Elon Musk: Over 1 billion humanoid robots within 10 years, possibly reaching 100 billion in 20 years Elon Musk shared in an exclusive interview with CCTV Finance that in the future, one person could simultaneously control hundreds, thousands, or even tens of thousands of robots and digital intelligent entities. He provided specific predictions: within 10 years, the number of humanoid robots will reach at least 1 billion, 10 billion in 15 years, and 100 billion in 20 years. Musk outlined the specific uses for these robots: caring for elderly parents, babysitting children, and serving as one-on-one personal tutors. Currently, Tesla's Optimus is still in the small-scale production phase and has yet to achieve large-scale commercial application, with a significant gap between production capacity and these forecasted figures.
