We are all very comfortable with the concept of backing up the
software on our computers and considering it as a totally separate
entity to the hardware. We can then, in the event of a hardware crash,
restore that software to new hardware and perhaps better hardware, and
carry on as if nothing happened.
This concept could also be applied to the data stored in the computer
hardware called the brain, all our consciousness really consists of is
the data stored, plus data accessed through our senses, processed in
the biological computer called the brain.
It is therefore a natural logical progression to believe that some time in the
future, given the advances being made in these fields, that our
human "software" could be "backed up" and then "restored" to
another biological brain or quantum computer, in the event of the
death of our bodies. To be later restored, including continued awareness and memories to a cloned body.
Because they are all scientifically possible these technologies, and other related technologies are currently being worked on. And if it can happen, logically it ultimately will happen.
That being the case, and if we are spiritual beings as theists claim,
what happens to the soul? Is it transferred with our "software" or
does it remain within the rotting hardware ? Does it go to God and
leave the "new" cloned you soulless? If the soul is transferred with
the "software" and if you then create multiple clones of your new body and
download copies of your "software" into each, does each have a
separate soul, or if there is only one soul are the others soulless
versions of you? Or does the soul and therefor God not exist?
