Agreed. I wasn't referring to the brain copy at this point. I was trying
to dispute the idea that we could build duplicate rooms so exact that coin
flips and die tosses always come up the same for both duplicates in separate
rooms. I doubt we could maintain such duplicate environments for long. I
think copying the brain structures are much easier.

I agree here too. In fact, I personally do not require a surviving version
of myself to be very similar to my current self at all. I participate in
these thought experiments for fun, but I doubt they will ever have an impact
on my actual upload choices in the future.

The first two pose no problems for me since they seem to add functionality
to my one and only consciousness. The third possibility creates a better
version of me, but leaves the original me still suffering under its original
design flaws.
