Elon Musk predicts Tesla's Optimus robot will be a force for economic good — even if it ultimately eliminates much of the need for human labor.

While the humanoid robots are a production challenge and aren't launching anytime soon, Tesla has demoed them handing out candy on Halloween, performing Kung Fu with Jared Leto, and dancing onstage at its recent shareholder meeting.

But Musk says he has an even bigger vision for the robots; he wants them to transform the economy.

"People often talk about eliminating poverty, giving everyone amazing medical care," Musk said at the Thursday shareholder event. "There's actually only one way to do that, and that's with the Optimus robot."

Musk later doubled down: "Optimus will actually eliminate poverty."
