No matter the quality of the paper, it will eventually decay. If you can still read your book from 1640 that's really great but realistically how common is that? There are a lot of environmental factors that affect paper duration and in many areas of the world, a decade is already very long for paper (have worked with an NGO based in Thailand that has 15 years of archives; the first 5 years are hardly readable)
As I said, digital data has the potential to exist forever. Digital data is independent from the media. A media is mostly cheap and disposable.
> Now, if you think that every book with stereotypes should be discarded, that's sad.
I certainly didn't mean that (cf. "gold mine").
> We have the responsibility to preserve history, and the moral duty to challenge what we consider wrong with our reason.
My point exactly. Which is why my comment invited the op to get a data dump and archive it properly. We all know that paper is sensible and would be careful for storage. We need to build and apply a similar set of precautions to store our digital data.
> To wipe it off, that's censorship and a recurrent disease of totalitarian mindsets.
Definitely OT.
