Wei: AI won't replace radiologists soon; he shows no data

OpenAI researcher Jason Wei thinks AI won't replace radiologists soon, because AI's abilities are uneven and demand for reads is elastic; this is Wei's personal judgment, with no data attached. Wei writes that X-rays alone can diagnose at least a hundred conditions. AI will learn the common ones first, and rare conditions, with less data, will lag, so AI starts out as a triage tool. Wei also says doctors will order more scans as reads get cheaper. Radiologists might read only 20% of incoming cases while scan volume grows 5 times. If reads get 10 to 100 times cheaper, people might get 10 or 100 times as many scans. Wei cites Hinton's 2016 claim that deep learning would beat radiologists within five years. Wei says demand for radiologists is higher now than ever (Jason Wei, 2026-10-19). Our reading: whether scan volume actually rises as reads get cheaper is the point to watch, and Wei gives no data on it. How we checked →

Concept illustration on a mustard-yellow background: a large black opening quotation mark sits at the top centre above two side-by-side booths, each lettered RADIOLOGY on its back wall with a dark panel hanging from the top (narrow on the left, wide on the right), and in each booth a round-headed white figure sits on a black office chair, chin on hand, looking at a red tray holding a chest X-ray. The right booth has a longer desk that also holds a laptop showing a speech bubble, with arrows on either side pointing left to the red tray and right to a grey tray of stacked chest X-rays, next to a white sign on legs lettered AI TRIAGE, and at the bottom centre a dark silhouette of a person's head and shoulders, seen from behind, faces the booths.
