Perhaps the greatest evil for which the world has Science Fiction, one author and a nearly invisible editor to thank is "cyber bullying". Long before most people could even hazard a guess at what "cyber" meant. Before people had screennames, and instant messengers, and email. Before the world wide web was all that wide, or a world of its own a man created a way of reaching out and hurting ones enemies in a way that few would realize the would be the new wedgie, His proxy a boy called Ender (a use name) humiliated his opponent in a way that let him cause trouble and get away with it. Today we write new laws to deal with the technology that enables this crime, and continue to handwring at the crime itself. Orson Scott Card has much to answer for.
Death Shouldn't Find Me!
This is a trope that abounds in both Science Fiction and Fantasy. I can't blame either genre for creating it, just for perpetuating it. Raymond E Feist should shoulder his share of this simply for the early Midkemia books. Not only is the book littered with glamorous, graceful and ageless Elves two of the main characters from Magician become effectively immortal. Pug and Thomas go from keep rascals to not just towering heros, but unaging towering heros. Truly unfair.
Science fiction can't leave not dying alone either. In science fiction not only have anti-aging techniques like Weber's attempts to drive the entire future of mankind nuts by extending both puberty and menopause with his prolong treatment. Honestly, this one should really be considered cruel and unusual punishment. I can't honestly imagine people developing healthily mentally when they spend from eleven to thirty-nine looking unfinished, gangling and wondering when people are gonna stop calling them the Honorverse equivalent of "pizza face".
Lois Bujold is not without blame for perpetuating this bit of cultural denial. She's invented two totally different ways of not aging like a normal human. Her Betans (almost all of whom seem to be like 'the good kids" in A Brave New World) simply don't age. They don't age because they just live right, and their doctors have a pill for that. Simply disgusting. Not to out do this she has tweaked an entire twelve planet society with the use of trickle down genetics. They are smart, beautiful, healthy, resistant to poisons and yup, long lived. Utterly vulgar.
Then of course there are the weapons of play war where people almost play for keeps. Stunner, cryo-revival, shock nets, knockout gas, and virtual reality combat. What type of sissyness is this? This doesn't provide any reason for the other side to stop being your enemy. And how the hell do you establish discipline in a war where the greatest danger is ripping and dirtying your uniform when the
Kill Something Bitches! Really, it's one of the few things that humans are actually good at finding new ways to do. Death and sex. These are the two things that most people wonder about first when contemplating a new technologies possible applications.
