In Minority Report, set in 2054, Tom Cruise has transparent discs half the size of CDs which hold high quality video that can be projected. Spielberg consulted scientists from MIT ( and elsewhere) to visualize a futuristic home.
Now, even in 2002, we saw the beginning of the decline of personal storage tools with every digital content moving to the cloud. Although we have Bluray today for super-high-defintion content, in about 10 years when the information infrastructure is strong & deep and processing powers are manifold than what we enjoy today (when is Moore's law going to hit the physical limits and stop working?) every audio & video will be streamed from the cloud, it will be of supreme quality and there won't be any buffer time.
Did the MIT guys not see it coming? Or did Spielberg refuse because it would be a bland sci-fi prop to see a video clipping from the web compared to those cool mini-discs?
