[The Financial News] Elon Musk, chief executive officer of Tesla, has issued a stark warning by linking South Korea’s low fertility problem to a potential security crisis.
Appearing on the “Moonshots” podcast hosted by Peter Diamandis, released on the 7th (local time), Musk discussed the future of humanity, Artificial Intelligence (AI), and demographic shifts.
In that context, he brought up South Korea as an example of the population crisis.
“South Korea’s fertility rate is about one-third of the replacement rate needed to maintain its current population. Isn’t that truly astonishing?” he remarked.
He went on, “If this trend continues, South Korea’s population will shrink to about 3% of its current size in three generations. That’s roughly one twenty-seventh of what it is now,” adding, “At that point, the Democratic People's Republic of Korea (DPRK) wouldn’t even need to invade. They could just walk south across the border.”
Elon Musk has repeatedly described South Korea’s low fertility as a grave problem and voiced deep concern.
In a March 2023 interview with Fox News, when asked what he fears most about humanity’s future, he answered “low birth rates” and singled out South Korea. In 2022, he also wrote on X (formerly Twitter) that South Korea, along with Hong Kong, is experiencing the world’s fastest population collapse.
