AI diagnosing disease better than any one doctor can. If we could build a model with a normalized dataset of everyone's medical history, we could catch a lot of diseases early. Especially if we encourage people to report even minor symptoms when they have it.

Imagine for example that everyone who gets diagnosed with pancreatic cancer reported repeated congestion of the left nostril three years before diagnosis. It's unlikely any doctor would ever make that connection, but an AI could, and then suggest regular pancreatic cancer screening to people reporting frequent left nostril congestion.
