Deep Learning Is Hitting a Wall

Few fields have been more filled with hype and bravado than artificial intelligence. It has flitted from fad to fad decade by decade, always promising the moon, and only occasionally delivering.

"Let me start by saying a few things that seem obvious," Geoffrey Hinton, "Godfather" of deep learning, and one of the most celebrated scientists of our time, told a leading AI conference in Toronto in 2016. "If you work as a radiologist, you're like the coyote that's already over the edge of the cliff but hasn't looked down." Deep learning is so well-suited to reading images from MRIs and CT scans, he reasoned, that people should "stop training radiologists now" and that it's "just completely obvious within five years deep learning is going to do better."

Fast forward to 2022, and not a single radiologist has been replaced. Rather, the consensus view nowadays is that machine learning for radiology is harder than it looks; at least for now, humans and machines complement each other's strengths.
