Relationship To Mechanisation and Automation
Mechanisation and automation strive to reduce the amount of manual labour required for production. The motives for this reduction of effort may be to remove drudgery from people's lives; to lower the unit cost of production; or, as mechanisation evolves into automation, to bring greater flexibility (easier redesign, lower lead time) to production. Mechanisation occurred first in tasks that required either little dexterity or at least a narrow repertoire of dextrous movements, such as providing motive force or tractive force (locomotives; traction engines; marine steam engines; early cars, trucks, and tractors); digging, loading, and unloading bulk materials (steam shovels, early loaders); or weaving uncomplicated cloth (early looms). For example, Henry Ford described his efforts to mechanise agricultural tasks such as tillage as relieving drudgery by transferring physical burdens from human and animal bodies to iron and steel machinery. Automation helps to bring mechanisation to more complicated tasks that require finer dexterity, decision making based on visual input, and a wider variety of intelligent movements. Thus even tasks that once could not be successfully mechanised, such as shelf stocking or many kinds of fruit and vegetable picking, tend to undergo process redesign (either formal or informal) leading to ever smaller amounts of manual labour.

“... the Wall became a magnet for citizens of every generation, class, race, and relationship to the war perhaps because it is the only great public monument that allows the anesthetized holes in the heart to fill with a truly national grief.”
—Adrienne Rich (b. 1929)
“It was a real treat when he’d read me Daisy Miller out loud. But we’d reached the point in our relationship when, in a straight choice between him and Henry James, I’d have taken Henry James any day even if Henry James were dead and not much of a one for the girls when living, either.”
—Angela Carter (1940–1992)
“Besides black art, there is only automation and mechanization.”
—Federico García Lorca (1898–1936)
