apologies for the delay in replying. My email notification got lost in a blizzard of trivia!

But if I know that everything that matters to me (in the context of "being" me) is going to survive my organic death, then my fear of death is dramatically reduced from the natural dread all mortals must occasionally feel to the moderate apprehension I feel on a trip to the dentist.

How do you imagine this conversation will be continued in, say, 80 years time, when both you and I have shed our mortal coils and are now revelling in our new digital existences - and we can both remember taking part in this original conversation. Do you imagine that you'll be arguing then that you are not the same person who penned those words? |

greetings squeak.
You've made some extremely pertinent points above and are, imho, definitely asking the right questions. I particularly like the analogy(brain in stomach etc) and would draw people's attention to experiments like this one, in which we can make people believe that they're perceiving themselves from outside their own bodies; experiments which dramatically illustrate your point.

I wasn't; I was speaking of the subjective, virtual experience our consciousness creates for us due to how it the brain works. | ah - our "self centred worldmap"
| squeak wrote: | | Even our organic brain swaps out cells over the course of its lifetime. What matters is that the matrix of processing itself remains in the same configuration down to whatever resolution consciousness requires. | precisely.
And this:
| squeak wrote: | | Purely as a thought experiment, what if for instance, if you "die", meaning the processing of your brain truly stops, and the matrix of your consciousness restarts, the exact matrix, and you "wake up" only to find yourself in a different physical location? (Such as a distributed consciousness in a digital substrate.) If the exact moment you are reawakened is calculated to precisely simulate your last moment of processing elsewhere, down to whatever required resolution, just where are "you" at anyway? It could be that a "clone" is only created if one matrix of your consciousness is still operating when another is started in parallel. Again, I'm speaking of the virtual experience of awareness. | ...is the crux of the matter.
| squeak wrote: | We'll have to consider that in a digital system, it can actually be switched "off", really off, as in stone cold with no power (thus no "life in the individual cells) and turned back on. Does the AI "die" when that happens? Or does personal consciousness not depend on the continual operation of a piece of hardware? What if the AI's data is, while it is shut off, copied entirely to another part of the network, the original erased, and the AI started up again? Does it experience true personal continuation?
If an AI experiences true continuation while existing within the different rules of a digital substrate, what does that suggest about human consciousness? | Exactly.
| squeak wrote: | | Some of these questions are ones we cannot actually answer, or even reasonably conjecture with certainty, until we're actually there and testing it out for real. | and that just about nails it! I think it is at least clear that those of us discussing the prospect this early in its history are, at the very least, going to be "early adopters". Let's hope we get to try it out and answer these questions definitively! |

@Harry:
Thanks for the comments.
I do think, based on what we know at the moment, that a method of mind transcription involving a direct connection to the physical brain where functions are handed off one at a time to an external network has a chance of being the most "reassuring" method of personal continuance for most people.
One scenario for testing this process might, in time, come about from experiments with volunteers who have suffered physical brain damage and retain enough sound judgment to understand the risks. The damaged parts of their brains could be gradually supplemented with artificial components, and so forth. This might provide insight on how the mind exists within networked hardware. (Be that hardware organic or inorganic.)
Edit: I hit enter too soon! There was a bit more.
Another thought experiment struck me regarding the need for the brain to be "always on" or not.
The classic Star Trek question of "do people die in the Transporter" takes on a new spin if consciousness can lay dormant in the brain without destroying one's authentic personal continuity.
Let's consider for a moment that the Transporter is disassembling the traveler's molecules, moving them, and then reassembling them in a new place. In fact, by some authors' descriptions, the Transporter doesn't even do that. It merely reads the /pattern/ of a person's molecular structure and at the other end, "generic" molecules fall into place in the pattern.
If the human brain doesn't need to be in constant operation for "you" to survive, then despite the fact that the molecules have magically (with science!) jumped from one location to another, the traveler is still alive.
What's more interesting though, would be the idea that if the mind cares not for arbitrary molecular displacement, then what does it care for the nature of the displacement? Teleportation or physical death result in the same scattering of atoms. What matters is that they get reassembled at some point. And if the mind is depending not on a particular physical atom for its operation but only the pattern the mind is running on, then authentic resurrection of the dead might indeed be possible. (Authentic, as in the uninterrupted continuation of the original person's existence, and not an omortal "clone" however flawless the duplicate copy of the person is.)
I'm interested in questions like this because they challenge us to think outside the framework we're "built" to think in. It might seem counter-intuitive to visualize whatever it is that really counts as our personal sense of self being totally independent of the particular atoms our brain is made of, because a lot of traditional human thinking has had to come up with so-called supernatural explanations to support that idea. The stereotypical image of the "spirit", and so forth.
Ironically, the truth might be /far weirder/ than any past religion's idea of the afterlife or souls. _________________ We're from Outer Space, every one of us! |

I'm particularly interested in the multiple strands of development which are aimed at allowing the most severely disabled to regain some control of their lives with neural implants. Some aim at allowing paralysed people to control prostheses while others "merely" provide the otherwise incommunicado with a new channel of communication. Parallel developments in our ability to map the physical processes involved in actual thought processing are also obviously leading in the same direction.
None of these developments has omortality in their sights. Indeed I suspect if you asked any of the scientists and technicians working on these projects for their views on the omortality hypothesis they would dismiss it scornfully. But check back in ten years time and I'll be surprised (and disappointed) if the prospect of digital mind capture hasn't become at least a talking point in the field, if not quite mainstream.
Ten years beyond that and we'll be seeing the first working models.

| very close to the model I expect. The "Quantum Transceivers" will merely transmit information (instantaneously of course, none of this restricted to light speed nonsense!) and at the receiving end, if the information is the physical description of an organic object (be it person or potato) a nanocloud at the receiver will assemble a clone. The nanocloud at the transmitter will reclaim its components to the local "pool". Note that this does impose two limitations on the "beam me up Scotty" scenario. We will only be able to send and receive to locations where we have prepositioned the transceivers. No random transmissions to places we've never been before. So the first visit to foreign shores will always have to be something physical (the transceiver) before "we" can step through it's portal.
And we'll never put organic material through the transceiver, because it really will kill the organic object being "sent". So the Star Trek scenario actually implies that they are already nano cloud based clones. Which really screws up their story lines. You can't kill a nano cloud!
