Well, that's certainly a more entertaining hypothesis than the opposite
one -- that our world may be the only, or among the first, to develop
A two-billion-year head start would be enough time for a signal from a
really bright (**really** bright) extraterrestrial radio station to have
here even from other galaxies -- say, from one of the sixteen galaxies
the Virgo Cluster (about 60,000,000 light years away).
So maybe SETI@home will tune in a repeating broadcast of "Singularity
Dummies" after all. In fact, I think the Virgo Cluster is in their
search area -- they have used it for position checking. See:
