Throughout history, inventions have made life easier by improving agriculture, manufacturing, and technology. In the pre-industrial era, Johannes Gutenberg's printing press allowed for the spread of information. The industrial revolution saw inventions like John Deere's steel plow and Thomas Newcomen's steam engine that increased farming and manufacturing. The modern era brought even more innovations, such as the Wright brothers' airplane, the silicon chip enabling computers, and Henry Ford's assembly line for mass production.
