and its kinda funny to watch old science fic movies that were made in the past.
Total Recall... in that futuristic world, there is no wifi, Arnold needs to find a device to extract and play a video file.
that would be either a time travel drive(eg dr who) or the infinite improbability drive(hitchhikers guide to the galaxy) the time travel drive can go to any point in the time space matrix( so can arrive BEFORE it leaves), and the infinite improbabililty drive can also travel in the time axis(s) also arriving before departure.
