Larry Page & Sergey Brin had the PageRank paper (the algorithm behind Google Search) rejected. A reviewer called it “disjointed.” Geoffrey Hinton's Dropout was rejected for being “too simple.” I often feel the academic peer review is like a random process, especially when a paper is very innovative and changes the paradigm; it often looks "wrong" to reviewers in the old paradigm.
