We will first review the recent progress in SYK models and their global impacts in quantum gravity, QCD, condensed matter physics, quantum information science and deep machine learning. Then we will outline the results achieved in our recent works in [1-5]. This colloquium is pedagogical, so should be accessible to any graduate students who are interested in working on this still rapidly expanding direction and other related directions such as many body localization (MBL), eigenstate thermalization hypothesis (ETH), Neural networks/Deep Machine learning, Complexity, etc.
