Most efficient media formats to come are going to have a piss poor quality

Despite increasing computing power, high quality media still presents a storage problem. If the raw file is compressed to piss poor quality with an algorithm, the same algorithm could be used to faithfully (or with a margin of error outside our sensorial capabilities) live upscale the media file back while you are playing it. So you could have a full 8k video library resting on 720p files, lossless audio coming from 192kbps files, and stuff like that, a quality good enough to embed for piss poor connections and processing power, but that can be locally live upscaled by the algorithm on better devices.

ps: Upscaling media is already real, it's just bad at the moment. Funny to see people believing it won't get better. How easily are you still telling AI videos apart from the real thing without the aid of professional tools? Just a year ago it wasn't so difficult.
