Digital won't replace print just as the radio and TV didn't replace print (and interactive didn't replace passive, and print didn't replace the spoken word). They are wholly different ways to interact with information, each better suited for different tasks.<p>I'm 28 years old, and I buy all my books in print form. There is something about learning from a physical object (with volume, texture, scent) that makes things "click" better. I remember "where", within some textbook I read half a decade ago, some topic is explained. A literal, physical "where": a page, somewhere in the middle of a physical stack of bound paper, which I can touch and feel; I might event remember where I was when I studied the subject; maybe I jotted some note on the margin, maybe I spilled tea on the pages before, giving that "where" its own unique texture and colour, all of which my brain will forever associate with that information. Digital can't do any of that.<p>There is nothing left to improve about the physical book.<p>Of course, if my physical book confuses me, because perhaps it was written by a certain man named Spivak, who does not like to explain what happens in between those little "=" symbols, I can't press on anything and expect it to expand magically and reveal more detail. It's at this point that I will turn to my laptop, and search for more information, maybe even ask a stranger half a world away, or watch an interactive video. My copy of "Calculus on Manifolds" can't do any of that.<p>I also still find that the best way to solve a problem (even a programming problem), is on pen and paper. Physically jotting down an idea beats pressing buttons while staring at an obnoxious, headache-inducing glowing screen any time (which I try to avoid as much as possible, even as a software developer). To me flipping still beats searching and clicking, and pen and paper still beat Google calendar, or whatever todo-app-of-the-week.<p>The best technology is invisible and gets out of the way. We are physical animals, and technology is best when it assists and enhances our physical world, not when it tries to be a shoddy substitute for it.
