What will life in the future be like? What will we be able to do in 10, 20 or 30 years?
Genetic engineering (基因工程) may help us make the perfect human. Also, we may be able to bring the dead back to life. Maybe people will be able to meet and talk with their dead family members.
Over the next 20 to 50 years, it will become harder to tell the difference between humans and machines.
Perhaps we will be able to make copies (复制品) of ourselves, so we will appear to be alive long after we are dead. People may be able to find ways of putting the life of a person into a new body.
Nanobots (纳米机器人) will be important. We will use them when we are sick. For example, when we have a stomachache (胃痛), we will swallow (吞下) a nanobot and it will travel through our stomach, taking a video of what’s happening there. It will help the doctor heal (治愈) us.
In the future, computers may have feelings. They may be able to think better than us. We may be more and more interested in computers and the Internet, spending all our time in front of computers.
