Human being and technology. In the nineteenth and twentieth centuries, we saw the rise of industry: a lot of old jobs, that we had to do with our arms, had replaced by machinery. In a famous movie of Charlie Chaplin, ''Modern Times'', we see the relation between man and machinery. The film talked about the life of a worker inside a production line, where due repetitive gestures, he became crazy The machinery does this: transform a man in a robot. Nowadays, we can see that a great part of old manual job, in each work and field of production ( above all manufacturing) is replaced by computer and machines. This is a solution to improve the production and reduce costs and time. But the human brain is one of the most perfect machinery ever invented; would be a pity get rid of it! In fact our nature gave us the power to face the problems and accidents, and find a solution. This kind of things is impossible for a computer, that is programmed just to execute certain numbers and kind of operations and orders. At last, we are more reliable to solve the problem, but not so smart enough to not commit it. Technology should be used to avoid human errors, and to help human beings to live in a better way, but for sure, a machinery shouldn't never replaced a man in his job. Work is the real reason to deserve relax; if you don't have a job, you can't enjoy the free time.
