That's what business consultant Ross Dawson thinks, as mentioned in Slate's very cool library architecture slide show. (See his Extinction Timeline.) The above photo is one of the images from the slide show, depicting the Western History Reading Room at the Denver Public Library.
Libraries are certainly more than a place that stores books these days, providing computer and Internet access and training, a public meeting space, programs, and other wonderful things. Are they truly doomed? I hate to think so - and not just because I work in a library. Libraries have always been one of my favorite places to be, from the time I was a child. They have offered me way more than books over the years - I sure hope they aren't really headed for extinction.
