Marc Andreessen has a bold new claim about your health. The billionaire investor says “Doctor ChatGPT” is already a better doctor than 99% of human ones. Doctors, and the peer-reviewed evidence, strongly disagree.
Andreessen made the remark on Joe Rogan’s podcast in early June. The New York Post clipped the line, and it spread fast after the prediction-market account Polymarket reshared it on X on 29 June. The number is striking. The backing for it is thin.
The claim
Andreessen offered no data for the 99% figure. He runs Andreessen Horowitz, one of the most powerful venture firms in tech, so the words carry weight. “99% of the time, the answer that I’m getting from the AI is better than I would get from talking to basically almost any expert,” he told Rogan. The Post turned that into the doctor line.
People are certainly trying it. OpenAI says more than 40 million people ask ChatGPT about their health every day. At that scale, even a small error rate means millions of risky answers, especially for patients who cannot afford a real visit.
