GANs Demystified -- What the hell do they learn?

This article is a summary of the research paper "GAN Dissection: Visualising And Understanding Generative Adversarial Networks". The paper provides an excellent insight into the internal representation of GANs and gives a close answer to the following question. What the hell do GANs learn? We've all seen stunning results produced by GANs, almost indistinguishable from human work in some cases. But how they represent learned knowledge is still a mystery.
