I will give an informal review of some of the recent developments on reproducing the page curve in semi-classical gravity. I will then compare and contrast these results to older results from the study of holographic 2d CFT with sparse spectra and large central charge. In these quantum systems, there is a natural understanding of the CFT duals of the bulk semiclassical classical saddles that are responsible for evading information loss. I will end with some cautionary remarks explaining why I believe it is too early to declare the information problem "solved". For Zoom link please contact damian.galante at kcl.ac.uk
