OK. If we define the start of modern civilization in terms of the use of
fossil fuels, then we have been at it for only about 200 - 250 years. Prior to
that, human beings had a civilization built upon "renewable" energy -- things
like slavery, the canonical form of renewable energy. That kind of
civilization started about 7 or 8 thousand years ago, dating from the
development of agriculture in what today is Iraq.
Bottom line, ten thousand or so years of energy from breeder reactors would be
a long, long time compared to prior industrial sources of energy -- and would
provide our descendants with a lot of time to develop whatever technology they
would need after that.
