Books aren’t obsolete yet, but they’re clearly going to be.
Consider all the paper media that already is obsolete: reference books went obsolete first, simply because new editions take so long to prepare, and they are too bulky to be portable anyway. Web-based references are more accurate, and, now that telephones have internet connectivity, more portable as well.
Newspapers and magazines are rapidly becoming obsolete. Subscriptions are dropping and readership is aging. Again, as internet connectivity becomes easier and more portable, the benefits of carrying paper around with you to read news that’s a day or a month old keep dropping.
People in this thread are talking about mainly mass-market books, the kind that you can stuff in a backpack (or a back pocket) and read when you feel like it. The major factor holding back electronic readers on those fronts is cost and the ability to share. Cost will come down. In 10 years, the equivalent of the Kindle, which will be far more comfortable and feature-rich, will cost $50. It wouldn’t surprise me if they start giving them away with some purchases. Sharing will work itself out, too. Either companies will offer titles that can be transferred, or piracy will fill the void, or the publishers will hold out long enough that social attitudes about books change, and people will accept that you just can’t resell written works. I’m hoping for the former, but any of the above will allow electronic books to supplant paper ones.
The claims that books will never be obsolete because the feel of a book is special, or because you can’t fill a bookshelf with a Kindle are, frankly, pretty silly. Do you drive a car with a manual transmission? Do you watch movies only on a film projector? Do you listen to music only on vinyl, and write letters with quill pens and manual typewriters?
Yeah, I’m sure that a few of you do do those things, but the vast majority of people don’t. Convenience will win out over aesthetics in the mass market. There will always be a niche of book collectors and archivists that will guarantee that some limited print runs are made, but as far as the current distribution model, with bookshops in every major shopping center, the writing’s on the wall.
