Here is another article that appeared today, reviewing some of the lessons that I think the information paradox teaches us about broader aspects of quantum gravity. https://arxiv.org/pdf/2012.05770.pdf
I started this article with the plan of writing up some of the discussions we had at the summer conferences. But then I realized that there were many ideas that people were talking about that were not explained clearly in any one place. So I kept writing … and kept writing … and when I finished, I found that I was at 156 pages :D As they say, in runner’s parlance, that’s a PB.
But I tried my best to write a coherent story about an old subject; to emphasize the main physical ideas with as few technicalities as possible and provide the background material necessary to understand these ideas. In fact the only parts that are somewhat technical are about issues that are conceptually well understood.
So although the article is long, I hope that it will still be fun to read, and useful.
And send me comments if you have any.
