On December 6, Musk reacted to a post describing that a Norwegian man claimed that Grok saved his life. In the post, the user stated that the 49-year-old was misdiagnosed with acid reflux and sent back home.However, when the man shared the symptoms with the AI chatbot, it suggested a CT scan and suspected "perforated ulcer or atypical appendicitis." When the man went for a diagnosis, his appendix was found to be inflamed and was reportedly on the verge of rupture. The man underwent surgery.Elon Musk reacted to the post, writing, "cool." The news went viral on X. Later in the day, the SpaceX founder found it worth sharing more.

On December 4, a user, u/Tykjen, shared his experience of how xAI's chatbot saved his life."I’m alive and healed because an AI recognized the pattern when the first exam missed it, and because I had the exact words to make them take me seriously the second time. If you’re reading this while curled up in pain, googling symptoms at 3 a.m., and someone already sent you home once, please don’t wait," the user wrote in his Reddit discussion.The man also shared a video on social media after his story went massively viral. In the video, the Norwegian man could be seen thanking people for their overwhelming support. He noted that Grok recommended him not to share his story."But I had to share the story, because if I can help anyone else, I have to," he added.Elon Musk recently unveiled Grokipedia as an alternative to WikipediaElon Musk @elonmuskLINKis fully open source, so anyone can use it for anything at no costThe xAI founder has long been a vocal critic of Wikipedia, accusing it of bias.
