Ray Bradbury’s Predictions
Not to denigrate Bradbury, but… is this supposed to be serious? Wrist radios and robot bank tellers foretold cell phones and ATMs? Those are some pretty broad readings, you must admit.
Besides, most of these ideas predated Bradbury’s stories by a pretty wide margin. In at least one case, the implementation predates him: the first mobile phone call was made in 1946, seven years before Bradbury is supposed to have thought up the idea. (And the idea was over a decade before that, when they started researching it.)
Seriously, Bradbury was one of the most brilliant writers of the last hundred years or so. But let’s remember him for what he actually did do, which wasn’t predicting future technologies. No SF writer has ever done that successfully. At best, they’ve given us logical extrapolations of existing technologies, and perhaps inspired future designers and engineers to replicate their visions. But for the most part they’ve given us fantastickal mechanisms wrapped in sciencey-sounding terminology, so they could tell their stories without those pesky laws of physics getting in the way.
