Schools are going to change. For instance: now, we have to come school but in 2020, students won't have to come to school. People are going to change. For instance we do all the housework ourselves at home but in 2020, robots will do it for us. New electronics will be discovered. The technology will make people’s life easier on the other hand it will make them lazy. Technology will improve a lot in the future. In past, people didn't know how to use a computer. They didn't have computers at home. They didn't have. If any people wanted to read a newspaper they had to go to store and buy a newspaper then they could read it but now if any body wants to read a newspaper, they don't have to go to a store, they can go to internet and they can read a newspaper online. They can do this at home too. This means that life in 2020 will be more different from present. Maybe people will get the news transferred to their brains via Internet. I think life in 2020 will be different from present because of new technology. Technology will be more advance in future. It will make people’s lives more comfortable which will make them a little lazy.
