> I struggle to generate more than a few hundred MBs per year

There are so many (legal) use cases for TBs of space... Photography, video editing, 3D graphics, 3D simulations (think VFX explosions, destruction), ML/AI, Dataset curation/archiving, backups, doing Rust development (each target/ directory ends up being GB large usually), and so on.

Some weeks ago GPT-OSS was released, so I wanted to play around with the 120b weights, they take ~60GB of disk space already. Imagine that same thing every time new open weights are released, and you end up with +TB large collection relatively quickly.

Seems to me like the reverse. I have more and more friends asking me about how to setup self-hosting for music, tv-shows and movies, especially when Netflix et al do their monthly purge of content and some friend noticed their favorite show/music is suddenly gone because some contract with a 3rd party expired.
