What makes the Grok medical promotion structurally different from ordinary tech hype is that the contradiction is internal. Musk positioned Grok as a tool that could give patients a meaningful second opinion on scans and lab work — and the chatbot, when queried directly, pushed back against that framing, warning that medical data uploads carried real risks. A product that disavows its own marketed use case is not a minor inconsistency; it is the company's own risk assessment showing up where the promotional copy should be.
