Maybe not as world shaking as milbots or healthbots, but if you're Google or Amazon, or possessed of a very large dead tree library, you'll want Kirtas Technologies' Bookscan (check out the video). If you've ever had to get legacy printed material into a scanning or OCR system, hands-on or just paying the bills, you'll appreciate it. Gadgets like this as well as the search engines' book indexing projects will slowly break down the "Internet Event Horizon" that's made a lot of information created before the mid-1990s invisible to the net.
