As technology normally makes things go faster, which it then creates problems as with many things technology is out pacing the time that it takes for a lot people to adapt. Recent press releases about ebook sales show that they increased over 200% in the last year, making ebook sales higher than print sales for the first time (with print down 34%). This kind of change isn't new, but for may they just were not expecting it to happen this fast for print. Music publishers were surprised at the MP3 revolution, TV was surprised at the video recorder/tape revolution, I wouldn't be surprised to find out that stove/oven makers were surprised by the microwave. Although, here fast is a relative term. The first mention of devices like ebooks that I can find occurred with Robert A. Heinlein's Space Cadet from the 1950's, and I've been attending the conference on electronic books for over ten years, but when it actually happens it catches many by surprise. I'm always reminded of the book Everything is Miscellaneous when I hear these things, as a similar issue occurred when people changed from scribing to movable print. I don't think that things will ever switch over to digital only, at least in my lifetime, but I do feel that it will change for the majority.
