    I expect optimized communicaton would tend to be indistinguishable from
    low-level noise to those who don't have the key. Also, in contrast to those
    who feel that advanced civilizations will continue to expand to take over
    ever increasing volumes of physical space, I suspect there's very little to
    be gained by moving a lot of mass around, and that advanced civilizations
    will tend to grow in complexity in ways that we are unlikely to be able to
    observe. I agree with Greg that detecting an extraterrestrial civilization
    is very unlikely due to the relatively short blip during which they would be
    emitting detectable signals.
