All this seems to relate fine to nonorganic bodies, but what about an
uploaded mind in an organic body? You'd have to alter some parts of the
brain, namely those parts controlling bodily functions. Obviously if
your brain was running proportionally faster than your body, you'd
want your heart & breathing to remain normal.
I'm concerned as to how organic muscle would react to the greatly speeded-
up signals from an uploaded brain. If your brain is running, e.g., 100
times faster than your body, would your muscles be able to differentiate
signals it receives at 100 times its usual rate? What about muscle burnout
from being used at such a fast speed?
I think it would be better to go with an entirely non-organic (i.e. non-
biological) body. These would be simpler, more flexible, and assumedly
more durable & longer lasting. You can do so much more with a non-bio-
logical (I hesitate to use the word "robotic") body, and wouldn't be limited
by environmental factors such as in space or the ocean bottom.
Perhaps in a utility fog, one could even have polymorph abilities, a la
the D&D or nethack games.

My view of it is this: Why limit oneself to just one existence, be it only
in the "real" world or only in cyberspace? Best to have the best of both
worlds.
