My main crux regarding inter-civ selection effect is how fast will space colonization get. F.e. if it’s possible to produce small black holes, you can use them for an incredibly efficient propulsion and even just slightly grabby civs still spread at approximately the speed of light—roughly the same speed as extremely grabby civs. Maybe it’s also possible with fusion propulsion but I’m not sure—you’d need to ask astro nerds.
I haven’t thought about whether this should be the main crux but very good point! Magnus Vinding and I discuss this in this recent comment thread.
I guess the main hope is not that morality gives you a competitive edge (that’s unlikely) but rather that enough agents stumble on it anyway, f.e. realizing open/empty individualism is true, through philosophical reflection.
Yes. Related comment thread I find interesting here.
