I remember this paper being discussed in the novel "Science of Discworld" -- a super interesting book involving collaboration between a fiction author and some real world scientists -- where the fictional characters in the novel discover our universe and its rules ... I always thought there was some deep insight to be had about the universe within this paper. Now moreso I think the unexpectedness says something instead about the nature of engineering and control and human mechanisms for understanding these sorts of systems ... -- sort of by definition human engineering relies on linearized approximations to characterize the effects being manipulated -- so something which operates in modes far outside those models is basically inscrutable. I think that's kind of expected but the results still provoke the fascination to ponder the solutions super human engineering methods might yet find with the modern technical substrates.
