To me, the most unrealistic part of that ad is not the edge to edge displays, or the holograms emanating from them, or the overall inefficiency of it all, but rather just that you could never have a place that full of screens without ads being everywhere.
I remember first watching that video on my first smartphone and thinking “When will they ever make a phone without bezels?” And now they pretty much have, but my experience was not some artistic interface full of aesthetically pleasing data and art. It was a YouTube video completely surrounded by ad content.
