Cool tech video, but in reality it's just a concept. Getting all those screens in place and working is not too hard at all - the difficultly is in creating a seamless UI that flows and smoothly and as integrated as what's shown in the video. That's not so easy. The challenge is in the software.
Overall I think it would be cool, but I don't see us getting to that point of integration. "Futurists" are notoriously off-base on predicing the future. Look back at 1960's science fiction and they're talking about flying cars (probably never gonna happen) but pulling computer information from "data tapes" (which sounds down-right archaic these days
). The uber-clean futuristic scene has to make way for the reality of messy desks covered with papers and empty Mt Dew cans
.
Still, I think we will see some level of this in a more "contained" fashion. Rather than everything in your world having a screen, you'll likely still have your computer monitor when many things happen centrally. Just easier to pull out and fix that way. I'd wager that soon it would also be common to have a tablet that can be used to control the television if desired, and the idea of the screen in the center of the car is likely, but the tables, windows, and bus stops? Nah, I just don't see it.
