In olden times, each individual artisan
was responsible for the entire product of his or her work. People's work made sense, because it included every step from designing an object to manufacturing it, and often the same person who made an object was the one who used it.
The automation of production in factories has allowed part of the artisan's dexterity and experience to be transferred to machines. But this change has also made each individual's work more monotonous. Unskilled workers who simply operate machines may feel that they are nothing more than replaceable parts, just like the things they are manufacturing.
