Su's writing assigment

Since a long time ago, human invented machines to help their lives easier so that they could concentrate on researching something more prodigious. Now we have to ask ourselves: "What are we, masters or slaves?". The answer is:  we have become too dependent on them that now we cannot do things our ancestor could do without them. This is a very negative development because instead of being better, we are now becoming less" intelligent" and leading a sedentary life.

To be honest, we cannot deny the benefits that machines have done to us. However, machines should always be serve only as a tool, not what we cannot live without. Take solving math problems as an example. Before the invention of calculators, our predecessors was adept in solving math problems without the help of anything. Therefore, it is both sarcastic and sad to see that students today consider the calculator as a must-have life saver. Since the later generation of the calculator inventors had to rely on it to do simple calculations with the excuse of "double-checking", and since the invention meant to  human's wisdom, turned out to be downgrading it.

Moreover, by depending too much on machines and advanced technologies, we have eventually led a sedentary life. In the movie "Wall-e", we can see the future humankind if we continue to rely too much on machines. Big, fat, slow people were sitting on a digital chairs that provides people with everything they need without moving a finger. We could be laughing very hard when watching a man and a woman speak to each other face to face like they have never spoken before or when the spaceship captain made an enormous effort to lurch heavily after a long time sitting on digital chairs. However, those moments will become reality if we depend too much on machines and let them do all the work.

In conclusion, it is true that technology made our lives comfortable, but an overdose of anything will just do harm. We are the ones who created the machines, so we are the ones who must take control of them.
