I feel the same way. The last time I read Kevin Kelly's Out of Control, I had a similar experience — constantly searching for materials, adding supporting arguments, and feeling as if I had retained nothing after just one read.

After reading the description, I'd say this is one of those books that interprets phenomena around us in a novel way, without claiming we should jump off "the shoulders of giants." There have been several like it in my reading history, but since I can't name them instantly, they probably weren't that thought-provoking.
