What's in the Tent of Machine Learning?

Before photography, the representation of a battle was some painter who was told what happened on the battle and painted a heroic image. Matthew Grady took pictures of the battlefield at Antietam with bloated bodies lying in ditches. And now we're talking about things that are at least as dramatic and different and interesting. It's not even that deep learning doesn't exist anymore; it's really imbued in all these other things.
