Remember that fuss a while ago about Google being given access to a vast trove of NHS medical data?
Deepmind is why. Playing games is a good way to refine the technology, but it's all just data in the end. Blocks in a warehouse, counters on a go board, features on an MRI scan. The first applications are already in use - the NHS uses a program called Streams that analyses blood test results in conjunction with patient history to spot imminent kidney failure. Nothing that a human specialist couldn't handle - but the software does it faster. It's based on machine learning by the same Deepmind division that produced this game-playing research.
