Got a good question here...
If the fiction in the science ends up being factual in the future (real world), is it really science fiction then?
For instance... Star Trek: Communicators; Real World: Cell Phones, Star Wars: Turbo Lasers; Real World: real laser weaponry, Star Trek: transparent aluminum; Real World: real transparent aluminum, Star Trek and Star Wars: energy shields; Real World: a device currently under research and development that emits a powerfull micro wavic field that protects anything inside of it, Star Trek: transporters; Real World: another device currently under research and development that does the same thing, Star Trek: Cloaking device; Real World: a cloaking device of sorts (not exactly like in Star Trek though). Other science fictional ideas that had been made that are now under research (and development?) are warp drive, artificial gravity, holo suites (the full surround holograph part is already developed), hypo sprays (already developed), tricorders (already developed), and a bunch of other stuff that once was fiction is now factual.
