@clacke @hendric It had been a long time since I read any science-fiction, so I gave this short story a try, and I'm starting to understand why.
I'm not fascinated (anymore?) by techno-babble like "Ultimate Overdrive" and "paralyzers", tentacled beings or massive scales being hand-waved (like "Lords of the Universe" or extraterrestrial beings measuring time in "years"?). More generally, I was also frustrated by the descriptions which turned out to be very different in the author's mind than in mine, resulting in poor understanding of the implications of the characters' actions.
I was left with the feeling this text was both too childish and too clever for me, the worst possible outcome, probably. Thanks for sharing, though!
