In the last century many people did things by hand but nowadays more and more tasks have become automated. For example, many people have washing machines, clothes driers and dishwashers, so the amount of energy needed to wash and dry clothes and wash dishes is greatly reduced. As technology progresses, more and more of these tasks will be automatic, for example, vacuum cleaning or cutting the grass. In addition to this, improvements in technology have given us 24-hour a day entertainment from digital TV to video games. This means that there are fewer tasks to do, more time to do nothing and more opportunities to sit around and be entertained without moving very much.
As we can see, there are both advantages and disadvantages to this. I will deal with the advantages firstly. I think, there are at least two positive effects of this. First of all, we don't need to do repetitive and uninteresting job like washing-up and this gives us more time to do other things. What we do with this time depends upon the individual. Secondly, for people, who are less able to do these jobs, like elderly or disabled people, these machines are a great help. Future developments may be able to help them even more. I think, this is the most positive side of technology.
Now I will look at the disadvantages. As I mentioned, it is up to the individual what they do with this extra time. Unfortunately, instead of doing everyday tasks people tend to watch television or play video games. Furthermore, television companies encourage us to watch as much TV as possible. this can lead to an inactive lifestyle and people are becoming overweight and unhealthy.
In conclusion, the positive side is that because machines and automation do the things we do not like doing we gain more time to do other things, and people who cannot do certain things are able to do them with the help of technology. However, on the negative side we lose the daily activity involved in washing-up, vacuum cleaning and so on, and for some people, this may be the only kind of activity they do. The danger is that we do not replace these activities with others.
