Meta's billionaire CEO Mark Zuckerberg took to Instagram to share a video of him training with MMA fighter Khai Wu ahead of the 27-year-old's UFC Fight Pass debut. Conor McGregor reacted saying, "Yo!!! F****** awesome Mark!", while a creator asked, "Can I unlock these skills in metaverse?" Another user wrote, "[Wu] does not wanna hit Zuck and lose his account."
