Bonus: If I buy a book I get to keep it! The publisher can't turn up at my house at random and confiscate all the books I bought.
Also, the pure hubris of saying we never recognized how shit ads were even back when they started being put into newsprint.
Depending on the definition, we have a lot of data about how durable "cloud storage" is.
"Cloud storage" is a marketing term for transferring files to a company that manages a huge number of computers with a huge number of hard disk drives (HDD) or solid state drives (SSD). The expected average lifetime of a HDD is somewhere around 5 years. The expected average lifetime of a SSD is somewhere around 10 years.
The only reason to get around this short lifetime, is by copying the data to new drives before the old drive crashes. This is made very easy by techniques that hold the data on multiple drives, and when one drive crashes, it is replaced, and the system then replicates the data that was on the dead drive onto the new drive. As long as the system is running and drives are replaced as they fail, the system works.
The moment you stop replacing drives, you have barely more than a decade of reliable data retrieval.
Digital systems have one advantage over physical books: It's very very very cheap to copy the information stored.
Have you considered how much music recorded in the 00's are lost because MySpace didn't consider themselves an archive? Most music uploaded to that site is gone. And there's a significant amount of it where even the musicians themselves don't have a copy, because it was only ever digital.
