Witten discusses this in . The problem seems to be that a holographic quantum description is impossible in de Sitter space, because it lacks the correct kind of asymtopia to put the holographic data on. On can perhaps avoid this problem by making the counterfactual assumption that the universe is really AdS, and we live in a metastable dS bubble inside the AdS universe.
