Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily experience.
Automation has had a notable impact in a wide range of industries beyond manufacturing (where it began). Once-ubiquitous telephone operators have been replaced largely by automated telephone switchboards and answering machines. Medical processes such as primary screening in electrocardiography or radiography and laboratory analysis of human genes, sera, cells, and tissues are carried out at much greater speed and accuracy by automated systems. Automated teller machines have reduced the need for bank visits to obtain cash and carry out transactions. In general, automation has been responsible for the shift in the world economy from industrial jobs to service jobs in the 20th and 21st centuries.[1]

Movable type is the system of printing and typography that uses movable components to reproduce the elements of a document (usually individual letters or punctuation).
The world's first known movable-type system for printing was created in China around 1040 A.D. by Bi Sheng (990–1051) during the Song Dynasty;[1] following that, the first metal movable-type system for printing was made in Korea during the Goryeo Dynasty (around 1230). This led to the printing of the Jikji in 1377—today the oldest extant movable metal print book. The diffusion of both movable-type systems was, however, limited:[2] They were expensive, and required an enormous amount of labour
