In these notes we first discuss the postulates of DSR, and then turn to presenting arguments supporting the hypothesis that DSR can be regarded as a flat space, semiclassical limit of gravity. The notes are based on the talk presented at the conference ``Special Relativity -- Will it Survive the Next 100 Years?''26 pages, Submitted to Lecture Notes in PhysicsGeneral Relativity and Quantum Cosmologytext
