"Pleased to meet you! Soooo... how is YOUR originating species doing?..."

That actually seems like an extremely reasonable question for the first interstellar meeting of superhuman AIs.

I disagree with EY on this one (I rarely do). I don't think it's so likely as to ensure rationally acting Friendly, but I do think that the possibility of encountering an equally powerful AI, and one with a headstart on resource acquisition, shouldn't be dismissed by a rational actor.
