Does angular velocity produce relativistic time dilation effects? Would it be
possible to get your head and/or body to spin/orbit fast enough to time warp
into the future without the centrifugal force turning it to pulp?

Would continually supplanting a brain with, say fetus neurons, permit some sort
of biological uploading/augmentation, where the fresh neurons make up for/mimic
the ones that are dying off in the adult brain? The brain does appear to have
a fair bit of redundancy worked into its structure, so given some time to
integrate themselves with the old neurons, the new ones may be enough for a
transparent transition from one generation of neurons to the next.

Assuming we can engineer designer restriction enzymes/ligases with the ability
to cut and paste DNA segments with high specificity, and that a
distribution/communication system can be set up to apply these operations to
all of the cells in a body, implementing the newly found bug-fix/patch to some
disease should be straightforward. Eventually, this should lead to an
optimized and perhaps minimal genome which will allow standarized (platform
independent?) disease patches and/or body subsystem upgrades. This technology
should arrive much before nanotech, as much of the enzyme machinery is already
in place. Designing the genetic patches and predicting their side effects is,
of course, the hard part, but nanotech faces the same hurdle. Are
object-oriented protein languages & compilers far off?
