description <!--HTML-->I will begin by reviewing some of the challenges one encounters when trying to make sense of quantum gravity in the presence of a positive vacuum energy density. In particular string theory in its present form appears inadequate to settle even basic existence questions. To resolve these issues, a more fundamental, possibly holographic, quantitatively precise framework will likely be needed. I will discuss some recent progress in this direction.
