Artificial intelligence was supposed to transform health care. It hasn't.

Artificial intelligence is spreading into health care, often as software or a computer program capable of learning from large amounts of data and making predictions to guide care or help patients. Investors see health care's future as inextricably linked with artificial intelligence. That's obvious from the cash pouring into AI-enabled digital health startups, including more than $3 billion in the first half of 2022 alone and nearly $10 billion in 2021, according to a Rock Health investment analysis commissioned by POLITICO. And no wonder, considering the bold predictions technologists have made. At a conference in 2016, Geoffrey Hinton, British cognitive psychologist and "godfather" of AI, said radiologists would soon go the way of typesetters and bank tellers: "People should stop training radiologists now. It's just completely obvious that, within five years, deep learning is going to do better."
