Interesting. There is no easy way to tell whether you are right. The
maturation time of nanotechnology is certainly an important parameter
in predicting the future. There are two things I could take issue
with. (1) Will nanotech mature slowly? And (2), given slow
maturation, will that mean that a multipolar world order can remain
stable?
(1)
Why exactly do you think every stage will take thousands of
genius years? (I presume you mean good-scientists years?) Isn't the
design work fairly tractable (Drexler has already produced some nice
designs) and it is mainly the lack of molecular tools that prevent us
from starting building things? Better CAM would help a lot, and it is
on its way.
As you point out, each partial achievment would bring great benefits
to the power that makes it, so wouldn't this mean that it would have
a good chance of pushing further ahead, leaving the competition
behind?
If superinelligence (that could perform a thousand genius years in a
short time) comes before nanotech, or is developed at an early stage
of nanotech, then the bottle neck would almost certainly be the
hardware, the molecular tools, and in such a case the maturation
process would be almost instantaneous.
(2)
I believe the answer to the second question is No. I think there
would either be a negotiated merger, or the stronger power would
obliterate the weaker, and then immediately rebuild itself, and then
expand spherically at a good fraction of the light speed. A Yes
answer to (2) would presuppose that a negotiated merger isn't made,
and that neither power can know with a great probability that it is
strongest, or that the stronger power has some absolute ethical
prohibition from attacking its weaker rival.
