SoftBank Group CEO Masayoshi Son delivered a provocative warning about artificial superintelligence (ASI) during a meeting with South Korean President Lee Jae Myung on Friday, December 5, 2025, in Seoul. Son predicted that advanced AI could surpass human intelligence by a factor of 10,000, fundamentally altering humanity’s position in the cognitive hierarchy.france24+5​

“The difference between the human brain and that of a goldfish in a bowl is 10,000 times,” Son stated. “But it’s going to be different—we will become like fish, while they (the AI) will become like humans”. Son emphasized that while debates continue over artificial general intelligence (AGI), the focus should shift to ASI: “If ASI were only 10 or 100 times smarter than the human brain, I would not call that superintelligence. What I define as ASI is intelligence that is 10,000 times superior to the human brain”.finance.yahoo+2​

However, Son offered reassurance, comparing the future human-ASI relationship to that between humans and pets: “Just as we do not seek to harm our household pets, we can live peacefully with AI. There is no need for us to be consumed—ASI does not require protein”.koreaherald+1​

When President Lee asked whether ASI could potentially win a Nobel Prize in Literature, Son responded affirmatively: “I believe it will.” Lee replied, “I do not believe this is a desirable situation”.koreajoongangdaily.joins+1​
