My first thought was, if someone found your book in a 100 years from now they would be displaying it in a national gallery.
If its only digital it will be lost in the ether.
Digital has its purposes of course but i worry for the future sometimes considering how much knowledge and art we've forgotten already.
We don't know what will exist when Skynet takes over! Can't see the robots quiet understanding art like we do which might not bode well.
