The Doomsday Equation Was Right for 30 Years

In 1960, the journal Science published a paper titled "Doomsday: Friday, 13 November, A.D. 2026." It wasn't a prophecy. It was a peer-reviewed calculation based on two thousand years of population data, and it said human population growth would spiral toward infinity on one specific date. That date is weeks away. For roughly thirty years, real-world data tracked the equation almost perfectly. Then the math broke. In this video: who wrote the paper, why it looked so accurate for so long, what changed after 1993, and what will actually happen on November 13, 2026. Along the way: the detail about the date that most retellings skip, and a second, very different warning the same scientist made about artificial intelligence in 1995. 00:00 The paper that named a date 01:00 The scientist behind the equation 05:00 Thirty years of looking right 09:00 Where the math broke 12:30 So what happens on November 13? 15:30 Final thoughts SOURCES Original paper: "Doomsday: Friday, 13 November, A.D. 2026" by Heinz von Foerster, Patricia Mora and Lawrence Amiot, Science, 1960 Heinz von Foerster, Wikipedia "Scientists predicted Friday 13 November 2026 will be doomsday.
