Yeah but at the same time, if you look at most sci fi movies from 20 years ago, they waay underestimated the actual progress that happened in things like computers.
The opposite is true. Compare an 8086 running DOS (1978) to a Pentium II running Windows 98 (1998) to a Core i7 running Windows 10 (2018). Progress has slowed down immensely. Look at other things like voice recognition, video conferencing, and VR. Dragon Naturally Speaking came out in 1997; I don't think anyone predicted that more than 20 years later, voice recognition on iOS/Android would still be so awful (and not work without an Internet connection). Likewise, I don't think that anybody would've anticipated that video conferencing would still suck, and most people would still prefer using voice phone conferences. At a more technical level, I don't think anyone anticipated that a 1970's era UNIX clone would be the dominant operating system, that we'd still be writing apps in Objective C, etc. Visual programming, micro kernels, object components systems--none of that stuff panned out either.
