Tech Professor Issues Stark Warning: AI May Slash Global Population to 100 Million

A computer science professor from Oklahoma State University is warning that artificial intelligence could trigger a massive population collapse, leaving Earth with just 100 million people by the year 2300. And it wouldn't happen through nuclear war or robot uprisings, he says. Just pure, relentless obsolescence.
'It's going to be devastating for society,' said Subhash Kak, author of The Age of Artificial Intelligence, in an interview with The Sun. 'I think people really don't have a clue.'
Kak believes that while robots will never become conscious, they will replace most human jobs, including those in law, education, and even relationships. That widespread redundancy, combined with the high cost of raising children, could convince future generations to stop having kids altogether.'There are demographers who are suggesting that as a consequence, the world population will collapse,' he explained. 'It could go down to as low as just 100 million people on the entire planet Earth in 2300 or 2380.'
That's roughly the population of the United Kingdom today, meaning massive cities like New York or Tokyo could become ghost towns. Currently, roughly eight billion humans live on the planet, so that's a dramatic change in the next few centuries.
Kak pointed to current birthrate trends in developed nations as a warning sign. 'People have stopped having babies,' he said. 'Europe, China, Japan—and the most rapid fall in population right now is taking place in Korea.'
Echoing Elon Musk's concerns about population collapse, Kak even floated the idea of building colonies in space to ensure humanity's survival. 'Should such a tragedy hit Earth, then it could be reseeded,' he said.
Whether we're headed for extinction or just dramatic downsizing, Kak insists the shift is already happening. 'What is absolutely certain,' he said, 'is that there is a population collapse occurring right before our eyes.'Tech Professor Issues Stark Warning: AI May Slash Global Population to 100 Million first appeared on Men's Journal on Jun 4, 2025

Study Finds 'Huge Surprise' About Ancient Humans in Africa

A new study published June 18 in the journal Nature has uncovered a 'huge surprise' about humans in Africa 50,000 years ago. Previous studies have shown that humans, who arrived in Africa 300,000 years ago and began leaving around 270,000 years ago, are descended from a small group of humans who left Africa just 50,000 years ago. Scientists have long wondered why earlier migration waves didn't leave any genetic traces in modern humans, and now the new study may explain why. To determine results, scientists analyzed evidence such as ancient plant and animal remains from various sites across Africa dating between 120,000 to 14,000 years ago. They reconstructed the habitats and climates in which people lived during those times to better understand the climate, rainfall, and vegetation of those environments. They discovered that modern humans actually began living around 70,000 years ago in the forests of West, North, and Central Africa, environments where temperatures were much harsher."Humans have been successfully living in challenging habitats for at least 70,000 years," study co-lead author Emily Hallett told Live Science. She added that the discovery was 'a huge surprise.' "Our ecological flexibility is part of what enabled our species to disperse across the globe and thrive in each habitat we encountered," she said. "What we see about 70,000 years ago is Homo sapiens becoming the ultimate generalist, and pushing into more and more extreme environments," co-author Andrea Manica explained. "That newly found additional flexibility gave them an edge 50,000 years ago, allowing them to spread rapidly across the whole globe, and thriving in environments that were novel and sometimes very challenging, such as those found at very northern latitudes." The discovery illuminates not only the evolution of humans in Africa, but the evolution of all mankind. Though it's unclear what began pushing humans out of Africa, the researchers say it was likely out of 'necessity.'

Kim Jong Un erases two officials from months-old state photos, prompting fears they were executed over botched warship launch: report

North Korea's despotic ruler Kim Jong Un appeared to have a top navy commander and another senior official erased from months-old official state photos following the nation's high-profile failed ship launch — fueling speculation that they were executed, according to a report. Admr. Kim Myong Sil and Hong Kil Ho, who operate Chongjin Shipyard, were expunged from the North Korean photographic record on orders of Kim — who blames them for the hermit kingdom's inability to launch a naval destroyer last month, NK News reported. 3 The original image released by North Korean state media that showed Admr. Myong Sil and Hong Kil Ho standing an arm's distance from hermit kingdom leader Kim Jong Un. KCTV The two North Korean honchos were originally pictured on the left side of the photo released by North Korean state media, near Kim. In the edited photos released by North Korean state media, there is now a conspicuously empty space where Myong Sil and Kil Ho once stood. The move was reminiscent of the Soviet Union's brutal dictator Joseph Stalin, who made common practice of erasing political adversaries from notable pics, including the infamously overt erasure of Nikolai Yezhov. 3 In freshly edited photos released by North Korean state media, Myong Sil and Kil Ho are absent. KCTV Kil Ho was blamed by the portly dictator and state media for the catastrophic failure to launch a 5,000-ton naval destroyer into the Sea of Japan on May 21. The warship became unbalanced as it was lowered into the water at the port of Chongjin, causing it to slide into the water — crushing and wrecking parts of the hull and leaving the bow stuck on the shipway, Korean Central News Agency reported at the time. Several officials were arrested at the shipyard directly after the shameful display, with experts believing Ho was one of at least four who faced repercussions, The Sun reported, citing experts. 3 The 5,000-ton naval destroyer slid into the water and caused major hull damage on May 21, but was successfully relaunched on Saturday. DigitalGlobe/Getty Images Admr. Sil has been a top navy commander in the isolated nation since Kim took power in 2011 —- but that is not likely to have saved him from the tyrant's bloodlust. 'If Kim Myong Sik fell on his sword, he may have avoided a public execution and saved his family and close associates from imprisonment,' Michael Madden, founder of NK Leadership Watch, told The Sun. 'On the other hand, if KJU is in a message-sending mood, then they may gather other top officials in the military and defense industry to watch,' Madden added. North Korea successfully launched the massive destroyer on Saturday in what state media described as 'convincing proof of the rapid transformation of [the North Korean] Navy.'

New Travel Ban Could Target Dozens of Countries, U.S. Memo Reveals

The U.S. government is reportedly considering a dramatic expansion of its travel restrictions, which could bar citizens from 36 more countries from entering the United States. According to an internal State Department cable obtained by Reuters, the potential expansion hinges on national security concerns and cooperation benchmarks. The memo, signed by Secretary of State Marco Rubio, outlined a 60-day window for these countries to address U.S. concerns or face partial or full travel suspensions. The list includes nations across Africa, the Caribbean, and parts of Asia, such as Angola, Ghana, Cambodia, and Syria. Citing issues like unreliable identity documentation, lack of cooperation in deportation cases, and visa overstays, the document emphasized the need to maintain the integrity of U.S. borders and public safety. The State Department pointed to passport security and anti-American activity as additional risk factors. While not all concerns apply equally to each country, the message is clear: cooperate or face consequences. If enacted, this would mark one of the largest expansions of U.S. travel restrictions in recent memory. Earlier this month, a proclamation suspended entry from 12 countries under similar national security justifications. Now, with this latest proposal, that number could more than triple. A senior State Department official declined to discuss the specifics of the memo but emphasized that visa policies are under constant review to ensure the safety of Americans. For travelers with ties to any of the listed nations, or for global mobility at large, the potential fallout could be significant. Business trips, academic visas, family reunifications, and tourism could all be impacted by this travel ban expansion depending on how the final policy takes shape. As the 60-day clock begins to tick, all eyes are on diplomatic responses and whether these countries will meet the U.S. government's requirements, or risk being shut Travel Ban Could Target Dozens of Countries, U.S. Memo Reveals first appeared on Men's Journal on Jun 15, 2025
