This is Just a thought for increasing extropy. If there was a general purpose book scanner that was a consumer PC peripheral (<$400) imagine how many years earlier we would see the singularity. Lay your book face down on on page 1 on the scanner bed, clip the front and back cover, go to bed. Expect an explosion of World knowledge available on the web - even though mostly illegal. Maybe the big boys are not interested in a product that might find itself as an enemy to all the worlds publishing companies. The scanner part of this product could be bought OEM cheap. The mechanical part could adopt technology from document feeders of copy machines. Add a little (err: a lot) software to existing OCR routines and wall-a. Wake up to your HTMLized book. Hurry up y'all, I got my visa card ready.
