No, 8K is not really reality at the moment, but editing UltraHD is reality, and being able to easily edit or composite 2/3 streams of UltraHD with some complex effects in realtime is desirable. It's a bit mind-bending for those of us who remember the SGI Octane and Onyx days to think that 100x as much computation is available at 100x less power-consumption. (That's 10,000 times more efficient, for those following along at home.) Between that and the almost infinite instantaneous computation power available in the cloud at the press of a few buttons (and sufficient capacity on one's credit card), we ain't in Kansas any more.
