who taught people that the world should write

There is no one specific person who taught people that the world should write. Writing has been developed and passed down from generation to generation throughout human history. The invention of writing systems is attributed to different ancient civilizations such as the Sumerians in Mesopotamia, the Egyptians, and the Chinese. Over time, writing became an essential tool for communication and record keeping, and its significance spread across cultures globally. The development and spread of writing is a collective human achievement rather than being attributed to one individual.

The person who taught people that the world should write is generally considered to be Johannes Gutenberg. He is credited with inventing the mechanical movable type printing press in the 15th century, which revolutionized the production of books and made written materials more accessible to the masses. Gutenberg's invention allowed for faster and cheaper production of books, leading to an increase in literacy and the spread of knowledge.
