Review paper on de Sitter and Holography

A review paper on de Sitter and holography that I have been collaborating on with Aayush Verma has been completed. While this is a preliminary version and we may not arXiv it immediately (perhaps after some more refinements), the present state of the paper justifies to an extent the title. It is based on discussions on the general aspects of de Sitter, holographic entanglement entropy from usual dS/CFT and bit threads, the recent works by Suvrat et al on the Hilbert space of de Sitter quantum gravity, the work on algebra of observables in de Sitter space by Chandrasekharan, Longo, Pennington and Witten, some brief aspects of Cauchy slice holography by Wall et al, and finally a mention of bulk reconstruction in the sense of dS/CFT. In upcoming revisions, we will elaborate on some aspects and include further works, such as cosmic ER=EPR by Cotler and Strominger, dS/dS, and Balasubramaniam et al's works on de Sitter space.
