Most — but not al — of science fiction is optimistic. It is full of shots of a planet that is generally healthy, green and vibrant outside of whatever war zones and destruction is “the other place.” Humans are handsome, youthful and prosperous.
My favourite part is that often money does not exist, and we all float around in an existence of fitness and fulfilled potential, creativity, smarts, laughing children, none of whom are riddled with microplastics.
