Several videos have surfaced showing Elon Musk-owned Tesla's autonomous robot Optimus playing 'rock, paper, scissors' with people at an event to launch Tesla robotaxi 'Cybercab'. Optimus lost 3-0 against one man, who introduced himself as Emmanuel and also asked the robot to say 'hi' to his wife. "You're good at 'rock, paper, scissors'," Optimus was heard telling Emmanuel.
