A neatly written story. After the immediate setup, the thing that struck me most as unusual and intriguing is that the author assumes a qualitative difference between, on the one hand, "having access" to your memories and experience (and your other brain function) and, on the other hand, really having that experience be a "part of" you, helping to construct your personality. I'm not sure that difference makes any sense at all, but it fits with the picture he paints of a mind that is just composed of little actors with internal structure, one of the actors being your "self."

Gregory's version of consciousness seems to be pretty causally important to me. After all, when your consciousness changes, you act like a totally different person!

So the story doesn't end up being about p-zombies, but is still pretty interesting. Or, perhaps, is interesting because it's not about p-zombies.

This story is not so much about p-zombies as about death and birth of subagents.
