Even if we map every effect of every allele of every gene in the
human population, the fact is that those genes don't do anything
except _in the context of the environment in which they evolved_,
and we don't know nearly enough about what that environment must
contain for the process to be sustaining. What if there happens
to be some bacterium in the uterus that plays a vital role in fetal
development, but that can't survive in low gravity? Unlikely I'm
sure, but there are thousands of other little bits of Earth that
won't be taken with us, and while terrestrial life is robust, I
don't want to bet the farm on it.
Reproduction the old-fashioned way may be an old, inefficient and
haphazard technology; but it is a _proven_ technology. And some
of us still enjoy it.
