I think that the question comes down to technological advances. It is impossible to fully evade the grasp of technology. The fact that this conversation is taking place with people from all over the world via the web indicates that technology is here. On one hand, this might be one of its positive attributes. Consider that enotes, as a form of technology, allows students to gain insight on topics that they are studying and distance or time does not seem to matter that much. At the same time, I think that being able to limit the role of technology through self monitoring might be important. Any venue that makes life easier can have a tendency to become addictive and something that can make life more monolithic as opposed to multidimensional. Technology does make life better, but it might also create problems of dependence and a sense of inward trajectory that could cause a lack of focus in the interactions with the external world. There is a balancing act that is needed.
Your statement isn't asking a question. It seems as if you might be either looking for support, or as if there is a great 'but' hanging in the balance. So I will look at the opposite for you.
This depends on your definition of the quality of life, right? I have problems with my relationships with people all the time and no technology ever seems to help me deal with them. In fact, it rather hinders them. For example, I would like my children to learn to be respectful and honest, but even the television shows that we allow them to watch demonstrate sneaky behaviors or rude comments that they try to repeat or mimic. Furthermore, I would like my children to learn to be healthy by exercising and eating a good diet. Video games, cell phones, and the internet all help keep them sedentary while commercials the see entice them too eat poorly.
At work, I have a co-worker who lost a portion of her position to me. My boss requested I write her an email to retrieve a document that only she had. The email was kind, but the fact that I didn't come to her in person for the document hurt her feelings to the degree that she won't talk to me anymore.
Unfortunately these are human problems derived by humans, but you can see that technology played a role in creating them. A great opposition to technology would be that it is dehumanizing. It removes a human element that we need to remember to maintain in relationships.
On the pro side of this question, you can mention things like computers and cell phones and medical technology. Computers and cell phones have solved the problem of how to communicate with others and exchange large amounts of information very quickly from wherever we happen to be. Medical technology has allowed us to live longer and healthier lives. There are, of course, many other examples.
To argue against this, you can use the same fields. Computers and cell phones have made people busier. They have made it so workers are never able to get away from their bosses or the demands of work. They have allowed for bad things like internet pornography and identity theft. Medical technology has cost vast amounts of money to do things that do not need to be done. We keep people alive even in circumstances where death might be "better" for them. In addition, it keeps the population of the earth too high.
