World's richest man Elon Musk reacted to a video of his Chinese 'doppelganger' by tweeting, "Still don’t know if real or AI-generated." The video posted on Musk's platform X showed his doppelganger boxing with a person wearing a paper bag bearing Meta CEO Mark Zuckerberg's face. Earlier, Musk wished to meet his doppelganger, which many believe is a deepfake.
