If any printing technology from later periods of time were to exist when earlier printing began, it would be clear that printing and reproducing books would be significantly easier, even cheaper. In the case of lithography, type would not need to be set to print a new page. A new sheet of text needed to be made only once and could be reused for the amount of times needed. If the page ever needed to be printed again, the sheet would just need to be set again, without excess effort. This, however, would cut down on jobs. Vast amounts of time would not be used and an employee would not need to set up text every time a page needed to be printed. Overall, less employees would be needed, which would cut on costs, and less effort would be necessary, further cutting costs.
In the end, the process of making books would become more profitable for publishers, and with copyright, for the authors as well.
The one thing that makes me nervous about this is the loss of jobs involved. I feel like with our society struggling already changing anything that eliminates jobs can be very dangerous to our struggling economy.
People can find jobs writing the pieces that will be getting printed.
