You presume the things I want to save aren't individually TiBs in size.
Anyone who has even an amateur interest in, say, making movies, probably has at least a few projects worth of 4K RAW footage they would hope outlives them. (And the average small-time YouTube content creator has far more.)
I don't know, i don't think any one after me is gonna scrounge through hours of raw footage of an old project of some grandparent (me). Not that I have kids but anyway.
If anything I doubt they'll bother looking at the final cut.
