Tesla CEO Elon Musk said in an interview with CCTV Finance that every person could one day have a personal robot to care for elderly parents, watch over children, and serve as a one-on-one tutor. According to Odaily, Musk said one person could eventually control hundreds, thousands, or even tens of thousands of physical robots and digital agents. He predicted at least 1 billion humanoid robots within 10 years, possibly 10 billion within 15 years, and 100 billion within 20 years.
