Like so much else in the TESCREAL crowd, they cannot imagine that aliens/transcended minds would not be venal and petty and extractive like they are
Their projection and short-sighted view means they are firmly planted in the Defect corner of the Prisoner's Dilemma
…they don't know it's iterated
…they can't imagine anything smarter than themselves
…therefore any super-intelligence must be rapacious imperialists like they are
