I think it's naive to asume we know how displays will be used in the future. Consider parallax barrier displays[0], an option for the navigation system in Range Rovers since 2010 so that the driver can see the moving map whilst the passenger can watch a movie. Two images on one display, also mentioned in the author's brief discussion of 3D television, would certainly benefit from higher resolution. Perhaps displays of the future will allow for parallax perspective as you move around the display. Perhaps that'll be the first application of 8k television[1].
