In the video below you will see a book being printed. I hope they hang on to a few of these old presses. You never know when we might need to go back to them. Even though it seems all writing is being done digitally with books able to be printed on demand, we all know that computers and electronics are almost ephemeral.
The Kindle or Nook or iPad you have today may be obsolete tomorrow. What will you read if the power supply is interrupted for more than a week? In a real disaster, books can even be burned to keep you warm.
Of course, preserving the presses isn’t enough. We need to also have a few people who remember how to use them. We’d need the materials for printing and binding. Otherwise, we might find ourselves someday in world with no books.
