One thing that's endemic is creating copies is free. I wrote a speculative essay called an Infinite Room for Thought and it occurs to me that one of the things that is unique to a digital space is I can have the same book open to different places in different work areas in the room. This is, effectively, the idea of transclusion made practical.
It's the same book, but I'm using it in different contexts. The same note files, opened simultaneously in different views.
Seems like we've entangled the view and the data in many of our current computing systems. By freeing the data to interop across systems and be accessible, we can create many different views and clients (thinking of Geoffrey Litt's bring-your-own-client) for the same pieces of data.
