As a follow up to an earlier post about old predictions for 2011, here's what Edison thought back in 1911 would happen "a hundred years hence":
"Books of the coming century will all be printed leaves of nickel, so light to hold that the reader can enjoy a small library in a single volume. A book two inches thick will contain forty thousand pages, the equivalent of a hundred volumes; six inches in aggregate thickness, it would suffice for all the contents of the Encyclopedia Britannica. And each volume would weigh less than a pound."
Sounds like Kindle.
