True... and actually one of the more optimistic points of view I hold is that science fiction/speculative fiction in some ways prepares us culturally for unexpected consequences of revolutionary technology.
Robots and AI's, for example--the idea of laws that govern interactions between them and humans, pervades development and discussion of new breakthroughs. Even if we don't strictly adopt the classic Asimov line, just having a general understanding of how much it matters improves our outlook.
"If fighting is sure to result in victory, then you must fight! Sun Tzu said that, and I'd say he knows a little bit more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor. Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat, and then he beat the crap out of every single one. And from that day forward any time a bunch of animals are together in one place it's called a zoo! (Beat) Unless it's a farm!"
