Modern technology has not always improved the quality of people's lives.

The introduction of technology a few decades ago has indeed brought about a significant change in the lives of people, however its advantages have not always been experienced by everybody.
In many countries all over the world, people have yet to taste even the most basic technology such as lighting. Although modern technology has developed in some parts of the world, there are still millions of people whose lives have not changed simply because the country does not have the capital to introduce technology to their villages. In certain parts of China and Africa, villagers are not even guaranteed proper lighting and a constant supply of water as the countries are too big and governing it is extremely challenging. During the night, many of these villagers wander around in total darkness as there are no electrical cables linked to the villages. This has made life extremely inconvenient for the people who live there, as their basic necessities are not even provided for them.
Medicine was discovered in order to cure diseases and sicknesses in the past, and it can be used in many different ways to treat people. Technology has allowed the development of medicine and countries pump in millions of dollars each year for the research of new antidotes to cure diseases. However, since its introduction many people have neglected its benefits and chose to misuse medicine. Cocaine was previously used as an anesthetic while people underwent operations as it helped to numb the pain experienced. Nowadays, drug addicts pay large sum of money to buy cocaine to experience the feeling of getting "high". There have even been articles of teenagers taking an overdose of panadol, which is primarily used to cure headaches, as a form of drug addiction. All these different types of medicine when consumed inappropriately, only damage our bodies and lower the quality of our lives.
Nonetheless, people have also benefitted from modern technology. Without it, the world today would seem devoid of living and very dull indeed. Since Thomas Edison invented the light bulb a few decades back, its advantages have helped mankind in many ways. For example, without it we would find it inconvenient to do anything when night falls as light is essential to all of us. Communication was also introduced with the invention of the first telephone by Grahan Bell and this made long distance calls possible. Previously, any form of communication required the writing of letters from one person to the other and the letters were then sent by ship, which would take weeks or even months for the other party to receive the information.
Travelling has also been made much easier with the invention of cars and planes, and it no longer takes days to get from one end of the world to the other. A flight would get you halfway across the world in a matter of hours, and this makes travelling much more convenient and safe. Although medicine when used in an inappropriate manner can be fatal, its advantages has improved the quality of life. Without it, people would fall sick without being capable of recovering and many sicknesses such as flu which were seen as fatal in the past, can now be cured ina matter of days. The research of medicine has no doubt brought up the standard of our lives, as we are now able to conquer and overcome most of the diseases by simply popping a pill into a mouth. More complex diseases or illnesses might require surgery, but still the introduction of medicine has helped us fight the bacteria in our body.
Even though modern technology might not have improved the quality of everybody's lives due to certain restraints, it's introduction has no doubt been a blessing to all mankind.
