Elon Musk encouraged X users to upload medical images such as MRIs and CTs to train Grok, X’s AI chatbot, rekindling urgent questions about patient privacy, training data governance and institutional review. XAI says uploads will improve diagnosis capabilities; independent physicians and privacy experts warn of misdiagnosis risk and unclear consent frameworks. Universities and medical schools should track the development closely: faculty involved in medical AI research will face ethical-review challenges, potential HIPAA and data-protection issues, and heightened scrutiny of any collaborations that use consumer-provided clinical data. Research offices and IRBs will need clearer policies to govern third-party platforms training models on clinical images.
