Machines may soon think in a language we don't understand, leaving humanity in the dark: Godfather of AI sounds alarm
Synopsis Artificial Intelligence pioneer Geoffrey Hinton cautions about AI's future. Hinton suggests AI could create its own language. This language might be beyond human understanding. He expresses regret for not recognizing the dangers sooner. Hinton highlights AI's rapid learning and knowledge sharing capabilities. He urges for ethical guidelines alongside AI advancements. The goal is to ensure AI remains benevolent. Agencies Geoffrey Hinton, the "Godfather of AI," warns that AI could develop its own incomprehensible language, potentially thinking in ways beyond human understanding. Hinton, a Nobel laureate, regrets not recognizing the dangers of AI sooner, emphasizing the rapid pace at which machines are learning and sharing information. Geoffrey Hinton, often dubbed the 'Godfather of AI,' has once again sounded a sobering alarm about the direction in which artificial intelligence is evolving. In a recent appearance on the One Decision podcast, Hinton warned that AI may soon develop a language of its own — one that even its human creators won't understand. 'Right now, AI systems do what's called 'chain of thought' reasoning in English, so we can follow what it's doing,' Hinton explained. 'But it gets more scary if they develop their own internal languages for talking to each other.' He went on to add that AI has already demonstrated it can think 'terrible' thoughts, and it's not unthinkable that machines could eventually think in ways humans can't track or interpret. Hinton's warnings carry weight. The 2024 Nobel Prize laureate in Physics, awarded for his pioneering work on neural networks, has helped lay the foundation for today's most advanced AI systems, including deep learning and large language models. But today, Hinton is wrestling with what he calls a delayed realization. 'I should have realised much sooner what the eventual dangers were going to be,' he said. 'I always thought the future was far off and I wish I had thought about safety sooner.' That hindsight is now driving his advocacy. Hinton believes that as digital systems become more advanced, the gap between machine intelligence and human understanding will widen at a staggering pace. One of Hinton's most compelling concerns is how digital systems differ fundamentally from the human brain. AI models, he says, can share what they learn instantly across thousands of copies. 'Imagine if 10,000 people learned something and all of them knew it instantly — that's what happens in these systems,' he explained on BBC News . It's this kind of distributed, collective intelligence that could soon allow machines to outpace even our most ambitious understanding. AI models like GPT-4 already surpass humans in general knowledge, and though they lag in complex reasoning for now, Hinton says that gap is closing fast. While Hinton has made waves by speaking openly about AI risks, he says others in the tech world are staying quiet — at least in public. 'Many people in big companies are downplaying the risk,' he noted, despite their private concerns. One exception, he says, is Google DeepMind CEO Demis Hassabis, who has shown serious commitment to addressing those risks. Hinton's own exit from Google in 2023 was widely misinterpreted as a protest. He now clarifies, 'I left Google because I was 75 and couldn't program effectively anymore. But when I left, maybe I could talk about all these risks more freely.' With AI's capabilities expanding and governments scrambling to catch up, the global conversation around regulation is intensifying. The White House recently unveiled an 'AI Action Plan' aimed at accelerating innovation while limiting funding to overly regulated states. But for Hinton, technical advancements must go hand in hand with ethical guardrails. He says the only real hope lies in finding a way to make AI 'guaranteed benevolent' — a lofty goal, given that the very systems we build may soon be operating beyond our comprehension.

Indian teens excel at Global Linguistics Olympiad with gold, bronze & rare feat
Hyderabad: A love for decoding rare languages and decrypting clues has helped a team of four young boys, guided by a professor from the International Institute of Information Technology, Hyderabad (IIITH), bag a gold and a bronze medal at the 22nd International Linguistics Olympiad (IOL) held in Taiwan. The team comprised 15-year-old Vaageesan Surendran from Chennai, 12-year-old Advay Misra from New Delhi, 18-year-old Nandagovind Anurag from Bengaluru, and 15-year-old Siriparupu Bhuvan from Hyderabad. They also received two individual honourable mentions and one for the entire team. Parameswari Krishnamurthy, a professor at IIIT-Hyderabad, led the team, while Anshul Krishnadas Bhagwat, an undergraduate researcher at the institute, accompanied them as an observer.

"I found the IOL's challenge fascinating. Some problems were easy, others were hard, but all of them were interesting and captivating," said Vaageesan, who is fluent in English, Mandarin, Spanish, and Hindi, in addition to his mother tongue, Tamil. Impressively, he can read the scripts of 34 different languages. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 20 Pieces of Clothing you Can be Too Old for Learn More Undo This year's edition saw 227 contestants from 57 teams representing 42 countries and territories. It was a historic moment for India, as all four team members secured awards— a first since the country began participating in the IOL in 2009. The journey to IOL starts with the Panini Linguistics Olympiad (PLO), the national qualifier in India. Open to middle and high school students, the PLO has two rounds. The first round is held in multiple cities, and top scorers move on to the Asia Pacific Linguistics Olympiad (APLO) and a linguistics camp hosted by IIITH in Hyderabad, where they are trained in problem-solving techniques. "For the last few years, IIITH has played a major role in mentoring India's IOL team," said Krishnamurthy, who also serves as the Organising Chair of the PLO Board and oversees the 10-day camp. The International Linguistics Olympiad, one of 13 International Science Olympiads, brings together secondary school students and linguistics experts. Participants are challenged to analyse grammar, structure, and the cultural history of languages, and to demonstrate their skills through complex puzzles and analytical tasks.
