And then there are the problems of forking (this comes up in Walkaway) and restoring to older versions to erase part of your life (which comes up in Down and Out in the Magic Kingdom, which Walkaway is a prequel for and which I have now read). *I'm* me, but is each of the dozen independent sims of me also me? And how much of a "restore" is me if there's been selective editing? Can you cherry-pick commits too?
