There is virtually nothing with advantages that doesn’t have its disadvantages. As good as the uses of machines are, they also have their shortcomings. Machinery are first created with no harm and are made to make life easy, increase production and also for accuracy but humans now use machinery in a void a manner causing laziness and harm to them and people around them. Machines on its own also affect the economy state through high rate of unemployment. The major disadvantages of machines are discussed further.
Machines are expensive to buy, maintain and repair. A machine with or without continuous use will get damaged and worn-out. Only the rich have access to good quality machines and also its maintenance. Machines are very expensive when they are compared with human labour that is cheap and available. When there is no or unstable electricity, some machines need an alternative means of power (the use of generators and power plant) which will increase cost in terms of fuel and maintenance.
Machines generally are difficult to understand, set up and operate. Many machines are made in foreign countries and are being imported. Some of the manuals of these imported machines are written in foreign language(s) with no or little interpretation. When such machines are being purchased, the users may encounter little difficulties in its operation. This problem is always solved with the help of operators but sometimes the operators also find it hard to interpret the usage if the machines are of new brands, uncommon or limited in supply.
The repeated use of machines leads to monotony and boredom. Knowledge is being restricted and advancement, excursion and the addition of knowledge is most likely not possible. Boredom, depression can also set in when there is no change or when one is glued with the use of machines. People are more lazy, less dedicated and will not be encouraged to task their brains, make use of their potentials or go extra miles with the use of machines. All they need is to press buttons, cursors and they have their work done.
In capital intensive industries where there are more machines than labour, there will no or little interaction with colleagues and co-workers. Workers are expected to interact with their machines for hours with no chance of seeing outside the walls of the workplace or having visitors. Workers are being alienated from other people when machines are used. By this, their social lifestyles are being damaged unconsciously.
When a man or woman is used to machines doing all the work, he or she is prone to health challenges like depression, obesity and hypertension. Also, the use of machines in industries can cause injuries, accidents, loss of body parts and even death.
Machines release waste products and poisonous gases which are harmful to the environment, man’s and animal’s health. This is one of the great risks machines pose to life. Apart from the poisonous gases, noise that generate from heavy machines can lead to deafness and harm to the auditory nerves, the release of waste products can contaminate the water bodies, thus, resulting to water-borne diseases, death of aquatic organisms and the displacement of the biosphere.
The economy is now more of capital intensive than labour intensive as less people are now employed. This is so because machines have replaced man labour. In recent industries, machines are more than men.
With the use of machines, hand work creativeness that were rampant in the traditional era are reduced. The use of craft, beads making, hats making, raffia works are gradually going into extinction.
