Tesla CEO Elon Musk told an interview he expects personal humanoid robots to
handle eldercare, childcare, one‑on‑one tutoring and other jobs. He said one
person could control hundreds, thousands or even tens of thousands of physical
robots and digital agents. Musk predicted at least 1 bln humanoid robots within
10 years, around 10 bln within 15 years and possibly 100 bln within 20 years.
