Ben Riley discovered a dangerous disconnect between his expertise on AI risks and his father's trust in the technology. While Ben writes about AI dangers through his newsletter Cognitive Resonance, Joe Riley, a retired neuroscientist, began relying on AI tools like Perplexity for medical decisions. The irony intensified when Ben learned his father was refusing potentially life-saving cancer treatment based on AI research over his doctor's recommendations.

Joe faces a double diagnosis of chronic lymphocytic leukemia and early-stage lung cancer. His oncologist at Fred Hutch Cancer Center recommended treatment that could extend his life by years, but Joe refused. The situation became critical when Ben discovered through medical records that his father had been delaying treatment against medical advice, instead following AI-generated research about his condition.

The case highlights growing concerns about AI's role in healthcare decisions. Perplexity, the AI tool Joe favored, markets itself as providing "answers you can actually trust," though The New York Times has sued the company for copyright infringement. This personal dilemma underscores the tension between technological trust and medical expertise as AI tools increasingly intersect with life-or-death healthcare decisions.
