Ludd Was Right: Severely and harshly averted.  Low-tech societies aren’t even all that good at surviving the cataclysms of nature, much less the realities of galactic realpolitik, which, in its hotter moments, could accurately be summed up as “Hey, space is a tough place where wimps eat fiery plasma death!”.  Reject technology, get eaten by someone who didn’t.  The unfairness of this is essentially irrelevant in the face of the inevitability of this.
