BREAKING: Grok saves a life. In late 2025, a 49-year-old man, pseudonymously known as "u/Tykjen" on Reddit, Norwegian—credits xAI’s Grok AI with saving his life after a near-fatal misdiagnosis. After 24 hours of severe abdominal pain, an ER visit resulted in antacids for presumed acid reflux. Unrelieved, he consulted Grok, which flagged a potential perforated ulcer or atypical appendicitis, urging a CT scan. Returning to the ER, the scan confirmed an inflamed, near-ruptured appendix, leading to emergency laparoscopic surgery and a full recovery.
