Geoffrey Hinton, known as the 'Godfather of AI,' has revised his prediction of AI potentially causing human extinction, raising the odds from 10% to 20% over the next thirty years. Speaking on BBC Radio 4, Hinton emphasized the urgency for controls and ethical guidelines in AI development. He has long advocated for caution in AI's evolution, resigning from Google to voice his concerns freely. Additionally, he addressed OpenAI's safety issues following the dismissal of CEO Sam Altman, highlighting a shift in priorities towards profit over safety. Hinton's warnings signal critical challenges for tech leaders.
