it’s incredible how futuristic sci-fi stuff is self fulfilling??? like. back to the future created (or at the very least increased) a demand for hoverboards, flying cars, and now we actually have shoes that can self lace. it’s just amazing to me.
and then you’ve got stuff like star trek, with PADDs that became tablet computers, and communicators that influenced modern mobile phones. REPLICATORS BECAME 3D PRINTING. so much media dreamt of video phone calls and landing on other planets and wireless broadcasts. edward bellamy predicted the damn credit card in the 1800s, for god’s sake
in conclusion: WRITE ABOUT COOL THINGS THAT DON’T EXIST. real people in the future will also think they’re cool. and then they’ll make them for you
