I am that weirdo data hoarder/curator. I have been saving content, text, images, art, audio, videos, games, tutorials, info and all kinds of stuff for a few years, just before the real degradation of web began around 2016. I just save videos instead of streaming them. And the fun part is you do not need that much storage space, just buy a good 4 TB HDD with an enclosure. Extra if you want backup copy.

I use general, text, audio, video, photo et al compression of all kinds, since I am an expert on that too, allowing me to make best use of storage space.

There was one friend of mine, who has their own intranet of over 100 TB. Fun stuff.
