The term ‘Industry 4.0’ appeared for the first time in 2011 and saw the
introduction of many cutting-edge technologies such as Cyber-Physical
Systems (CPS), Internet of Things (IoT), and Digital Twins (DT). World
leading scholar Warren G. Bennis was quoted in 2016 as follows: The factory of the future will
only have two employees: a man and a dog. The man will be there to
feed the dog. The dog will be there to keep the man from touching the equipment.
