I think you're misinterpreting the analogy. The DNA is not the actual
hardware which performs the computations for intelligence. Rather, it
is a blueprint for a hardware which can perform the necessary
computations and which has a certain but limited pre-programming.
The accurate analogy would be that we could produce a blueprint for
an intelligent machine with current technology. Actually making
the object the blueprint describes, however, is a different problem.
If we can't test the blueprint, of course, we will be hard-pressed
to decide whether the blueprint we make is valid.
Incidentally, about 50% of our DNA is involved with the brain, so
10% may be low. Naturally shifting from 30 megs to 150 megs makes
no qualitative difference to your argument.
