I don't really feel books will disappear. I know personally I read most of my books on ebook, but on occasions I will go buy a book of an author I like and I know many people do the same as I do. Also the library of congress made it its goal to archive all the knowledge both to a giant database as well as in the paper form. So I feel the article is slightly off in that regard.
Won't disappear completely, just as mechanical watches haven't ... but they'll become luxury items, focused more on "I want this and I want it as well-made as possible" than the functional content.
I've got 26 bookcases at home. The prospect of moving is staggering (last time the sheer mass bumped the predicted cost by $2000). There are piles of books I so want to read but know I'll never get to ... and will never part with. Oh, to have electronic copies of 2/3rds so I'd at least have the content for the prospect of reading some day without the weight/volume, and to replace the remaining 1/3rd with high quality renderings for the sensory experience of "I _own_ this".
