War, poverty, global warming, starvation, racial inequalitythese, among many others, were all trivial, long overcome matters of the past.
Generation ZZZZers glided around in auto-piloted, eco-friendly, space/time ships. They communicated with each other via holographic telekinetic mind messages. (Though there was always the occasional hippie, of course, who'd pull out a vintage, non-functioning wePhone 2000 or whatever technological dinosaur was making a comeback these days. Lame, if you ask me.)
