Not a good thing to think of books going away like 78 rpm records or 8mm home movies. I read at least a book a month, but many I buy used or at discount. I read fiction, stuff like King, things in paperbacks. On a kindle-type device? never. I read in bed, in my car while parked, on the can. The book is easy to carry around, easy to read, stop, read more. I read them and pass them on. Couldn't do that with the electronics books.
We need to keep books alive in their present format, but that doesn't preclude adding additional formats to the printed word. This change should not be stifled. Just remember, change needs acceptance, and there are cycles to that change. At some point, someone will say, 'ok, we tried that, it sux, now take it away'. Change is self-policing.
But with books, humanity needs to retain them in their present format. Anyone who has vinyl and tries to find a turntable, or has 8-trax and needs to buy a player will tell you, technology dies, and the information on media along with it, but I tell you, a book on the shelf, no matter how dusty and dog-eared, is always available for reading.
Mind you, this has little to do with the publishing industry as it is today. They are only the means to having books to read. If that industry went away in its present format, another industry would replace it, because what is essential is The Book, not who makes the money putting it in my hands.
