> So it seems like filmmakers predictions either grossly mispredict the amount of technological progress at the big scale
It is said sci-fi is less about predicting the future than to preventing it. I'd go more with the idea it's about showing what can be and helping us finding our way there (or out of there).
While some people predicted the Internet, or something like it, no one predicted Internet culture.
And I don't think anyone seriously imagined that the Internet would be accessible through a terminal you could carry in your pocket that also worked as a clock, camera, calendar, video and audio phone, calculator, weather forecaster, fitness monitor, games machine, and smart personal assistant.
It's debatable if a moon base would have been better. I suppose a moon base would have created cultural changes of its own, but I'm not convinced they would have been as disruptive as the Internet. (And it's just getting started...)
Gibson came close to both hacker culture and the first world anarchists ("Panther Moderns" ~= "Anonymous"). And Asimov's "Multivac" has often been compared to the internet.
I think some of the predictions were probably driven by the expectation of large scale government funded projects, rather than incremental consumer driven advancement.
