I think whatever special value books used to represent in our society from before the internet is long gone. I remember the pre-internet times when the information world you had access to was small. You could consume silly low-information things on the tv or radio or you could read a book on the topic, which had a much higher information density and chance of being correct. There was no one you could talk with about a detailed topic unless you had maybe built up a professional circle you met with regularly, so a book was your only opportunity to "converse" with an expert. If you paid thousands of dollars, you could take a class on the topic and have an knowledgeable person take you on a basic guided tour of some of the good books on the topic. You would never have been able to get Warren Buffet's detailed thoughts on the economy without reading his book.
In the post-internet world, information is cheap and plentiful. Endless hours of talks and interviews by major thinkers are available to all. With a quick Google, you can find people discussing any topic under the sun. Micro-niche content on all topics are being produced for YouTube, the likes of which you would have never seen on the Discovery Channel. Dozens of free courses are available on all major topics and you can cherry pick just the pieces you are most interested in. Most information can be just-in-time delivered to you at just the moment you need it. Books are not obsolete in this environment, but just another one of the dozens of formats through which you could consume detailed information on a topic.
And finally, our collective societal values change slowly in comparison to the pace of technological change. Books were far and away the best way to access information for so long that it has a sticky association with class, intelligence, wealth and wit. But really, if you are getting all your information from books, you are an anachronism and definitively behind the curve. Sometimes I think of Raphael's School of Athens and think that the conversions I've been privy to for the past 10 years on HN must far surpass anything they might have said to each other.
