"Nobody" is obviously the market that RED is targeting with their 8K cameras (shooting raw/lossless for that matter) or various projector manufactures. Sure not everyone in the production pipeline is going to be watching manipulating the edit list in 8k, but you better be sure there are a few people looking at the dailies at full 8k res before the OCD/dictatorial director shows up.
Apple obviously thinks there is a market here too, or they wouldn't be talking about how the machine can show three simultaneous 8k streams.
