Elon Musk is placing a bet on robots. It could be a long time coming

Washington, DC (CNN)Tesla CEO Elon Musk said Wednesday that he believes the company's goal of a humanoid robot is the most important thing it's working on. The electric vehicle manufacturer first announced its robot plans at its AI Day last year. Instead of showing off any sort of prototype, a person in a robot suit walked stiffly on stage and proceeded to dance, spin and pretend to jump rope. "Obviously that was not real," Musk told the audience, after thanking the person for their robot performance. On the company's earnings call Wednesday, Musk said of its planned robot, "This I think has the potential to be more significant than the vehicle business over time."
