Duong: Good points. Also we may be able to live on other planets, and overcrowding won’t be a problem any more…
Nick: And I like the idea of having lessons at home with a robot, and the Internet.

I disagree with the idea that robots will only benefit humans in the future. Robots will also have many negative effects. First, they will be very expensive and we will spend too much money buying and fixing them. Second, robots in factories will be able to do everything that workers do, so robots will make them unemployed. Third, the robot in our family will do all the housework for us, so we will become lazy and passive. In short, robots will do many things for us, but they cannot improve the quality of our lives.

Guide to answer
I don’t agree with the idea that with the help of technology, students will greatly benefit from studying by themselves at home. First, They still need teachers to explain the idea for them. Sometimes they understand incorrectly and teachers can help them to understand correctly. Second, teachers are more inspiring than machines, so learning at school is much happier. Thirdly, students can play with friends and have fun. In short, I think that people shouls make use of technology advances’ advantages appropriately.
