At this very moment, I don't think there is that much need to solve this
problem. The technology to copy yourself is out of reach, isn't it?
Before that, we're facing another problem: what about simulated
consciousness. We kill most animals without really caring, but what about
killing a simulation of a human identity - simply switching the power off
and deleting the information?

We are all humans and believe that we all have consciousness, currently,
I don't see any way to prove this. I know that I am real, and that I have
a consciousness, but the whole world around may be just simulated
(maybe we've had nanotech milleniums ago, and my current 'experience' is
just an attempt to understand ancient biological organisms). It's
pointless to discuss this, but I think it illustrates the problem very well.

Even when you completely understand the brain, it's just like completely
understanding a computer. Does Eliza have a consciousness or not? If I
scan my brain, and have a simulation of my personality in a computer
(which will probably be easier than copying myself), does this simulation
have a right to 'live'? Even if I can't experience what this simulation
experiences, I'd still try to protect it because it could completely
replace me (maybe the computer is simply better), and then could be the
one who decides about what is done with me (the simulation also can't
prove that I have a consciousness).

That's something you could control: before duplicating yourself,
understand that after duplication, you can either be the real one, or the
duplicate - then, look at the place where you get scanned, and the place
where the copy is 'created'. After duplication, you have an easy way to
decide whether you're the original or the copy - but you will also know
that to the outside world, it doesn't make ANY difference. Of course, you
will remain in your body. You could consider your duplicate some sort of
'child' - only that from the first moment, it has your 'functionality'.

That's the major problem: the world will never find out that you were
actually blown out of existance.

YOU won't be dup2, but you can be sure that dup2 feels exactly the way
you do (at least for the first few moments).

That's quite an interesting thing: _I_ would probably go mad after
transportation, because my new instance couldn't deal with the fact that
I was wiped out. Someone who believes that it works (that the
consciousness is transported with the information), would feel fine (and
the original wouldn't care because it simply does not exist anymore).

The way uploading is described in the Extropian-FAQ seems possible, but
if that works, 'transporters' like in Star Trek will be completely
obsolete (you simply download a part of you to any place, then scan that
'instance' of you after it made some experiences, and by that expand your
consciousness - you won't be able to experience what your new instance
experiences first hand, unless you're connected in any way - but that
doesn't really matter... only if that instance gets destroyed before you
can access the new information)

This is the concept of 'soul' right? I do exist, but only because my
brain and body exist (the brain seems more important, but it will
probably be possible to simulate the body, so my 'consciousness' won't
even realize it).

I think this is the most relevant part. I think I do understand what you
mean by effing now, but I don't think it will help finding out where
'consciousness' is. This will be quite interesting, for example you'll be
able to experience things exactly like other people, maybe even computers
- but it's still YOU who makes this experience, and it won't help you
prove another consciousness. It will also not help transferring your
consciousness. Mind merging could be possible, though.

I don't think so. By certain substances, you can alter the chemistry in
your brain, which also changes your consciousness temporarily. If you
know how extreme some of these substances are, this gives you a vague
idea what 'uploading' means, I guess (it's even more different... a LOT
more different).

I don't think this really helps (at least it doesn't make it clear to me)

I wish one could finally prove 'soul' - that would make it SO much
easier! If 'soul' was a not yet discovered energy, you could look
for ways to redirect that energy. Unfortunately, this does not seem to be
'real'...

sorry for the long posting, I hope it showed some new aspects...
