Inventions cause society to adopt new ways of doing things, while ending some occupations and creating new ones. Whether agricultural, mechanical, chemical, or electrical, inventions that make things easier or faster will result in greater productivity or commerce. The world economy is based on production and trade, and anything that influences how they occur will inevitably alter human society.
