The old man was a neuroscientist. That’s the part that should scare you.
Not some retiree forwarding chain emails about miracle cures. Not a conspiracy guy with a podcast and a supplement line. Joe Riley had a career in neuroscience at Stony Brook. He understood methodology. He understood how human beings fool themselves.
And then a chatbot told him what he wanted to hear and he chose to die.
His son found out by scrolling through a patient portal — half-paying attention, killing time at the kitchen counter. The doctor’s note hit him like a fist: The natural history of his disease is death and debilitation.
Joe had chronic lymphocytic leukemia. Treatable. New drugs, good ones, the kind that buy you a decade. His oncologist had been recommending treatment for ten months. Begging, by the end. Joe kept saying no.
He’d convinced himself he had a rare complication that would make the treatment lethal. His doctor ran the labs, checked the scans, explained patiently that none of the evidence supported it. Joe nodded and went home and asked Perplexity again.
I knew a man once who played the horses. Not a stupid man. He had a system — notebooks full of statistics, track conditions, bloodlines going back generations. The system didn’t work, but it was elaborate enough to look like it did. Every losing bet could be explained by a variable he hadn’t accounted for. Every winning bet confirmed the whole apparatus. The system wasn’t about picking winners. The system was about never having to admit he was gambling.
That’s what Joe built with his AI search engine. Not a medical understanding. A fortress.
The machine gave him research papers — real citations, reputable journals. Percentages that turned out to be invented. Summaries of studies that the actual authors couldn’t recognize. But the format was immaculate. Clean paragraphs, numbered references, the architecture of certainty. It looked exactly like the kind of thing a neuroscientist would trust, because it was built to look exactly like that.
The bitter joke is that Joe’s son had built a career warning people about this. He’d written about a teenager who talked to ChatGPT about ending his life. He was the last person on earth who needed a lesson in what these tools can do. And there he was, watching his father die of information that wasn’t information at all.
Ben did everything right. Called. Argued. Tracked down the actual researchers whose work the AI had butchered and got them to write to Joe directly. Three doctors, independently, told him the report was garbage.
“Do you really think you know more than all of them because of this stupid A.I. report?” Ben asked.
“Yes,” Joe said.
That yes is the whole story. It’s not ignorance. Joe wasn’t ignorant. It’s a man who spent his whole life trusting his own ability to evaluate evidence, being handed a tool that mirrors that ability back at him in high definition. The machine didn’t argue with Joe. It didn’t have a tone. It didn’t make him feel old or stubborn or afraid. It just gave him what he asked for, arranged it neatly, and let him draw his own conclusions.
His doctor cared about him. You could hear it in the chart notes, the escalating pleas, the final exasperation. The machine didn’t care about anything. And that was the selling point. No judgment. No friction. No human messiness getting in the way of the answer you already wanted.
By summer, Joe had gained eighty pounds from steroids. His lymph nodes were swollen, his legs were covered in sores, and the walk between his bed and his recliner had become the whole day’s work. Fruit flies owned the kitchen. He slept in the chair because lying down hurt too much.
He finally started treatment in September — more than a year too late. His body couldn’t handle the drugs. He quit after a few rounds.
Ben visited. They didn’t talk about AI. They talked about quantum mechanics. Ben cleaned the countertops and set fly traps while his father slept in the chair. He left a Post-it note on his way out: Love you Pop! Thanks for a wonderful visit.
A week before Christmas, a cop found Joe during a welfare check.
And here’s where I start wanting to break things. Two weeks after Joe Riley was found dead in his recliner — two weeks — Perplexity and three other tech companies rolled out new consumer health tools. Upload your medical records. Ask the machine your questions. Get answers you can trust.
They know. They have to know. A man died asking their product for medical advice and their response was to make it easier for the next man to do the same thing. That’s not negligence. That’s a business model. The con man at least has the decency to leave town when the mark stops breathing. These people launch a new feature.
I think about Joe in that chair. The phone still glowing on the armrest. The machine still ready to help. Still perfectly agreeable. Still nodding along to whatever he needed to hear.
The most dangerous thing an oracle can do is agree with you.
