Modern Time:pros and cons of new technology

First,Chaplin was a factory worker in the film. His job was tightening bolts in the film. Therefore, he should repeated the same work again and again  in the production line with industrial machinery, which made him jerky and never stop the rhythmic movements of his nut-tightening even during a break.
Second, Chaplin and other workers were observed every time in the factory by the boss with the closed circuit cameras,which made Chaplin nervous despite he wanted to takAlsoe a rest,the boss ordered him back to work.Also,beacuse of the order of the boss through the closed circuit cameras,the speed of the production line increased gradually.That caused Chaplin's problem(the jerky and rhythmic movements)more serious afterward. Finally,he has gone crazy completelly.

What I experience with digital technoligies which is similar with the film,is typing on the computer.When I type a lot of words and repeat the movement of the fingers with the keyboard on the computer, the fingers
will be tired. Likewise,using the computer to work or access to the Internet to browse the web pages, the trigger finger and the shoulder will be hurt because of maintaining the same posture or gesture for a long time.
