  We are at a stage in our evolution where we do not yet know if we will ever
communicate with intelligent beings that have evolved on other planets, yet we
are intelligent and curious enough to wonder about this. We find ourselves
wondering about this at the very beginning of a long era in which stellar
luminosity warms many planets, and by our best models, continues to provide
equally good opportunities for intelligent life to evolve. By simple Bayesian
reasoning, if, as we believe, intelligent life forms have the same propensity
to evolve later on other planets as we had to evolve on ours, it follows that
they will likely not pass through a similar wondering stage in their evolution.
This suggests that the future holds some kind of interstellar communication
that will serve to inform newly evolved intelligent life forms that they are
not alone before they become curious.
