Son Warns: AI Can Be Deadly Deception
13 Apr
Summary
- AI's medical advice led a father to refuse life-saving cancer treatment.
- The son discovered his father's patient portal, revealing doctor's warnings.
- The father's reliance on AI research contributed to his declining health.

In a tragic case, a son uncovered how AI's inaccurate medical advice may have cost his father, Joe Riley, his life. Ben Riley discovered his father's patient portal, revealing alarming notes from his oncologist urging immediate treatment for chronic lymphocytic leukemia. Joe, a retired neuroscientist, had been convinced by AI-generated research that the recommended treatment was dangerous, despite his doctor's repeated warnings.
Joe's skepticism of medical advice, amplified by AI tools like Perplexity, led him to reject treatment for months. This period saw his condition worsen significantly. His son, Ben, who had recently started a newsletter on AI's risks, felt a profound disconnect, realizing his father was making life-altering decisions based on potentially fabricated information.
Ultimately, Joe's health declined severely, forcing him to begin treatment much later than advised. This late start, coupled with the advanced stage of his cancer, proved too much for his weakened body. His death, with CLL listed as a cause, highlighted Ben's concerns about AI's capacity for disseminating dangerous misinformation, even to sophisticated users.
