  Doubly Special Relativity (DSR) is a theory with two observer-independent
scales, of velocity and mass, which is expected to replace Special Relativity
at ultra-high energies. 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?''
