This is not a real article, just an announcement: under the article
Nima Arkani-Hamed, a co-author of the paper and arguably the leader of current particle physics, gives a rather detailed explanation of his viewpoints and the really attractive features of these models. So I hope that this answer of him will increase the number of visitors in interested in physics, and it will double their average IQ! :-)
Also, Jacques Distler describes the article about the predictive landscapes here.
