There might be as few as one intelligent civilization per galaxy

I think there's a good argument that there might be a very few of those. And actually there's a reasonable argument we might assume there's about one per galaxy on average, any one time, which means that we're it.

The universe appears to be a hologram where reality can be represented by information on 'the walls'

Everything that's going on in the room can be perfectly represented by a quantum theory that lives on the walls. So the universe appears to be in some sense, a hologram, right, it's called, it's got a fancy name. It's called the ADS CFT correspondence... you can characterize everything that's going on in a regional space, by a theory that just lives on the edge.

Information is never truly destroyed by a black hole and could theoretically be reconstructed

It seems now that's what happens in black holes. So you throw the book in, and then at some point in the distant future, you could collect all the Hawking radiation that comes off and reconstruct the book... if some sufficiently clever, super advanced civilization, if they could collect all the Hawking radiation and put it into some quantum computer would actually reconstruct you.
