Elon Musk was reportedly left "speechless" when Google DeepMind cofounder Demis Hassabis pointed out a basic flaw in Musk's plan to colonize Mars. The revelation, detailed in a New York Times report on OpenAI's history, occurred during a tour of SpaceX's headquarters in 2012. Musk, enthusiastic about his Mars colonization plans, was surprised when Hassabis suggested that if AI surpassed human intelligence, it could potentially follow humans to Mars and pose a threat. Musk, initially taken aback, later invested in DeepMind but eventually expressed concerns about the firm's AI capabilities, citing it as his "top concern" regarding artificial intelligence.
