Thank you for your reply and request for clarification.

Yes destroying a book is in my opinion identical to a book burning.

One day there will be no hard copies, the digital books are hence vulnerable to patches, whether its due to a new political movement or a sudo abled hamster running on a keyboard... and if that occurs information will be permanently lost.

I would have thought a HN user understand well the importance of backups.

I dont want to sound mean, perhaps you also support keeping some hard copies as backups, but Im just explaining my concern.

To be honest I think everything I am saying is just common sense, I was just making a joke earlier about the architects deciding to do this because they had a bad tuesday.
