Deep learning isn't living up to the hype, but still shows promise

A few years back I jumped on the "machine learning will eliminate the need for radiologists" bandwagon. In my failure, however, I'm joined by the biggest experts in deep learning, like Geoffrey Hinton, who in 2016 proclaimed it was "just completely obvious [that] within five years deep learning is going to do better" than trained radiologists. And as an industry, we all keep being wrong about how fast deep learning, a branch of machine learning, will progress. Or not really "progress," because deep learning is progressing, and quickly. What it's not doing, however, is progressing to the point that it's displacing people.
