Not necessarily. The level of technology that we're envisaging
should be easily capable of recreating a brain from the recorded
information. Not that I see that as being a very good option. There
will surely be better physical systems that could serve to embody an
upload. I'm thinking along the lines of utility fog brains and
bodies, but there will be other options too, I'd think.<br>

In fact, it might be very difficult to 'download' an upload into
their original biological brain, and possibly impossible, as you'd
have to convert all the upload's experiences as an upload into the
biological equivalent, and the original brain might not be capable
of holding those experiences without being changed a lot. It could
well be that shortly after being uploaded, people would change so
much that downloading again would be impractical, and creating a
new, synthetic brain/body would be the only practical solution.<br>
