I'm really just being contrarian here, but anyway your claim that "You want a publication format that warps itself to the current knowledge and mindset of the reader" neglects the the ways in which the current knowledge and mindset of the reader are shaped by the medium itself. An infinitely adaptive medium results in a flabby mind that never is exercised to adapt itself to any "other". Books require attention and discipline, which reinforce focus and comprehension. Digital media are useful too (obviously), but books aren't going away for people interested in serious study.
Books force you to actively chew on the information you're consuming; digital content is generally pre-processed to make consumption effortless but often lacking in nutrition. A truly well-written book can not convey its message in less words than it uses; if someone cannot process 30 pages worth of content then their comprehension has an upper bound. I've had to fight for my attention span and would encourage anyone else who struggles with reading to start practicing with YA novels to build up the mental muscles required to get through the tough stuff.
