>It is baffling that Bradbury was able to write The Murderer in 1953.
I thought I had a decent grasp of science fiction classics of that era. After reading the story, I too am baffled, both by my having missed this story, and in the same way you are.
>I am not aware of a more prescient bit of science fiction. Bradbury knew how people worked and what we'd try to make.
While not a start-to-finish prophecy like "The Murderer", from Wikipedia's article on Robert Heinlein's Space Cadet:
>The novel contains an early description of a mobile phone:
>>Matt dug a candy bar out of his pouch, split it and gave half to Jarman, who accepted it gratefully. "You're a pal, Matt, I've been living on my own fat ever since breakfast -- and that's risky. Say, your telephone is sounding. "Oh!" Matt fumbled in his pouch and got out his phone. "Hello?"
>The phone "was limited by its short range to the neighborhood of an earth-side [i.e. terrestrial] relay office".
I especially find this part insightful:
>A cadet avoids having to talk to his family while traveling by packing his phone in luggage.
