As I've mentioned before on this list, the coolest heat sink available
is not intergalactic space, but black holes. The implication is that
advanced civilizations should live near black holes. See

I would like to hear more about why you believe all advanced
civilizations will move out of evolutionary regimes. And also why, once
they do, they won't be able to find a way to ensure the friendliness of
their offspring. I asked this question about a year ago (see
http://www.extropy.org/exi-lists/archive/0205/106121.html), but you
never answered.
You mention the fact that the Europeans and the Japanese are having
falling fertility rates. Why is this happening? Is it an accident
unique to the human species that richer societies do less reproduction,
or can we expect the same of other intelligent beings?
