like Steins;Gate and countless memes. Today, John Titor memes are used to mock failed prophecies, discuss time travel paradoxes, or satirize modern events as if they were predicted decades ago.
