The IUOC is not deleted in any way, upon the death of the physical body. The fragment that is the PMR you is not deleted either, it exists as information in the historic database, and can always be made active again.
You are in truth part of the IUOC, the part that has be 'partitioned' to agree by the PMR rule-set while engaged in this VR. If or when this partitioning is no longer useful, I imagine that the subset (us) will just re-merge with the IUOC's awareness, we (as in the PMR personality) are never a separate being from the IUOC to begin with, it's rather one whole being that can some smart tricks that enable one to be more useful.
There are a few threads here on the board that deals with this aspect,
Try this one for a starter :-)viewtopic.php?f=6&t=2834&p=4536
One post from the thread: It's straight to the point, and very useful.
Tom: OK, let me give you a more straight up model -- out of elementary school and into graduate school -- I hope this doesn't replace what you thought you understood with more confusion. If it does, forget I ever said it.
If you put the cowboy suit back on does the cowboy experience a great remembering? Of course not, the cowboy does not exist as a separate being -- it is just you pretending to be a cowboy.
There is no death -- just like the cowboy didn't die -- he was just virtual -- not real -- the physical isn't real, it is virtual. YOU are playing a data stream computer game that produces experience (the best teacher) and have just decided to change YOUR character's outfit (called a "meatsuit"). Nobody dies. YOUR character in the game is limited to work within the games rule-set. That character (you) is a projection of a copy of a portion of YOUR content, a part of YOU (the big YOU), a virtual characterization of YOU constrained by a rule-set -- a virtual alter ego -- working to become an alter no-ego. Little you is actually the big YOU in a constrained cowboy disguise, stop identifying with the little virtual you that doesn't really exist except as a virtual character in a computer game. YOU occasionally switch the virtual character's meatsuits to gain different experience and continue to play the game because YOU learn so much from it since the constraints of the rule-set simplify experience, interaction and feedback to a more effective level for learning. Nothing dies, your characters don't die, they are just virtual - virtual characters can't die, they are made up for the game, they are not real. Constraints come and go on a portion of YOUR content, that's all, and only during the coprocessing time share. YOU are real, not virtual, YOU are consciousness -- the sum of all YOUR virtual and non virtual experiences. YOU are using multiprocessing to send you (a portion of YOU) to a private school with rigid rules while YOU stay home and play computer games -- how sweet is that. You who are really YOU are identifying with the wrong you.
After all that, your mind is probably blown away and twice as confused. I don't put it this way very often because it is more that most people are conceptually prepared to deal with. Other models are warmer and fuzzier and make you feel more . well, real... and important... and special. Enough of this convoluted horsepucky -- Get real!
