One hopes that immortalization will bring with it both much greater wisdom and more of a sense of civilization being one happy family. So the idea of mine that a rapidly expanding civilization could develop internal hostilities leading to civil warfare is perhaps unrealistic--still we don't know for sure. I can see various possibilities. One could be that it will become clear to advanced, former humans that benevolence is the only sensible attitude. (Actually I am optimistic that that will be the case.) If it is clear *enough*, however, such beings could conclude that there is essentially no danger from any other civilizations that may exist or come into being, so no reason to rapidly occupy every reachable niche in space. (Instead they may focus more on some version of "inner space" as has been suggested.) That is only one possibility, though. At the other extreme, you could have rapid colonization *and* precautions to prevent any other intelligent life emerging anywhere, to minimize any possible threat. (Perhaps the advanced beings will realize that benevolence is not to be taken for granted after all.) I for one hope that never happens, of course; I'd like to see ETs if I could, though I think they will be hard to find. Anyway, it's clear that there is much we don't know about all this, and firm conclusions about the likely behavior of advanced civilizations are hazardous. By the way, I'm looking forward to *Tales of Skastowe*. (I also will have more to say about other points in this posting.)
