Given Elon Musk's first principles approach and firm determination, we predict Tesla's Optimus robot will begin transforming factory life in 2028/2029, subsequently changing home life."

Musk responded: "It will start changing the status quo in 2027, with visible impact by 2028, and significant effects by 2029."
