Aldous Huxley wrote Brave New World Revisited in the 1960s (I think) because, he said, when he wrote BNW he thought there would be a fairly long period of techno-utopia and human flourishing before the techno-autocracies developed, but he came to believe they would come concurrently.
Tech like this makes me think of that. Green-energy autonomous machines that can take away the drudgery of human toil. Yay!!! Corpse-fueled autonomous machines that can be deployed on the battlefield in long wars of attrition. Boo!!!
Of course, same with nuclear power. Same with fire I suppose if we want to take it all the way back.
