I'm preparing a talk about the black hole information loss paradox. As I was thinking about a good way to summarize the vast number of attempts that have been made to address the issue, I thought a diagram would be helpful, and here is what I came up with. It's essentially a summary of the list in this earlier post. The red bars indicate the challenges one has to face in each case.
Do you find this diagram helpful, or is it more confusing? Have I forgotten something important?
Update: I've fixed a bug, thanks to Foresme's comment.
