This world is full of the benefits of technology. As technology changes, our life will be influenced in almost every aspect.First of all, our environment will be more pleasant, because electricity will be produced from clean energy instead of coal. Secondly, our cars, which can travel not only on the road but in the water, will be controlled by a robot; in this way, traffic accidents will be avoided. Additionally, some new medicine will be developed so that people can live longer. Thus living to 120 years old may be no longer a dream.In conclusion, I think life in the future will be much better than it is now.
