Abstract

These notes reflect the contents of a discussion session on higher-spin dS/CFT, which was led by the author as part of the Corfu Summer Institute 2021 workshop "Quantum Features in a de Sitter Universe". I present and motivate some basic outstanding questions within the subject, and offer tentative answers. The presentation is heavily biased by my own work, which emphasizes the importance of extracting physics inside observable regions of de Sitter space, i.e. inside cosmological horizons. One may compare & contrast with my earlier views, expressed in arXiv:1710.05682. Since the writing of that document, I've reversed my position on the finiteness of the Hilbert space dimension, and become disillusioned with elliptic de Sitter space $dS/\mathbb{Z}_2$ as a promising direction of study. These are replaced by a focus on scattering amplitudes in the static patch.
