Maybe this is captured in “Infinite Detail” but it seems to me that this list is missing the one thing that is explicitly stated to be the key to making the MetaVerse popular in the book: highly detailed and accurate facial expressions. The facial scanner in the movie adaptation of Ready Player One was a good touch for this. I think we could accomplish the same with temporary (or permanent!) non visible tattoos for facial tracking via cameras.
