Gutenberg's printing press democratized knowledge and fueled the Reformation, Scientific Revolution, and Enlightenment. Without him, none of the others' ideas spread the way they did.
Jesus sparked Christianity, which shaped laws, culture, and ideas for over a millennium before Gutenberg. The press just spread what Jesus already set in motion.

Yes, Gutenberg mattered; his press widened the reading public and the market for books, fueling literacy, trade, and the spread of knowledge.
