Why humans learn faster than AI--for now

In 2013, DeepMind Technologies, then a little-known company, published a groundbreaking paper showing how a neural network could learn to play 1980s video games the way humans do--by looking at the screen. These networks then went on to thrash the best human players. A few months later, Google bought the company for $400 million. DeepMind has since gone on to apply deep learning in a range of situations, most famously to outperform humans in the ancient game of Go. But while this work is impressive, it highlights one of the significant limitations of deep learning.
