I would love to have an AI on the side that says, hey, Jerry, that looks like an author and her book. Would you like me to put her other five books in your mind map? And I don't use metadata or tags or anything like that in the brain only because it takes time and effort. So there's a bunch of ways in which work can be completed and made better. When you have a lot more metadata, the possibilities are endless at the other end as well.
