This is what Mark Twain has to say about the Gutenberg Printing Press many many years later after it's invention circa 1450:-
"What the world is today, good and bad, it owes to Gutenberg. Everything can be traced to this source, but we are bound to bring him homage, ... for the bad that his colossal invention has brought about is overshadowed a thousand times by the good with which mankind has been favored." American writer Mark Twain (1835−1910)
The most fascinating aspect for me so far is the Gutenberg Printing Press, movable type and it's parallels with the internet.
