New Yorkers woke up Thursday morning to a giant blow-up figure of the world's richest person, one day before his already immense fortune is set to inflate thanks to the biggest IPO in history.The big bust of a shirtless and smiling Elon Musk appeared in Times Square overnight, adorned with harsh accusations about the SpaceX founder."SpaceX's Grok makes AI child porn," reads a giant tattoo plastered across the bust's upper abs and back.The message appeared to be a reference to accusations that Grok, Musk's xAI chatbot that was acquired by SpaceX earlier this year, produced sexual images of children.In response to complaints, Musk said in January that "anyone using Grok to make illegal content will suffer the same consequences as if they upload illegal content." The official X page also said its policy has "zero tolerance for any forms of child sexual exploitation."Grok's not-safe-for-work capabilities came up in SpaceX's S-1 filing last month, ahead of the rocket company's highly anticipated IPO, set for June 12. SpaceX warned potential investors that Grok's NSFW mode could pose "heightened risks" and "reputational harm," in part because it could generate "nonconsensual or exploitative imagery."The group behind the inflatable Musk is Safe AI Now (SAIN), which describes itself as a coalition of faith leaders, child-safety organizations, and other groups and individuals. SAIN told Business Insider the inflatable would be up until 7 p.m. ET on Thursday.
