For the even more curious, a scale to think about from wikipedia[1]: In 2010, it was estimated that storing a yottabyte on terabyte-size hard drives would require one million city block size data-centers, as big as the states of Delaware and Rhode Island.
But this may not be a problem: either people have a soul or they don't.
- if they don't have a soul, then I don't see how cloning and killing could be a problem.
- if they do have a soul, then in the killing part the soul is detached from the destroyed body. And in the cloning part, some soul should attach to the created body.
The question is then whether the original soul reattach to the clone or another soul? It seems likely that the original soul reattach to the clone, because they are better atuned, than another soul.
Now, where you could have a problem, is if another soul get attached to the clone. Some episodes of ST TOS and of ST VOY explored the problem (soul splitting, interferences with souls from parallel universes, etc). But this doesn't seem to be the normal use case.
Of course, we won't know what happens in our universes until we try it. Go science!
