Great post Hal. I disagree with this part. It is easy for me to
imagine that a very advanced civilization might manage to cross
interstellar distances of a few light years but not be able to
manage the 10K or so light years of emptiness between
the Milky Way and even the closer dwarf galaxies.
I could even imagine an advanced lifeform crossing interstellar
space near the galactic core only and deciding the stellar
burbs out here are just too sparse to make it worth the effort.
